Abstract
Abstract The auto-wireless shutter release control is a mechanism that will allow the user to take a photograph by remote control. The system is comprised of an emitter that upon activating (push button) sends out a wave signal that is accepted via a receiver, which in turn activates a solenoid that pushes a cable plunger, releasing the camera shutter button, resulting in the photograph being taken.
