The circuit is driven by a MAX7219 IC that is being controlled through an Arduino microcontroller board, to create an 8X8 LED matrix. The connection of the LED matrix and the IC was done on a ...

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.

A digital camera has an array of sensors that captures light reflected or transmitted onto it. This build is something closer to a reverse camera – a single sensor that makes images on a matrix of ...

Check this out. Each block is made of a 8x8 RGB LED Matrix and a home-designed board based on a STM32 microcontroller running the FreeRTOS real-time operating system. They are able to communicate ...
