how to control LED lights with Arduino arduino Simple project with code — how to control LED lights with Arduino

The Arduino board enables the creation of various electronic circuits and their control by programming codes. In this post we will learn how to control LED lights with Arduino. as shown in video in the end of the page.

Electronic components needed :

To make this simple project we need these following components :

3 Led ( red, yellow, blue )
3 Resistance ( 220 Ohm )
Electrical wires
Arduino UNO
Breadboard

Schema of the circuit

Arduino programming code:

int LED1 = 10 ;
int LED2 = 11 ;
int LED3 = 12 ;

// by andprof.com
void setup() {
  // put your setup code here, to run once:
pinMode(LED1,OUTPUT);
pinMode(LED2,OUTPUT);
pinMode(LED3,OUTPUT);

}

void loop() {
  // put your main code here, to run repeatedly:
digitalWrite(LED1,HIGH);
delay(100);
digitalWrite(LED2,HIGH);
delay(100);
digitalWrite(LED3,HIGH);
delay100);

digitalWrite(LED1,LOW);
delay(100);
digitalWrite(LED2,LOW);
delay(100);
digitalWrite(LED3,LOW);
delay(100);
}
