Parking Indicator using Arduino

Parking Indicator

In the previous article we have discussed how to use the Ultrasonic sensor. This time we will make a project parking distance indicators.

Have you ever parked your vehicle but rammed backward someone, walls, power poles, and others when you park your car? One reason is that you do not know there’s something behind your car. This indicator that we will create is useful to know…

HC-SR04 Ultrasonic sensor using Arduino

Ultrasonic sensor

HC-SR04 ultrasonic sensor is a sensor that can transmit sound waves and watching the reflections that can be used to determine the distance between the sensor and the object that reflects the sound waves.

Sensor HC-SR04 that can handle the range from 2 cm to 400cm, with a level of precision 0,3cm. Detection angle that can be handled no more than 15°. Current takes no more than…

Simple Calculator in Matlab

In the basic usage mode, MATLAB can be used as a calculator function. For example, we can do the following calculations in the command window.

>> 3+12 ans = 15 >> 25*10-16 ans = 234 >> (9+18)/3^2 ans = 3

Basic arithmetic operators are supported by MATLAB are as follows:

+, -, *, / : Plus, minus, multiply, for (,)           : Brackets \             : Division reversed ^        …

1.4 Get Help Matlab

Help Matlab

Get Help Matlab – MATLAB has a system of “help” extensive, detailed documentation and information containing “help” includes all the commands and functions in MATLAB. This system will help us, both beginners and experts, to understand the functionality of MATLAB that we have never used before. To get help, there are two ways: through the command window, and through the help browser.

1.3 Demo In Matlab

When it was opened MATLAB, we can run the demo in it. From the command window, type in demo, it will appear in the browser window where we can choose demo which will be executed.

Figure 1. 5 Window start a demo.

We can see and feel the various applications of MATLAB by way of exploring a demo. Within the demo There are some games that we can play, graphics are appealing, and a simulation of a…

1.2 Try Ability Matlab

If this is your first time using MATLAB , it’s good we tried some command to glimpse the various MATLAB capabilities and advantages.

MATLAB we can use just like a calculator :

>> 2048 + 16 ans = 2064

Jot down a few commands in a single line :

>> 5^2, 2*(6 + (-3))

ans = 25 ans = 6

Create a variable to store numbers , as well as run a variety of command or function that already exists in MATLAB .

MATLAB is a computer program that can help solve various mathematical problems we often encounter in technical fields. We can take advantage of the ability MATLAB to find the numerical solution of various problems quickly, starting the most basic things, let the system 2 equation with two variables:

x – 2y = 32 12x + 5y = 12

to the complex, such as the search for the roots of…

RTC (DS1307) using Arduino

RTC (DS1307) using Arduino

RTC (DS1307) using Arduino – Real Time Clock (RTC) is a component which can produce the right time because it is equipped with a generator and battery. RTC can be used as a clock or calendar. RTC is one of the DS1307. DS1307 provides information of seconds, minutes, hours, day, month, date, and year. Hours can be operated on a 24 hour or 12 hour is PM or AM.

DS1307…
