Hi, i need some help creating a circuit that allows me to read 64 button inputs with Arduino.
I have to be able to read multiple buttons beeing pressed at the same time.
I thought of creating a 8x8 button matrix but my buttons use 4 pins and i dont really know how to wire them into a matrix properly.
also ghosting would be an issue when using an 8x8 matrix.
I thought about using diodes to prevent it.
I have both 74HC595 aswell as 74HC165 available.
Any help would be appreciated
Using Arduino Leonardo / pro micro
thank you :D
