Connect the whistle chip (with PC cable) across points C & D using a

1-snap, the sound and waveforms are different.

Project #PC52

Whistle Chip

Sounds PC (IV)

Place the 470mF capacitor C5 on top of

the 100mF capacitor C4, and connect the

whistle chip across points A & B. The

circuit oscillates in 2-second intervals.

Project #PC53

Bird Sounds PC

OBJECTIVE: To view the output of an oscillator circuit.

Build the circuit and try the settings shown. The oscillator
