A lightweight Arduino library for controlling MAX7219 LED driver ICs with 7-segment displays. Optimized for memory-constrained microcontrollers like CH32V003 and other Arduino-compatible boards. The ...

In this step-by-step tutorial, we're diving into the world of electronics and microcontrollers to create a personalized 8 by 8 LED matrix that can be controlled using an Arduino board In this ...

Original code is from HAZI TECH. I modified the code, add bar mode and peak hold. I build this using spare Arduino Nano and MAX7219 matrix display which I have been using in my previous DIY. So I just ...

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 ...

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 ...
