LED VU Meter Coffee Table
I'm working on building a VU meter that will respond to ambient noise into a coffee table that I am making, and I'm stuck on working out how to build the VU Meter circuit, and how to power all the LEDs. I planned on using a 10 LED VU meter kit, and somehow powering more than one LED for each subsequent step. The thing is, each level doesn't have the same amount of steps. The first four levels have 8 LEDs each, the next three have 16 LEDs each, and the last three have 24 LEDs each. The LEDs I'm using have a forward voltage of 2.0 volts, and a Max Power Dissipation of 105 mW. I don't know how to go about powering the LEDs or wiring the circuit. Any help would be much appreciated.
