How would i go about comapring two voltages (milivolt range) from different sources and based on the result turn a servo on way or the other?
The idea is to have 2 microphones pointing 180 degrees away from each other. If a noise is louder on one side i need to turn both mics so that the sound level is even (within a tolerance i guess)
To visualize this think of how your ears work. You hear a sound on one side then turn your head to look directly at it
I guess some kind of opamp setup would be needed? or could i just use analog inputs on the panda II and compare in code?
All thoughts greatly recieved
