Re: Using Megadrum and Arduino together with Midi In and Out
Posted: Tue Jan 17, 2023 2:06 pmMIDI on the MCU level is just a serial protocol so you can connect In/Out pins used for MIDI directly provided both MCU on the same power voltage. MegaDrum is on 3.3V. If I remember right UNO is 5V so you will need level shifters between them.
