Components used:-

Arduino UNO R3 board

Led Lights

BASICS-

Understanding the base of arduino learning by starting off with blinking the led lights

Setting up the interface:-

Just connect the longer wire of the led which is the live side of the led to the pin 2 of the arduino board and the smaller side to the pin 3 and then upload the following code;

Code:-

void setup()

{ pinMode(2,OUTPUT); pinMode(3,OUTPUT); } void loop()

{ digitalWrite(2,HIGH); digitalWrite(3,LOW); delay(1000); digitalWrite(2,LOW); digitalWrite(3,LOW);

delay(1000); }
