What is Smart Cellphone Holder Circuit Design about?

This circuit uses an LM555 timer IC to create an infrared sensor that detects when a cellphone is placed in a car phone holder. When the phone is present, no action occurs. But when the phone is absent, an LED flashes to notify the driver. The circuit draws power from the car battery and attaches to an existing phone holder or can be custom built. It aims to prevent drivers from forgetting their cellphone when exiting their vehicle.
