There is so much you can do with WS2812B addressable LEDs once you learn the basics. However, always remember to choose the correct micro controller (or arduino board) based on the RAM requirements of ...

This project demonstrates how to build an RFID-based access control system using Arduino. The system integrates an RFID reader, servo motor, 16x2 LCD (I2C), three LEDs (Red, Yellow, Green), and a ...

To drive the LEDs, [Ole] is using an Arduino. Even though the WS2812s are individually addressable and only one data pin is needed, [Ole] is using five individual data lines for this matrix.

The design would need so many LEDs that it crossed the limit that an Arduino can address, thus there were two Arduinos to control the whole.

HACK Lab HackLED Pro is an Adafruit Sparkle Motion -like LED controller that runs a custom version of WLED and supports both WS2812 and RGBCW LEDs, making it ideal for DIY lighting projects, smart ...
