This project demonstrates how to build a color sensor detector using the APDS-9960 and the Adafruit Feather ESP32-S2 TFT (you can also use Adafruit Feather ESP32-S3 TFT) to control HomeKit devices through ItsaSNAP.
You can build a wonderful weather display using an Adafruit Matrix Portal S3 and a 64x32 RGB LED Matrix. Using CircuitPython, you can create a display that shows the current temperature and weather conditions using custom BMP graphics.
Our Matrix Portal Moon phase clock lets you know where things stand right here and now, portraying the Moon’s phase more accurately than a printed calendar, and whether it’s currently in the sky or has set.
Folks love Adafruit's wide selection of RGB matrices and accessories for making custom colorful LED displays... and Adafruit RGB Matrix Shields and FeatherWings can be quickly soldered together to make the wiring much easier.
