i'm trying to think of the right way to generate a
5-10 volt 32KHz
squarewave in series with the 12v power supply for the motors, so that an
analog input can measure the amplitude of AC detected across a series
resistor. The homing switches of the motors have a capacitor that decreases
their impedance at 32KHz when they're "home".
the control circuit for the motors is a row/column array, so I also need to
lay that out.
#define NUMROWS 5
#define NUMCOLS 10
byte rows [NUMROWS] = { 13,12,11,10,9 }; // connect rows to positive
byte cols [NUMCOLS] = { 8,7,6,5,4,3,2,A2,A3,A4 }; // connect cols to
negative
