Crank doorbell here is an interesting hobby circuit of a crank door bell. So once the setup is completed when the switch is pressed the circuit loop is complete which causes the current to flow through the circuit. The main part of this doorbell circuit are two ne555 timer ics when some one presses switch s1 momentarily the loud speaker sounds a bell tone as long as the time period of the monostable multivibrator built around ic1. Connect the input wires on the transformer to the source circuit using the black to black white to white and ground to green method.
