# RC Remote control for Robomow RL series lawn mowers
## What?
Quick and dirty Arduino code to being able to control your Robomow RL series mower* with a PPM remote.
*= Tested with Robomow City 120 ~~however likely to work with RL-1000, RL-2000 RL-550, RL-850, etc. which has similar removable terminal with pigtail cable.~~ It is possible that similar mowers are compatible, however RL-500 is known to be using a different protocol.

# Necessary equipment
* PPM compatible RC transmitter an receiver (tested with a DJI Phantom MK1 remote an receiver)
* Arduino Pro micro (the code shall be portable to other Arduinos)
* Inverter to the Arduino TX line
* [PPM-reader library from Nikkilae](https://github.com/Nikkilae/PPM-reader)
# Connection info - [see schematic in cad folder](https://raw.githubusercontent.com/martonmiklos/robomow_rl_ppm_remote/master/cad/pro_micro_adapter_schematic.pdf)
* Hook your PPM receiever's output to the Arduino's pin 3
* Remove the terminal from the mower
* Connect your Serial1 port TX pin to the RX pin of mower's terminal RJ11 (pin 5)
* Power your Arduino and the mower
* Profit!
