I'd like to read the PWM servo signals coming out of my receiver (Spektrum Ar600) with an Arduino UNO board and mirror them back out to the servo (so I can eventually add some control in the future). Creating PWM signals with the Arduino appears straight forward, but reading them has not been so.. All official Arduinos run on 5 volts, which for a long time was the 'standard' voltage for hobbyist electronics and microcontrollers.
