I am completely new to scratch and I was wondering what the most simple way of coding GPIO high/low input pins were? I was hoping to implement cases where, when a certain GPIO pin is low, a note is played from the midi sound system using a pHAT DAC with a Raspberry Pi Zero. Any help would be greatly appreciated.
I didn't find the right solution from the Internet.
