This is the most basic tutorial for the famous open source development board named ARDUINO

RASPBERRY PI tutorials are on the way,please wait.

Step 1: COMPONENTS REQUIRED

1.LED(any color,iam using onboard led in digital pin 13)

2.ARDUINO WITH USB CABLE

3.JUMPER WIRES

4.BREADBOARD

Step 2: WIRING THE COMPONENTS

Wire the components as shown in diagram and next step is how the code works.

1.The long leg of led is positive pin and short leg is negative pin or ground pin

2.connect the long led to digital pin 13

3.connect the short leg to any ground in the arduino board.(on board it will be named GND)

Step 3: CODING USING ARDUINO IDE

You can download the new ARDUINO IDE from the official website,this is an integrated development environment and easy to use programming tool,this is used to code all the arduino develoment boards.In next step I will show you how exactly the code works

1.Open arduino ide

2.click file-new

3.type the following code

4.void setup() {

pinMode(13, OUTPUT); }

void loop() {

digitalWrite(13, HIGH);

delay(1000);

digitalWrite(13, LOW);

delay(1000); }

5.Make sure you have selected the correct port and board,you can verify this by checking in Tools options situated in the top of the IDE.

Step 4: WORKING OF THE CODE

void setup()-runs when you power the board or press reset

void loop()-runs over and over.

pinMode(13, OUTPUT);-configure the arduino pin 13 to be an output pin.

digitalWrite(13, HIGH);-set the logic level of pin to be high (5V)

digitalWrite(13, LOW);-set the logic level of pin to be low (0V)

delay(1000);-wait for a second(1000=1second)

Step 5: CONCLUSION

Congratulations for successfully completing the tutorial you can modify this code to work with more than one led and even create a pattern of lights ,feel free to try out different things using this board and dont forget to watch my other instructables too.
