Firstly Hi!...noob here....
Im trying to do a project with my two lads and dont know a great deal about electronics. I know what we want to acheive, I think I know whats missing but dont have the knowledge to work out the particulars.
Ive attached what we have worked out so far.
We want:
10 LED's to light up to music (all at the same time not a bar type thing).
To be able to turn it off and on.
To be able to turn off the light syncing leaving all LED's lit.
To be able to adjust the Microphone Sensitivty.
At the moment I believe the power from the Microphone needs to be amplified but I dont know how or how much to amplify it by. Id also like to know the workings out behind it I dont just want a solution, I want to learn.
The transistor we are using is a TIP31c. (VCEO 100, IC 3, PTOT 40)

The Mic :
(0dB = 1V/µbar at 1kHz, Vcc = 4.5V, Rl = 1kΩ) 60dB ±3dB

I would appreciate any help or nudges in the right direction.
