I am an A level student and for my DT project I want to make a product which incorporates a microphone causing around 150 LEDs to flash in time to music being played from an external source. I have realised that I will need to include a power amp but- after research on the internet- none of them seem to work. I am using a n electret microphone but I can purchase one which would work better- if anyone knows? Also, does anyone have a circuit design I could look at for some help? I know 150 LEDs is a lot and I am a little lost at the moment.
THANK YOU!
