I have built a marshmallow cannon that I would like to control remotely with a 2.4GHz remote. I have several questions:
How do I connect the receiver to the arduino board (I am using Leonardo)?
How do I read a specific chanel on the receiver to activate the solenoid on the valve used to launch the marshmallows?
I am planning to use a small relay and the elctronics after the arduino is not an issue.
What I have not figured yet is: 1) the connection between arduino and RF receiver and 2) the code to read that and send a digital signal to the solenoid.
I really hope that I can get help here!!.
Thanks in advance
What receiver specifically?
This sounds like a job for a plain simple RC control system. Unless you have some particular reason for wanting to develop your own microcontroller based solution, I don't see any need for an Arduino here.
got any pictures of the cannon ?
it would be neat to look at while we wait for you to post a link to the transmitter
The receiver is a Futaba FP-R127DF.
I will post picture shortly ( I do not have any right now).
I need to go through an arduino because the Pololu motor controllers I have do not 'do' 2.4GHz or RF well (Item #1373). Also, I would like to have the arduino (later improvement on this project) calculate a 'firing' solution and fire automatically the marshmallow.
You can find all of your questions on interfacing with RC recievers (etc.) at http://rcarduino.blogspot.com/, notably http://rcarduino.blogspot.com/2012/11/how-to-read-rc-channels-rcarduinofastlib.html
Hi,
This post is a better starting point for reading a single channel -
For a very simple project thats just going to use one channel and if your not interested in learning how things work you could just use the Arduino pulseIn function.
