Hi All,
I am trying to build an Arduino based R/C transmitter for model aircraft. Got everything working, but have a small problem with the control pots on the sticks. They are 5k pots, but only a small range of the pot is used. When I read them with the Arduino I typically get values between ~400 and ~620, so a range of only about 220. The adcs on the Arduino are 10 bit resolution, so can theoretically measure from 0 to 1023. I can do some software trickery with multiple reads an...
