Last week, we have finish installed the Sound Trigger circuit on strip-board but we didn't have the chance to try the circuit yet because we don't have a 12V supply. So this week, we manage to get the power supply, so we test the circuit out.
The complete circuit that has been installed properly on strip-board
12V DC power supply
The almost complete Sound Trigger prototype.
After test the circuit, we find that it did not respond to any noise. Our circuit become like a normal lamp circuit, because when we switch on the power supply, the lights comes on without hearing sound and it will off after one minute. The lamp of our circuit should be only comes on whenever a noise is heard.
We decided to consult with Sir Saiful first before we start to do Troubleshooting.
