Arduino PulseIn:How to Measure input signal periods using an Arduino. There are two Pulse-In functions. Which one you should use for best accuracy? Find out why there two functions, why interrupts must be on for one and off for the other, and why your measurement might be inaccurate. ...

Returns data from an RC Receiver using the digital IO ports of an Arduino. When a standard RC Receiver's output is connected to an interrupt supported pin on the Arduino, this block uses interrupts to measure the width of the servo pulse. Usually servo pulses range from 1000 to 2000 ...
