I am 100% new to all of this, although I am a software developer and understand coding. I am trying to follow this guys video, but he does not talk about what he did in the Arduino at all. Any help at all would be appreciated.
I assume from his schematic I have a resistor in between the Arduino and the feed to the joystick wires, and a capacitor from negative to the same side as the resistor as the Arduino. Would love a confirmation on that. I have looked at several videos on doing this and it seems the 2.5v for neutral and + or - 1 volt for forward and reverse. Once my 12v batteries are charged I can start seeing what works and what the volts are on the joystick.
But I need an idea of what programing he did in the Arduino to handle the RC input and send a signal to the wire from the joystick to simulate it and move the wheel chair.
There are lots of projects that read signals from an RC receiver. Google can probably find a few. Perhaps even one for your particular brand of radio (although there aren't many differences between brands).
When watching the video, click on the Youtube icon at the bottom right corner. The Youtube page has a link to the source code on github. And more discussion about how it works are in the comments section.
Thanks, I do not know how I missed that. That is what I WAS looking for. Sadly I pulled my $50 chair apart and it is a lot older and has a 2 (x and y axis) wire joystick and neutral is 10v so I would have to step up the 5v from the Arduino and at that point I chose to order a Sabertooth 2x32 to control the motors, the motors on the chair were good. Plus the controller on the chair is bad, trying to operate both wheels cause it to code out. But each motor works good.
I saw videos on that, but I am actually going to take this and make a RC mower to mow steep slopes to steep to push a mower on, or even drive a tractor up. So I thought I needed something a little more solid. Because of issues I found when I finally got time to tear into the chair today I am going with a sabertooth 2x32, since it will control both motors and the brakes. Hated spending that money but the controller in my $50 chair turns out to have issues. My main goal was the motors and frame to cut up and work with, the way it was wired turned out well as I can reuse most of the harness. But on a good note my Arduino starter kit showed up, so will play with that and probably incorporate distance sensors into my safety design, plus I was shocked at how cheap sensors and stuff are.
