The Arduino LED blinking control project is the easiest project for beginners learning Arduino programming. The blinking of LEDs is controlled smoothly.
This simple project can be used to create a range of electronic innovations, such as traffic lights and other creative applications.
In this article, we’ll walk you through how to control LED lights with an Arduino, step by step.
Electronic components that we need:
- 3 LEDs
- 3 resistors (220 Ohm)
- Electrical wires
- Arduino UNO
- Breadboard
Circuit diagram:
Arduino Programming Code:
int LED1 = 10;
int LED2 = 11;
int LED3 = 12;
// by www.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);
delay(100);
digitalWrite(LED1,LOW);
delay(100);
digitalWrite(LED2,LOW);
delay(100);
digitalWrite(LED3,LOW);
delay(100);
}
