The ESPLORA Arduino game controller Board is an Arduino-compatible microcontroller board based on the Arduino Leonardo. Unlike previous models, it comes equipped with a variety of built-in sensors for immediate use in interactions.

This guide is perfect for individuals interested in using Arduino, but who don’t want to dive into electronics right away. To learn how to use the ESPLORA Arduino game controller Board in a simple and clear manner, be sure to read the Getting Started with Esplora guide.

The ESPLORA Arduino game controller Board boasts onboard sound and light outputs, as well as multiple input sensors such as a joystick, slider, temperature sensor, accelerometer, microphone, and light sensor. Additionally, it offers the option to enhance its functions through two Tinker-kit input and output connectors and a socket for a color TFT LCD screen.

Similar to the Leonardo board, the ESPLORA Arduino game controller Board also utilizes an Atmega32U4 AVR microcontroller with a 16 MHz crystal oscillator. It features a micro USB connection that can function as a USB client device, such as a mouse or keyboard. Additionally, there is a reset push button located in the upper left corner of the board for restarting purposes.

There exist four indicators, each displaying a different status.

The green indicator shows if the board is currently being powered.

The L [yellow] connects directly to pin 13 on the micro-controller for easy accessibility.

The [yellow] LED indicates data being transmitted or received through the USB connection.

Within the board lies all the necessary components to support the microcontroller. To begin, just connect it to a computer using a USB cable. The ESPLORA Arduino game controller Board is also equipped with built-in USB communication, allowing it to function as a mouse or keyboard when connected to a computer. It also offers a virtual serial/COM port (CDC). This alters the behavior of the board, which is further explained on our getting started page. On this page, you can find all the instructions for configuring your board and utilizing the Arduino Software (IDE) for coding and electronics experimentation.

The transfer of data, both in and out.

The ESPLORA Arduino game controller Board features a classic gamepad design, including an analog joystick on the left and four push buttons on the right. It also comes equipped with several onboard inputs and outputs:

The analog joystick features a center push-button and two axes, designated as X and Y. There is also a central pushbutton for added functionality.

Arranged in a diamond formation are 4 push-buttons.

The slider for the linear potentiometer is located towards the bottom of the board.

A tool to capture the volume (amplitude) of the surrounding environment.

A sensor that detects light to measure brightness.

The temperature sensor measures the surrounding temperature.

A three-axis accelerometer detects the orientation of the board with respect to gravity, along the X, Y, and Z axes.

The buzzer has the ability to generate square-wave tones.

The RGB LED features Red, Green, and Blue elements that allow for color mixing and a bright display.

The TinkerKit Inputs allow for easy connection between the sensor modules and 3-pin connectors.

The TinkerKit Outputs allow for easy connection of the TinkerKit actuator modules via the 3-pin connectors.

The TFT display connector can be used for a color LCD screen, SD card, or any other devices utilizing the SPI protocol.

To fully utilize all available sensors, the board employs an analog multiplexer. This way, multiple input channels (excluding the 3-axis accelerometer) can share a single analog input of the microcontroller. Selecting which channel to read is done through four additional pins on the microcontroller.

Communication is essential in any relationship, whether it be personal or professional. It plays a crucial role in maintaining strong connections and fostering understanding between individuals. Effective communication allows for open and honest dialogue, facilitating problem-solving and building trust. Without good communication, misunderstandings can occur, leading to conflicts and strained relationships. Therefore, it is important to prioritize effective communication in every aspect of our lives.

The ESPLORA Arduino game controller Board for the Leonardo offers various features for connecting with a computer, another Arduino, or different micro-controllers. The ATmega32U4 enables serial (CDC) communication through USB and is recognized as a virtual com port on the computer. It also functions as a full speed USB 2.0 device and can be used with standard USB COM drivers. A .inf file is needed for Windows.

The Arduino software comes equipped with a serial monitor for easy transmission of text data to and from the board. Whenever data is being sent via the USB connection to the computer, the RX and TX LEDs will light up on the board. Additionally, the ATmega32U4 has SPI capability accessible through the SPI library. In addition, the Esplora can act as a standard keyboard and mouse, allowing you to use programming to manage these input devices via the Keyboard and Mouse libraries.

