Re: Dart linear actuator programming and the 10 turn potentiometer

If you don't have documentation on the item, connect the sensors and run it to one end, measure the voltage and counts, then drive it to the other end and count again. Divide these by the length of the stroke to get the volts per inch and counts per inch. Then, do a few tests, having the robot drive to pre-selected points (e.g. 3 inches from the end), and measure (with a ruler) to see if it is linear (that is, hits the right spot).
