Hi all. The real title of this topic should be: Arduino library to decode syma transmitters, but my intent is to provide a very quick and cheap way to build RC things (cars, quads, robots, ...) without losing time building a professional remote control system.
Advantages: - very quick and cheap - NO lag (it's 2.4ghz but it's NOT wifi!) - great range (even greater with transmitter mod (http://www.instructables.com/id/Quadcopter-Range-Hack/) and NRF24L01+ sma version (http://www.banggood.com/NRF24L01-Wireless-Transceiver-Module-SMA-Antenna-MCU-Arduino-p-80577.html) - auto frequency selection and frequency hopping in order to have multiple projects running at the same time without disturbing each other - 4 axis and multiple buttons
Required hardware: - an Arduino - a syma remote controller (http://www.gearbest.com/rc-quadcopter-parts/pp_193065.html?wid=1, 10$ at the moment) - a NRF24L01*+* chip (http://www.gearbest.com/transmitters-receivers-module/pp_218375.html, 1$ at the moment)