The act of creating computer software, also known as programming, involves writing code using various languages and tools. This process requires a combination of problem-solving skills, critical thinking and creativity. Programmers must constantly learn new techniques and adapt to ever-changing technology in order to produce high-quality programs.

To start using the Esplora with your Arduino software (download), simply choose “Esplora” from the Tools > Board menu. For more information, refer to the getting started page. The ATmega32U4 on the Esplora comes pre-loaded with a boot-loader, enabling you to upload new code without an external hardware programmer.

The AVR109 protocol is the chosen method of communication. To avoid using the bootloader, you can program the microcontroller through the ICSP header. Additional instructions are available for reference.

A dedicated library for the Esplora simplifies writing sketches, with methods available for reading sensors and controlling onboard outputs. These high-level methods also perform pre-processing of data, such as converting temperature readings to degrees Fahrenheit or Celsius. Additionally, the library allows easy access to outputs like the RGB LED. For further information and examples, please refer to the Esplora library reference page.

The automatic reset and bootloader activation are key components in the software’s functioning.

Rather than relying on the physical reset button, the Esplora utilizes a software-based reset triggered by opening and then closing the virtual serial/COM port (CDC) at 1200 baud. This initiates a processor reset, temporarily cutting off the USB connection to the computer and causing the virtual port to disappear. The boot-loader remains active for approximately 8 seconds before it can also be activated by pressing the reset button on the Esplora.

Please be aware that upon initial power up, the board will launch the user sketch instead of the boot-loader, if available. Due to the specific reset process of the Esplora, it is most effective to allow the Arduino software to attempt a reset before uploading, especially if you typically press the reset button before uploading on other boards. However, in the event that the software is unable to reset the board, you can manually initiate the boot-loader by pressing the reset button on the board.

The USB port is equipped with overcurrent protection to prevent any potential damage.

The ESPLORA Arduino game controller Board comes equipped with a re-settable poly-fuse to safeguard your computer’s USB ports against shorts and over-current. While most computers have built-in protection, the fuse adds an additional level of security. In the case of a short or overload exceeding 500 mA, the fuse will disconnect the connection until the issue is resolved.

The power of

The external power regulator has a maximum capacity of 1500mA. Of this, 750mA is reserved for the phone and MEGA ADK board, while the remaining 750mA is dedicated to any attached actuators and sensors. To use this amount of current, a power supply must be able to provide at least 1.5A. While the board can run on an external supply ranging from 5.5 to 16 volts, it is recommended to use between 7 and 12 volts. If supplied with less than 7V, there may be insufficient voltage output from the 5V pin, potentially causing instability in the board. On the other hand, using more than 12V may result in overheating of the voltage regulator and potential damage to the board components.

What follows is:

This pin is used to supply voltage to the Arduino board when it is powered by an external power source rather than 5 volts from the USB connection or another regulated source.

This pin generates a regulated 5V from the board’s regulator. The board can be powered via the DC power jack (7-12V), USB connector (5V), or VIN pin (7-12V). If you supply voltage via the 5V or 3.3V pins, you bypass the regulator and can damage your board. Please do not do so.

The onboard regulator generates 3.3 volts. Maximum current draw is 50 milliamps.

The ground pins are GND.

The Arduino board’s IOREF pin serves as a voltage reference for the microcontroller. In a properly configured shield, you can determine the voltage of the IOREF pin and select an appropriate power source or enable voltage translators to work with either 5V or 3.3V outputs.

The memory

It has 256 KB of flash memory for storing code (of which 8 KB is used for the bootloader), 8 KB of SRAM, and 4 KB of EEPROM (which can be read and written).

