Project #401
Oscillation
Sounds (III)
OBJECTIVE: Show variations of project 399.
Use the circuit in project 399. Connect the
whistle chip (WC) across points B & E.
OBJECTIVE: To make sounds with an oscillator circuit.
Turn on the switch (S1) and the speaker (SP) emits an oscillating
sound. Now connect the whistle chip (WC) across points A & B and
the sound changes.

Oscillation Sounds (II)

OBJECTIVE: Show variations of project 399.
Use the circuit in project 399. Connect the whistle chip (WC) across
points C & D.
Project #402

Sounds (IV)
OBJECTIVE: Show variations of project 399.
Use the circuit in project 399.
whistle chip under capacitor C2. Turn on the
switch (S1) and the circuit oscillates at
another frequency.

Oscillator
OBJECTIVE: Show variations of project 399.
Install the Using project 399, replace the 100kΩ resistor
(R5) with the photo resistor (RP). Wave your
hand over the resistor and the frequency
changes.
