Project #514
OBJECTIVE: To make a low-frequency oscillator.
Build the circuit and set the adjustable resistor (RV) control all the way
to the right. Turn on the slide switch (S1) and you hear a sound like a
faucet dripping. You can speed up the dripping by moving the
adjustable resistor control around.
Leaky Faucet
Project #515
OBJECTIVE: To show how switches allow circuits to operate
independently even though they have the same power source.
This circuit combines projects #1, #2, and #6 into one circuit.
Build the circuit and place the fan on the motor (M1). Depending on
which of the switches (S1 & S2) are on, you can turn on either the
lamp (project #1), the motor (project #2), or both together (project #6).
