led chaser circuit

 

LED chaser circuit is a popular LED driving circuit used to display different lighting patterns. The lights available in the market are pricy. In this tutorial, I will show you how to design a simple and cost-effective LED chaser circuit using Arduino.

Working on a led chaser using Arduino

we have made an LED chaser circuit using Arduino and LED. This project is very simple and cost-effective.

Components used

These are components used in the LED Chaser circuit project

  • Arduino
  • LED (different colors according to your need)
  • Push Button
  • 5V battery
  • 220-ohm resistor
  • Connecting wires

when you turn on the push button the LED will start glowing from right to left one by one and then follow the same pattern from left to right. In this way, this circuit will work.

Coding LED Chaser Circuit

int led[]={2,3,4,5,6,7,8};
void setup() {
for(int i=0;i<=8;i=i+1)
{
pinMode(led[i],OUTPUT);
}

}
void loop() {

for(int i=0;i<=8;i=i+1)
{
digitalWrite(led[i],HIGH);
delay(500);
}

for(int i=8;i>=0;i=i-1)
{
digitalWrite(led[i],LOW);
delay(500);
}
}
