Electronic Quiz Buzzer Circuit Diagram using PIC Microcontroller. Khaleel January 31, 2014. Usually high level quiz competitions are very much time oriented as it becomes significant to determine who has answered first. So here we’ll see how to make a buzzer system that helps to decide the winners. Simple Piezo Buzzer circuit diagram and project details ... • Simple magnetic buzzer circuit with UM66 IC • Simple Piezo buzzer circuit with UM66T IC • Simple Piezo Buzzer circuit diagram and project details. I feel that the mechanical bell type operation of the alarm could be easily replaced by one of the above circuits; the only problem being that the voltage available is only 1.5V. How to Make a Homemade Buzzer? Simple Circuit Design Explored The circuit description given below will surely help you to understand better regarding how to make a buzzer: As can be seen in the circuit diagram, the circuit uses just one transistor, two resistors, a buzzer coil and a piezo electric transducer. Electronics Club Circuit Symbols Circuit symbols are used in circuit diagrams showing how a circuit is connected together. The actual layout of the components is usually quite different from the circuit diagram. To build a circuit you need a different diagram showing the layout of the parts on breadboard (for temporary circuits), stripboard or printed circuit board. Beeper & Buzzer Electronic Circuits: A Simple Circuit electronic buzzer This very simple circuit just uses a couple of resistors, a capacitor and the easily available 555 timer IC. The 555 is setup as an astable multivibrator operating at a frequency of about 1kHz that produces a shrill noise when switched on.
