correct a few derps with missing resistors
correct encoder pushbutton
add i2c pullup resistors
move some 32u4 pins to more accessible ones, supported by the arduino micro bootloader
wire the 5v led to the builtin led on 32u4
remove the ad737, move the a non-inverting summer circuit (wave+offset) with a peak finder to get the peak of the wave no matter the offset condition
* shrink down to 11*8.5cm
* Correct a few derps
* Cumulative of caps changes on teensy and 32u4, add writes to output type choosing
* Ignore overlap on transistors
* Ignore AirWire on U4 and U3 (PRME15005) since the pins are shorted
Peak detector needed external impedance decoupling and would not have worked when the offset was different from 0 or when the amplification lead the OpAmps into saturation
AD737 is a True-RMS-to-DC converter, which works perfectly for this situation, coming at just 1$ more than an AD8034 IC
