Hello. I'm back on this project - powering a 12V motor in 2 directions with 2 relays, 2 transistors, Arduino Nano and a 12V DC adapter.
Just to make sure I understand the diagram- the coils will be powered through the 12V adapter? (only when the transistor is cunductive of course)
Also, what is the 1N4007 (light blue part) used for in here? i Google said it's an AC/DC adapter so I don't understand.
Thank you