The inputs and outputs

By using pin Mode(), digital Write(), and digital Read() functions, each of the Arduino Atmega 2560 R3 Android Accessory Development Kit (ADK)’s 50 digital pins can be used as inputs or outputs. There is an internal pull-up resistor of 20-50 Ohm on each pin. They operate at 5 volts. They can provide or receive a maximum current of 40 mA. Some of the pins have specialized functions:

Serial 0: 0 (RX) and 1 (TX), Serial 1: 19 (RX) and 18 (TX), Serial 2: 17 (RX) and 16 (TX), Serial 3: 15 (RX) and 14 (TX). Connected to the ATmega8U2 USB-to-TTL Serial chip on pins 0 and 1.

External Interrupts: 2 (interrupt 0), 3 (interrupt 1), 18 (interrupt 5), 19 (interrupt 4), 20 (interrupt 3), and 21 (interrupt 2). An interrupt can be triggered on a low value, a rising or falling edge, or a change in value using the attach Interrupt() function.

Providing 8-bit PWM output with the analog Write() function for PWM values 2 to 13 and 44 to 46.

SPI: 50 (MISO), 51 (MOSI), 52 (SCK), 53 (SS). These pins support SPI communication using the SPI library. They are also broken out on the ICSP header, which is physically compatible with Uno, Duemilanove, and Diecimila.

MAX3421E is the USB host.

The Max3421E

The following pins are used to communicate with Arduino via the SPI bus:

Seven (RST), fifty (MISO), fifty one (MOSI), and fifty two (SCK) are digital.

You should not use Digital pin 7 for inputs or outputs because it is used to communicate with MAX3421E

PJ3 (GP_MAX), PJ6 (INT_MAX), PH7 (SS) are not broken out on headers.

A built-in LED is connected to digital pin 13. When the pin is HIGH, the LED is on, when it is LOW, it is off.

Supports TWI communication using the Wire library. These pins are not in the same location as the Duemilanove or Diecimila TWI pins.

Android Accessory Development Kit (ADK) with Arduino Atmega 2560 R3 has 16 analog inputs, each with a resolution of 10 bits (i.e. 1024 different values). It is possible to change the upper end of the range of the pins by using the AREF pin and analog Reference() function. Other pins on the board include:

Reference voltage for analog inputs. Use with analog reference.

Reset. This line is typically used to add a reset button to shields which block the board’s reset button.

The communication process

The Arduino Atmega 2560 R3 Android Accessory Development Kit (ADK) offers various communication options, including connecting with a computer, another Arduino, or other micro-controllers. The ATmega2560 has four hardware UARTs for TTL (5V) serial communication. Additionally, the board has an ATmega8U2 that uses USB to provide a virtual com port for computer software. For Windows machines, a .inf file may be needed but OSX and Linux machines will automatically detect the board as a COM port. In the Arduino software, there is a serial monitor feature for sending and receiving simple textual data from the board.

When data is transmitted via the ATmega8U2/16U2 chip and USB connection to the computer (but not for serial communication on pins 0 and 1), the board’s RX and TX LEDs flash. Any of the MEGA ADK’s digital pins can be serialized with a software-serial library. TWI and SPI communication are also supported by the ATmega2560. The Arduino software contains a Wire library to simplify TWI communication, see Wire library for details. For SPI communication, use the SPI library.

The USB host interface given by MAX3421E IC allows Arduino MEGA ADK to connect and interact with any type of device with a USB port. It allows you to interact with many types of phones, control Canon cameras, and interface with keyboards, mice, and gaming controllers such as Wiimote and PlayStation 3.

The programming language

For details, see the reference and tutorials. You can program the Mega R3 Android Accessory Development Kit (ADK) with Arduino software (download). You don’t need an external hardware programmer to upload new code to the ATmega2560 on the MEGA ADK since it comes preburned with a boot-loader (just like the Arduino Atmega 2560 r3). The STK500v2 protocol (references and C header files) is used for communication.

You can also bypass the bootloader and program the microcontroller through the ICSP (In-Circuit Serial Programming) header using Arduino ISP or similar; see these instructions for details. Atmega8U2 firmware source code is available in the Arduino repository. An ATmega8U2 is loaded with a DFU bootloader, which can be activated by:

The Rev1 boards have the following features:

Resetting the 8U2 requires connecting the solder jumper on the back of the board (near the map of Italy).

