Arduino for blinking 4 led red light

The blinking of 4 LEDs with Arduino is a simple and educational project that will show a beginner how to use an Arduino board to control a few LEDs. By writing a basic program, you could make the LEDs blink in a sequence, therefore showing the way to control digital outputs on an Arduino. It's a good project for getting to know basic electronics, programming, and how Arduino boards function in an interactive and hands-on manner. Get your Arduino board and some LEDs to start creating your own blinking light show!

write Arduino code for blinking 4 led red light

cpp

#define LED1 2
