Welcome Friends, today I’m going to show you how you can make a led scrolling Matrix board using Arduino UNO, Nano or Atmega328p IC.you can make 8×32, 8×40, 8×48 all those with the same code. If you are making an 8×32 matrix then need 4 pcs Matrix driver 74HC595 IC (4×8=32), for 40×8 matrix then need 5pcs 74HC595 IC, meanes Singel 74HC595 IC can control a maximum of 8 LEDs.
Componenet Required
