Is my electret mic faulty?
Hello , i am working on my final semester project.
im sorry im a complete beginner on this
I took computer science and this is my first sem , as far as what i've learned in class i wasnt taught on what are the transistors , resistors , capacitors do or even how to use the breadboard. I dont even know why i got this project on my first sem.
i have followed many tutorials that uses this same schematic except that they used a 9mm instead of a 6mm microphone that i used.In their videos …
I dont even know why i got this project on my first sem.
Hello , i am working on my final semester project. I have made a circuit on a breadboard that uses a mic to detect sound and light up leds. However when i finished the circuit , sound doesnt seem to get detected by the mic and the leds doesnt even lit up. When i inserted power to the breadboard the leds are lit up for a split second upon inserting the pins to breadboard. Is my electret mic faulty?Here is the schematic.
i used a 4k7 resistor to connect to the mic and used a 1uf capacitor instead of a 0.1uf. Then i followed the advice to put the leds in a series using one transistor.After that i used a 47uf to connect to the negative and positive power line.
Can you show a schematic of the working circuit?
