I need an arduino controller programmed to do the following. There will be 8 independent inputs with magnetic contacts at the end of each. When all the magnetic contacts are closed, I need the controller to send a signal to a mag lock to open a door. The maglock shall then remain open until a master reset button is pressed, even if one of the 8 inputs gets opened. Everything should be powered from 12vdc. If you have any further questions please dont hesitate to contact me...I am new to arduino so Im sure I will have plenty of questions myself.
