How to connect ATtiny85 to multiple MAX7219 LED 8×8 Matrices
How we could work with multiple MAX7219 LED 8×8 matrices connected in a chain, light up some LEDs, and use a memory buffer to save the current state of the LEDs. In our previous tutorial, we discussed how to create an interface between the ATtiny85 microcontroller and MAX7219 controller and connect a single 8×8 LED matrix. The … Learn more …
