I'm using FS-CT6B transmitter with R6B receiver. I have seen many code examples and tutorials for reading PPM output from R6B using Arduino Uno. In some of them, only one pin is used (external interrupt pin or any other pins) to read all channels of R6B receiver. If only one pin is used to read all channels, where to connect CH1,CH2...CH6 pins of receiver. The question and the concept might be simple and silly, but I could not get answer for my doubt in any sites. So I hope I'll get a good answer from this site. I'm completely new to RC world so please help me out.
