What is Touchless Doorbell Circuit Guide about?

The touchless doorbell circuit operates using a 9V battery that powers a voltage regulator to provide 5V to its components. An IR sensor detects motion and sends a signal to a relay board, which activates a buzzer to alert the homeowner. This system allows for a doorbell function without physical contact.
