Ding Dong Sound Generator Circuit

A complete Video Guide to make this Circuit

Components Required
  • Battery
  • 555 IC
  • Resistors
  • Polarized capacitors
  • Buzzer
  • variable resistors
How This Circuit Works:
The 555 timers in this circuit produce a output whose frequency is such that the buzzer sounds ding dong.In this Circuit I change the arrangement of pins in 555 timer to make the circuit more simple,because less and arranged wiring makes the circuit simple and easy to understand.
You can watch the video How to change the arrangment of pins.

Ding Dong Sound Generator Circuit

Steps To Make the Circuit On Proteus:




Open Proteus professional.exe and pick components from pick devices.



Place all the components on the screen as shown in upper picture and give them Specify values according to the picture.




Connect one component with the other as per diagram.Click on one edge
Of the first component and then click on the others edge , a wire will connect Both.


Diagnose each component value and connection.


Play the circuit if circuit works then congrats J otherwise repeat step 4.




Take a print out of the circuit for your presentation
