Project: Sound Up and Down!!

Sound Up and Down!!

Component Required :

The components we required for this project are: 

  • Power Junction -1

  • POT Dimmer -1

  • Buzzer -1

  • Gray plate -1 

  • CT2 -8

  • Power bank -1

  • USB to DC Jack -1

Circuit Connection :

Now let’s start with the circuit. 

  • Take a power block and attach a POT dimmer to it.

  • And lastly, add a buzzer.

  • Connect the CT2 at the bottom of the all mini PCB and place the circuit on the Gray board. 

  • Our volume up and down circuit is ready. 

  • Turn on the power block and you can see the amount of current passing through the circuit. 

The buzzing sound of the buzzer will be dependent on the amount of current passing through it. Try rotating the knob in a clockwise and anticlockwise direction. You will notice that the sound intensity increases and decreases as you rotate the knob.
