There are so many nice hacks in [Joekutz]’s retro LED display project that it’s hard to know where to start. There’s his DIY LED display controlled by an Arduino UNO. To have some… ...

Recently, we published an entry-level Arduino project with a single seven-segment LED display. Although it’s an amazing DIY project, we noted that most of the readers are looking for more advanced ...

This is a great way to use an LED strip that would have otherwise gone to waste. If you can’t find a scanner with a color wand like this one, you can always start with an RGB strip.

Inputs HSV color values via the serial monitor. Converts HSV to RGB using Arduino code. Controls an RGB LED connected to Arduino pins (typically pins 9, 10, and 11) through PWM to display the color.

This is a simple 0 to 9 counter circuit constructed using Arduino! Here, a common cathode 7-segment LED display is connected to Arduino for displaying the digits. The code (Arduino sketch) allows push ...

In this approach, Arduino is used as the sole framework. It’s typically run using the Arduino IDE or PlatformIO in Arduino-only mode. This is the standard way of running Arduino and focuses ...
