I am in the process of building ver 2 pcb and i want section control for my sprayer. I am using usb I
I chose to go with a older board for my first build instead of the aio.
So can someone suggest which section control is my best choice.
Thanks
Up to you. The USB Arduino machine ino Arduino ino is a good place to start. Use to be able to download zipped folder than contained all info files. I can’t find that now. I made new tabs in ide and copy pasted code and name on each tab. Buy a relay board designed for Arduino with # of relays you want.
