Hi! I’m interested in using the OpenGrab as a theatrical special effect. We’re trying to make a prop shelf fall on cue while out on stage away from anyone. My thought was to find some sort of “always on” magnet and trigger it with a DC relay via Arduino to “OPEN” the circuit and make the shelf fall. Would this OpenGrab do the trick? Is it as simple as sending it a 5V DC signal to OPEN this circuit and break it’s magnetism?
