A universal remote control system is disclosed. The universal remote control includes a receiver that has a wireless signal receiver unit, an electric motor that drives a mechanical arm and a microprocessor. When the receiver receives a control signal from a wireless signal transmitter, the microprocessor will energize the motor which drives the mechanical arm toward a pushbutton switch of a controlled device, such as a garage door opener, and depresses the push button, therefore activating the garage door opener. A feedback signal, for example, from the mechanical arm or the motor, may be provided to the microprocessor to inform the microprocessor when the pushbutton switch is sufficiently depressed and is in an engaged state. When the switch is in the engaged state, the motor will reverse its direction, causing the mechanical arm to raise and move back to a standby position.
