Ticking Bomb circuit electronic

Ticking Bomb sound generator circuit electronic.

The circuit gets going by charging the 2.2uF and when 0.65v is on the base of the NPN transistor, it begins to turn on. This activates the BC557 and the voltage on the collector increases. This forces the small charge on the 2.2uF into the base of the BC547 to turn it on more.

In the electrical sector, a schematic diagram is usually used to describe the design or model of equipment. Schematic diagrams are usually utilized for the maintenance and repair of electronic and electromechanical devices / units. Original schematics were made by hand, using standardized templates or pre-printed adhesive symbols, but nowadays Electrical CAD computer software is often used.

In electronic design automation, until the 1980s schematics were virtually the only formal representation for circuits. More lately, using the progress of computer system technology, other representations were introduced and specialized computer languages were developed, because with the explosive development of the complexity of electronic circuits, classic schematics are getting less practical. As an example, hardware description languages are indispensable for contemporary digital circuit design.
