4. Diode

  1. You’re going to build a circuit with a diode. The diode only lets air through in one direction, which can be very useful for different circuits!
  2. Build the breadboard setup.
  3. Squeeze the bulb and observe the flag.
  4. Notice how the bulb will reinflate by itself.
  1. Now add a diode to the bulb (see the breadboard setup).
  2. Squeeze the bulb and observe the flag. Why won’t the bulb reinflate?
