I used to have a tiny helicopter that came with a funky 4 channel controller. I still have many of the pieces from the helicopter (windy day :( ) including the controller.
I have recently bought an Arduino Uno and built myself a robot and was wondering if it would be possible to use the controller? Is there any way I can work out the frequency and what would I need to plug into my Uno to do it?
Based on the [ON HOLD] feedback, I'm updating with a bit more detail
So I took the controller apart, clockwise from top-left:
- Receiver in helicopter (I assume based on proximity of aerial)
- Transmitter in controller (assumed from aerial embedded in board!)
- Unknown chip behind transmitter on back of board
- Flight control chip
All assumed from no knowledge at all though.
I reckon I could probably unsolder the little receiver but I'm pretty certain I don't have the skills to solder it back on to anything! I think I found a data sheet for it too.
What would be involved in extracting and reusing a chip like that?
