Hi Im new to Arduino. Im trying to hook up an Arduino to a RC transmitter to control an RC blimp motor. The RC controls are digital basically on or off, when you press the button you basically close the circuit. I am not sure if this can be controlled through the arduino. I know some people use solenoids to do that to physically press the switch. But since there are 6 buttons it would be too many solenoids, in addition from what i understand solenoids nees special wiring so they dont damage the arduino and they can overheat and get damaged. Any feedback would be incredible. Thanks for any help/ideas.
