Bare PCB #140092-1 for the project Doorbell Memory.

On occasion it may be useful to know when a visitor has called in your absence. This is also true in case of an enforced absence when a visitor is expected. This project helps to rectify the situation by providing a “memory” for a doorbell. On your return an LED will indicate whether or not a visitor had called.
