I have also tested that while playing with knobs on the transmitter I get either -4 or +4 Volts on the receiver (receiver has of course two output lines - forward/backward and left/right).[...] What I would like to achieve is to detect this +/- 4V signal on two different input ports of the uC and handle those events with software.
Soeren: i understand +5V, GND and Out have to be plugged to the uC as +5V, GND and signal pins respectively, but what is "In" exactly? From the receiver I have two wires commig out, where should I connect the other one?
I'm sorry, I know this is an extremely lame question but IC schematics simply scare me (especially the open ones )
I would also greatly appreciate any good and complete noob tutorial on understanding schematics, to be able to read things like you've posted and in future maybe even understand how they work
One more question: isn't the receiver sending pwm signal to the uC? If so, then I can imagine that handling the uC pin's high state interrupt wouldn't be enough to have a fluent speed control.If the receiver is sending pulse signals, then servo movement would be rather jumpy, am I right?
