#blinking led

Electronic workshop organized by Brainy Toys for kids and children to teach in depth knowledge on electronics. How electronic gadgets works and what are their components. Electronic workshop for training about electronic goods, electronic parts, robotics parts, electronic circuit elements and accessories.

Electronic workshop training is comprises of design and routing circuits. Brainy Toys, located in Gurgaon provides electronics workshops for children of age group 6-14 years. Kids between 5 to 7 years can participate in electronic workshop during their winter vacation.

Week 1-Arduino trial#1 Blinking LED

Trying playing with Arduino for the 1st time and did a fool proof test :) :) :)

Read from left to right, top to bottom.

Photo 1:  Arduino and a blue LED

Photo 2:  Break down of LED Kathode (yes, with a K) and Anode

Photo 3: How the Arduino should look with the LED in it

Photo 4: Recalling how photo 2 looked, make sure to put the Kathode(shorter side) into the grounding pin on the Arduino (abbreviated GND) and the Anode (longer side) into pin 13.

Photo 5: The miraculous finish!  See vid below for demo.   Here is the Code and accompanying comments:

// A simple Blink demo that shows how to make an LED blink and introduces some of the basic functions / syntax of the Arduino

void setup()

{

pinMode(13, OUTPUT); 

//pinMode tells the Arduino which pin will be used and what it will be used for

//So in this block, I'm telling the Arduino to use pin 13 and to use it as an OUTPUT

//OUTPUT baisically means that it will ramp the voltage up to about 5v or it's max

//basic structure: pinMode(pin, mode)

}

void loop()

{

  digitalWrite(13,HIGH);

  //digitalWrite baisically turns a pin on or off using the value HIGH for "on" and LOW for "off"

  //digitalWrite will only work however if you specify which pin it applies to using pinMode.

  // basic structure: digitalWrite(pin, value)

  delay(5000);

  //delay() is a time measurement function built into the Arduino and measures time in milliseconds.

  //For exxample, 5,000 milliseconds = 5 seconds

  //delay() DOES NOT TURN OFF THE VOLTAGE TO THE CURRENT PIN!  It just tells the Arduino how long to keep the voltage flowing for.

  digitalWrite(13, LOW);

  delay(7000);

  //These last two lines baisically say, turn off the voltage to pin 13 and keep it off for 7 seconds.  Then the loop repeats.
