Pulse watcher

Pulse watcher,
for monitoring the control pulse from receiver.

R/C receiver controls servo and ESC with sending certain length of pulse. In a representative position, 1550us at neutral position, 1100us at minimum pulse, and 2000us at max. Here, I tried to monitor the length fo the pulse from a receiver.

How it works;
On 1sec intervals, it measures a pulse length and display on LCD.
