How to Blink Multiple LEDs with Arduino | Blink Multiple LEDs | INNOVATIVE SCIENTIFIC INVENTIONS |

Hello Friends! Welcome Back to "INNOVATIVE SCIENTIFIC INVENTIONS". Today I will show you. How to Blink Multiple LEDs with Arduino UNO.

Circuit Diagram:

Code: 




                      //CODE


int led1 = 11;
int led2 = 12;
int led3 = 13;



void setup() {
pinMode(led1, OUTPUT);
pinMode(led2, OUTPUT);
pinMode(led3, OUTPUT);
}

void loop() {
 digitalWrite(led1,HIGH);   //Led1 Blink = 1 second
 digitalWrite(led2,LOW);
 digitalWrite(led3,LOW);
 delay(1000);

 digitalWrite(led1,LOW);
 digitalWrite(led2,HIGH); //Led2 Blink = 1 second
 digitalWrite(led3,LOW);
 delay(1000);

 digitalWrite(led1,LOW);
 digitalWrite(led2,LOW);
 digitalWrite(led3,HIGH); //Led3 Blink = 1 second
 delay(1000);
}
