Hello all , this is my first post, (great site), My project, I bought a swing gate motor kit and have found out that the controller box is not working , company said I did something wrong and wont replace it, I have a circuit to use relays and a remote control it works well , but I would like to add something that sensors when the gate hits something like the car or person it stops, just like garage door opener, might be like current sensing, all ideas welcome thx Pete. here is the circuit I have used for the relays..
