Trying to fully understand what I need to interface the cd74hc4067 chip to a pro micro. This is a small section of the schematic but it is functionally the same just with three chips and 38 buttons. Ive made button boxes before however it wasn't viable here and im completely new to multiplexers. TIA let me know if more info is needed
Edit solder pads on the right are named with corresponding pro micro pins
Edit 2:
After looking at this pic
It looks like something like this could work connecting com and vcc with a 1k resistor as shown here
