In this article I will add some simple Arduino LED projects starting with basic ones like how to turn on an LED, blinking, and more. Every step will have the code, the schematic, photos of the project ...

Here is an artistic Arduino project for the fun-minded. The circuit is an Arduino RGB LED controller running on a sweet ‘n’ simple code,but with a little hardware surprise outside the Arduino board.

If you don't have the physical components, you can simulate this project using Tinkercad. Create a new Tinkercad account if you don't have one. Create a new circuit in Tinkercad. Add an Arduino UNO, ...

The Arduino then controls the state of the LED using the active high enable line from the column multiplexer chip. [Alex] wanted more than just a static image to show off on his new display, so he ...

An Arduino hourglass project is a fun and educational project that involves creating a digital hourglass timer using an Arduino microcontroller and some simple electronic components. The project ...

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 ...
