For the past 3 weeks I've been working on this, and now I'm stuck. I need some help, so here it goes.
I'd like to design a circuit that will allow me to pulse EL wire to a beat. It's for an EL Wire Sweatshirt. I have the EL Wire controller circuits working great. My goal is to design a circuit I can feed an Arduino Fio, powered by a 3.7VDC (850mAh) LiPo, that listens to music from a microphone, amplifies it, finds the beat, then feeds the ADC. I've tried 6 different methods and I'm ready to give up. How can I do this meeting my power requirements, the Fio's limited ADC range, while using a microphone (not a 1/8" jack!).
I am proficient in coding for the Arduino, and I have all the other circuitry working. I just need a means of making collecting and analyzing the audio data so I can use it with the Audio circuit. I have no problem buying parts if needed.
I will appreciate any help I can get!
