I am stuck. Perhaps I'm just not using the right search terms.
I am looking for An Android app and Arduino code to use with my Arduino Yun (wifi) (or with a bluetooth shield if necessary). Want to have a simple GUI on android device to remotely control 4 arduino PWM outputs ranging from 1.5V to 3.5V.
Background: I have an electric wheelchair that I want to remotely control. I'd like to retain the original wheelchair joystick's operation, but additionally be able to control it via wifi or bluetooth with my android phone. The wheelchair joystick sends 1.5V and 3.5V, to the wheelchair's motor controller so I'll need the arduino to emulate the joystick.
Am I barking up the wrong tree or going about this in the wrong way?
Thanks in advance,
