Explanation This code will make two LEDs blink alternately. One LED is connected to pin 3, and the other is connected to pin 4. The code will turn one LED on while turning the other off, then switch ...

This Arduino project demonstrates the basic functionality of blinking a single LED using the Arduino IDE. The LED blinks on and off in intervals of three seconds. Connect your Arduino board to your ...

Here we are going to write a program to blink an LED for every 500ms. In arduino uno, a LED will be already designed at the pin13, but we are not going to use it. Here we are going to connect an ...
