Hello,
I have been reading a lot about Arduino and would love to use it to tackle my current project.
Just looking to get some starting tips or advice on how to go about this, or if it can even be done with the Arduino.
I am trying to use my existing steering wheel controls to control my new stereo and bluetooth device. I have all the diagrams and schematics for the controls.
From my understanding all 6 buttons run off two wires, and just create a conection but each button completes it at a diffrent resistants.
For example button one is from 50-56 ohms, #2 is 140-153 ohms ..... all the way up to #6 1.94 to 2.13 kilohms. (Idle = 5.29 kilohms)
OK so what the Arduino would do (in theory) is come on, check those two ports and start watching for it to change. If it reads a change, it would check it, somehow know what button that goes with, then out port what I program on one of the out ports.
(the outport would then send a signal or complete the connection to the appropriate button on my alpine remote and change the stereo, or a button on my bluetooth device)
Make sense? I am still learning..
Any input, suggestions, links, ideas, anything would be greatly appreciated.
Thanks
