Our project is infact an Arduino with Serially Interfaced MAX7219 Operates an 8X8 LED Matrix to display a heart pattern. The MAX7219 IC is a serial input/output common-cathode display driver that ...

This setup allowed [Alex] to control all 128 LED’s with just seven bits, but it was too slow for him. His solution was to control the multiplexers with counter IC’s. The Arduino can just ...

Most of us have an 8x8 LED matrix from one of our Arduino kits. What can we do with them? This module investigates how to use these interesting devices. Along the way, we describe a fun electronics ...
