You'll need an Arduino and some small miscellaneous electronics parts to make it happen, and if you're familiar with building on the Arduino (which we've talked about before), it shouldn't be too ...

Because some hardware setup is required to build up a functioning radio, an Arduino can be used to supply the voltage and control the radio chip. The 3.3-V power can be taken from the Arduino’s ...

Inside you’ll find an Arduino board, microphone, and an 8×8 RGB module. The front cover of the project box diffuses the light using a sheet of tracing paper on a frame of foam board.

This project has been tested with Arduino UNO R4 WiFi, Arduino UNO R3, and ESP32, so you can use any of these. However, there may be minor code adjustments for each microcontroller. Arduino UNO R4 ...
