OBJECTIVE: To create the sound of a cat.
Set the variable resistor (RV) to the far left. Press and release the switch (S2). You
should hear the sound of a cat from the speaker (SP). Now adjust the resistor and
hear the different sounds.
Electronic Cat
Project #458
OBJECTIVE: Show variations of project 458.
Electronic Cat (II)
Project #459
Use the circuit in project 458. Connect the whistle chip (WC) across points A & B.
Press and release the the switch (S2). You hear sound from the whistle chip and
speaker (SP). Adjust the resistor (RV) and hear the different sounds.
Project #460
OBJECTIVE: Show variations of project 458.
Electronic Cat (III)
Project #461 Project #462
Project #463 Project #464 Project #465
Use the circuit in project 458. Connect the whistle
chip (WC) across points B & C. Press and release
the switch (S2). Adjust the resistor (RV) and hear
the different sounds.
OBJECTIVE: Show variations of project 458.
Electronic Cat (IV)
Use the circuit in project 458. Connect the whistle
chip (WC) across points C & D. Press and release
the switch (S2). Adjust the resistor (RV) and hear
the different sounds.
