Project #453
OBJECTIVE: Build a circuit that records the sound of the motor
spinning.
Placing the motor (M1) (with the fan attached) next to the microphone
(X1) enables you to record the sound as it spins. Turn off and then turn
on the switch (S1). After the two beeps, turn off the slide switch (S1)
again. Remove the jumper wire connected across points A & B and
press the press switch (S2) to hear the recording. The lamp (L2) is used
to limit the current and will not light.
