Klemen Kozjek, Aleš Jaklič · Repository of the University of Ljubljana (University of Ljubljana) · 2015
We designed hardware and software for simple multichannel RC Servo Controller for smartphones and tablets running Android OS. The design is based on audio subsystem of a smartphone, pulse position modulation, and hardware decoding of the modulated audio signal. It also leverages the touch screen as GUI. The cost of the decoding hardware is in the range of few Euros and can be simply made using basic electronics tools.
