Design and Construction of Electric Doorbell

The purpose of the project is to design and construct an electric doorbell based on the principle of electromagnetism, powered and controlled by an Arduino circuit board. The goal is to bridge the gap between an old mechanical doorbell and a new Arduino technology and circuit board powered by a 12 volt battery. After the successful construction of the device, it was found to be very useful to the deaf and blind, as the LED component, when activated, blinks and notifies the deaf of the presence of a visitor or someone at the door. It is therefore highly recommended for homes and offices with such disabilities.
