Rev.2.0.0 - Rewired for full piezo circuit control
...
- Moved ERR_LED to Pin2/PD4; replaced with V_FOL_PWM on Pin1/OC2B to
adjust Voltage Follower level

comparator threshold voltage reference
- Attached series resistor ladder to gain amp voltage divider,changed
all resistor values to 470R, allowing a gain of 5 values: 10x, 6.8x,
5.15x, 4.15x, and 3.47x
