Tutorial - Controllable Power Outlet
about 5 years ago
Fantastic tutorial! I very much enjoyed reading it.
I have a question for you.
I want to use a small Linux board to control 10 relays using its GPIO pins. Do you know of a relay that already has the circuitry (diode and transistor) so it can be controlled directly via GPIO without any extra circuitry?
Thanks again for a great article!
