Hi, my name is Rahmat Hidayat. I code for fun and sometimes share my code here so I can reuse it later. Feel free to use or modify this project. If you need help setting it up, follow this tutorial.

Adafruit has this week announced the arrival of the new Arduino RGB Matrix Shield which is now available to purchase priced at $5.95. Any of your projects that use a Arduino-compatible board, equipped ...

The Arduino code used to control the RGB LED is provided below. It controls each RGB channel individually and uses timed delays to create the blinking color sequence. You can copy the code into the ...

The video for this Dev Lab is available on YouTube where the video description includes links to further information. This Dev Lab integrates Adafruit's 13x9 RGB LED Matrix into Bluetooth and Matter ...

Building IoT projects with touchscreens used to be a headache, involving numerous components, messy wiring, and endless troubleshooting. But the ESP32-S3 Box-3 makes things way easier. It is an all-in ...

It started with a simple question: What if my hand could control the color of an LED? So I decided to turn a normal RGB LED into a small gesture-controlled system. The idea was simple: I would use my ...

This system uses a colour-changing LED (RGB LED/tri-colour LED) that switches to a new colour every 5 seconds. Simultaneously, the colour name is displayed on an OLED mini screen (SSD1306). This ...

The most fascinating project you can build is something with a bunch of blinky hypnotic LEDs, and the easiest way to build this is with a bunch of individually addressable RGB LEDs. [Ole] has a great ...
