I am brand new to Arduino. I have a project in mind. I have seen many people use the Arduino to allow Android devices control appliances using a Bluetooth module and a relay board. I want to do he same, but instead of just on and off I need a couple of the relays on the board to be momentary, as they will be controlling slide motors in my 5th wheel. The hard wired switch for them is a rocker on-off switch and wish to duplicate that.
My question is can that be done in a sketch or can that be done if I build an app in MIT app inventor.
