2.

Place your breadboard push button between E6, F6, E8, and F8.

3.

Put the battery in the battery holder. Then plug the positive (+) wire from the battery holder into F10 and the negative (–) wire into D6.

The Hows and Whys: Breadboards have metal plates inside them that allow quick, easy connections between a power source and an actuator. When you connect the negative side of the battery to the negative sides of the buzzer and the button, you can use the button to complete the circuit. When the button is pressed, it connects the positive sides. The circuit is completed.

S T E A M CONNECTION: This project is a good example of how we can use sound in our circuits. Once we understand that sound can be a part of electronics, we think about creating circuits that make music.

Now Try This: What other things could you make happen when you push a button? There are so many ways for you to modify this basic design. You could make a doorbell that uses light. This device is often used by people who are deaf or hearing-impaired instead of a ringing doorbell. A flashing light lets them know someone is at the door.
