[Alex] needed a project for his microcomputer circuits class. He wanted something that would challenge him on both the electronics side of things, as well as the programming side. He ended up ...

The gadget is built around two main circuit boards, the LED Matrix and the Host master board.In a previous project, I shared the making details of an 8x8 LED matrix. For this project, I expanded the ...

Arduino has launched its next generation of UNO boards, introducing a 32-bit Renesas microcontroller and Espressif ESP32-S3 module, one-click cloud connectivity and plenty of I/O plus a 12×8 red LED ...