Rev2 and later boards have a resistor pulling the 8U2/16U2 HWB line to ground, making it easier to put into DFU mode. To load a new firmware, you can use the FLIP software (Windows) or the DFU programmer (Mac OS X and Linux). If you prefer, you can use the ISP header with an external programmer (overwriting the DFU bootloader). See this user-contributed tutorial for more information.

Reset (automatic) software

The Arduino Atmega 2560 r3 ADK has been designed to reset by software from a connected computer instead of requiring a physical press of the reset button before an upload. This is achieved by connecting one of the hardware flow control lines (DTR) of the ATmega8U2 to the reset line of the ATmega2560 through a 100 nano-farad capacitor. Whenever this line is asserted, causing it to drop low, the chip will be reset momentarily. The upload button in the Arduino environment makes use of this feature, enabling you to easily upload code without needing to manually press the reset button.

As a result, the boot-loader’s timeout can be reduced since DTR can be synchronized with the upload initiation. This arrangement also has additional effects when the MEGA ADK is linked to a computer running Mac OS X or Linux. Upon being connected to software via USB, the board resets and enters bootloader mode for about half a second. During this time, any non-code data will be disregarded by the programmed bootloader, but it will capture the first few bytes of data transmitted after the connection is established.

Ensure that the software your sketch is communicating with allows for a brief pause after establishing the connection before sending any initial data. The MEGA ADK has a trace that can be removed to disable the auto-reset function. Connect the pads on either side of the trace to re-enable it, labeled as RESET-EN. Alternatively, you can disable the auto-reset by connecting a 110-ohm resistor from 5V to the reset line; additional information can be found in this forum thread.

Over-current protection for USB devices

A resettable polyfuse protects your computer’s USB ports from shorts and overcurrents with the Arduino Atmega 2560 R3 Android Accessory Development Kit (ADK). In spite of the fact that most computers have their own internal protection, a fuse provides an additional layer of protection. When more than 500 mA is applied to the USB port, the fuse automatically stops the connection.

Shield compatibility and physical characteristics

The Mega R3 Android Accessory Development Kit (ADK) PCB has a maximum length and width of 4 inches and 2.1 inches respectively. The USB connector and power jack extend beyond the length, while three screw holes are available for surface or case attachment. It is important to note that the distance between digital pins 7 and 8 is 160 mil, which is not an even multiple of the standard 100 mil spacing for the other pins. Additionally, the MEGA ADK can be used with most shields designed for the Uno, Diecimila or Duemilanove boards.

The digital pins 0 to 13 (as well as the adjacent AREF and GND pins), analog inputs 0 to 5, the power header, and the ICSP header are all positioned in the same spot. In addition, the main UART (serial port) is located on the same pins (0 and 1); as are external interrupts 0 and 1 (pins 2 and 3). SPI is also available through the ICSP header on the MEGA ADK and Duemilanove / Diecimila.

Uno R3 CH340G ATmega328p Development Board is a low-cost version of the Uno R3. It uses a CH340 USB to Serial converter chip instead of an Atmega16U2.

It has worked perfectly for us when we used a lot of low-cost Arduino boards with CH340 chips. This board works exactly like the more expensive version without the CH340 chip during normal operation. The CH340 chip is only used during programming and when using the serial output of the USB port.

The following are the main changes from the previous version:

This jumper has two rows of pin holes (male and female), so it can be connected to normal female jumpers.

There are three additional rows of holes for wiring.

The ATMEGA328P DIP package has been changed to a flat package.

The CH340G replaces the ATmega16U2

Here’s how to use it:

The Arduino IDE can be downloaded here

The USB chip driver can be downloaded here

The driver will be automatically installed when you plug in the UNO development board

Choose the UNO from the die

The COM port should be selected

The best choice first, Arduino UNO SMD comes with routine procedures, burn them in. The Arduino Uno SMD CH340 microcontroller board is a compact yet powerful development platform that unleashes creativity in electronics and programming enthusiasts. The CH340 USB-to-serial chip ensures seamless connection with your computer while inheriting the legacy of the Arduino Uno.
