I had the idea to pilot a 8 relay board I had to control 4 x 220C power plug and 4 x 12V output.
I am using a LCD from saintsmart on an arduino Mega to display button that will set on & off the power plugs. There is also an old laptop 12V supply for the 12V power, arduino and the 5Vregulator for the relay board.
I added a GPS and RH22 sensor to display also the time and the temperature.
Enjoy this project?
