• Battery • USB Cable
• Battery OTG Socket • Magnetic Board
• 2 Jumper wire
Step 2 Place the buzzer and switch in series on the magnetic board.
Step 3 Attach the 2 jumper wires to the negative terminals of the
buzzer.
Step 4 Attach the 2 jumper wires to the negative terminals of the push
switch.
Step 5 Connect the battery. Attach the positive terminal of the battery
to the switch and the negative terminal to the negative terminal
of the buzzer.
Output
When the push switch is pressed, the buzzer makes a
sound, like a doorbell ringing. When the switch is not
pressed, the circuit is open, and the buzzer is silent.
Concept
This activity helps students understand how a push switch can be used
to control a buzzer. The circuit is completed when the switch is pressed,
allowing electricity to flow from the battery to the buzzer, making it ring.
Students discover that when the switch is not pressed, the circuit is open,
and no sound is made. This introduces students to the idea of open and
closed circuits in real life.
