The loop function runs as long as the Arduino board is powered and will blink the LED ON and OFF withe 1 second pause between states. You can use another pin, for example pin 12 and then change the ...

This project demonstrates how to use an Arduino Uno to control an LED, making it blink at regular intervals. It's a foundational experiment for learning how to control digital outputs using Arduino ...

Home » Feature Story » Apps » Blinking an LED with the Arduino IDE. ... Open the LED blink example sketch: File > Examples > 1.Basics > Blink. You should see a window like in Figure 2. 3.

You could put the Arduino in deep sleep, if you wanted to and that LED will still blink. With a little work, you could probably adapt this idea to any number of circuits out of the 555 playbook ...

This project controls the onboard WS2812B (NeoPixel) LED of the YD-RP2040 board using the Arduino framework under PlatformIO. The LED logic is encapsulated in a custom C++ driver located in ...
