Basic Circuits

An electric circuit is an unbroken way, an electric current exists and/or is able to pass out from it. A simple electrical circuit consists of a power source and a small lamp to which the free ends of the wires leading from the cell are attached.

When the connections are made properly, the circuit will “close” and current will flow through the circuit and light the lamp.

Here is simple electronic circuit project for Police Lights associate crystal rectifier circuit diagram.  This circuit uses a 555 timer that is setup to each runn in associate Astable operative mode. This generates a nonstop output via Pin three within the type of a sq. wave. once the timer's output changes to a high state this triggers the a cycle the 4017 4017 decade counter telling it to output consecutive sequent output high. The outputs of the 4017 ar connected to the LEDs turning them on and off.
