  • Got the sensor resistance converted to voltage. A 1k ohm resistor seems to work best, since I want most of the sensitivity to be light pressure. Next, build a circuit with three channels that connects to the Phidgets voltage sensor. The only thing I’m wondering is if I’ll get the resolution with the voltage range I’m getting – Zero to about 2.5 volts. I’m estimating that I should get about 1500 – 3000 steps out of that, assuming -30v to +30v is resolved to a (unsigned?) 16-bit int.
