simple circuit mini bicycle bel

Posted on Feb 5, 2014

This circuit is a mini bicycle bell. Mini bicycle bell is connected using the bell as a switch. If the button is pressed, an electric current flowing on the 9V voltage electronic circuit through the transistor Q1. because the speakers are connected to the battery using a transistor Q2, when the transistor electrified, the speakers will also be ele

ctrified and sounds. Capacitor is used to the sound of the speakers is not a quick stop. Here is a schematic drawing mini bicycle bell: For the development of this circuit you can replace the switch S1 with the proximity sensor circuit. here I also include a PCB (printed circuit board) of the simple circuit mini bicycle bell and you can also download it.
