- You’re going to build a circuit with components and resistors in parallel. You will see that adding resistors in parallel increases airflow to these components.
- Build the breadboard setup.
- Turn on the pump and press the tubes connected to the resistors (kink them) one by one until they are completely shut. Notice how the diode sound changes.
- Now we’re going to experiment with a bellow. The bellow can’t release the pressure inside, so it’s wise to put a resistor in parallel to the bellow.
- Play around with the resistors to see how closing them (eliminating them from the circuit) influences how much pressure builds up inside the bellow.
- Add another button so you can also release the pressure from the bellow.
