Hello. I'm trying attempting my first electronics project and need a little help. The project is a key finder(I'm aware you can buy them). So far I know I need to make a mic preamp circuit and a switching circuit. I was just wondering how to put the 2 together. The diagram shown is for a switching circuit, and I wanted to know if I can put the mic preamp circuit in where the transmitter is supposed to go instead. Would that work?
And here are my parts:
1 piezo buzzer
4.7kOhm resistors
220kOhm resistors
2.2kOhm resistors
perfboard
NPN switching transistors
10uf capacitor
100uf capacitor
condensor mic
red led
2N3055 transistor
Am I on the right track atleast? I also uploaded the mic preamp diagram I'm using if anyone needs it... Thanks a lot!
