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.

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 ...

There are a few peculiar RGB LED matrices that have the same physical connection but work a bit differently -- they might have only have three shift register chains rather than six, or might use a ...

[Fjord Carver] brings together an RGB LED and CdS Photoresistor to make a color sensor. Those Cadmium Sulfide lights sensors usually have a very wide swing of resistance when exposed to varying levels ...

When you need to quantify the color of an object, you’ve got quite a few options. You can throw a Raspberry Pi camera and OpenCV at the problem and approach it through software, or you can buy an ...

On the Arduino Giga R1 Wifi, there is an RGB led that can be controlled. This is well documented. If you stack the Giga with a Display Shield, then on the Display Shield there is another RGB led, less ...

ANAVI Miracle Emitter is an open-source hardware ESP32-C3 WiFi and BLE controller designed to control 5V addressable RGB LED strips, which works with Home Assistant over MQTT and also supports the ...
