Hello everybody I know I probably should post a schematic, but I think/hope this is a general question about how much power you can draw from an Arduino Nano... Anyway, I'm doing a project, that involves 10 Takamisawa RY5W-K relays. I did most of the development/breadboarding on an 'genuine' Ardui…
