Bag items:

  1. Regulator IC
  2. Buzzer
  3. 9V Battery
  4. Battery Connector
  5. Push Button
  6. Bread Board
  7. Jumper Wire


We can start by creating the noise from a buzzer on giving input from a push button. Power supply to the circuit is given from a battery after connecting wires to Breadboard. As we press the button, the circuit gets closed and current starts flowing in the circuit and buzzer gives the output in the form of noise.
