    Step 1

    Identify GPIOs to use on the Onion

  • 2
    Step 2

    For Inputs develop an interface suitable for the signals to read, keep in mind Onion only reads digital inputs

  • 3
    Step 3

    For outputs identify if PWM is needed, beware of maximum current to handle, relay may be more convenient than solid state devices.

Keep working on this project, its the coolest and most useful Onion project I've seen.

This project is great man, awesome work!

I have plans to turn a raspberry Pi into a Bluetooth music streamer to connect to my car CD changer port, and was hoping to be able to read the CAN bus and suchlike for getting steering wheel control to my PI.

You, sir, have just given me a million more ideas :)

Nice work! I backed the Onion guys as well and have 2 of them sitting around, been looking for something to do with them. This is some good inspiration! p.s congrats on the front page feature!

Thanks Mike! I still need to design a good PCB, add more I/Os, make it reliable, etc, etc...  but is fun to control the car with the phone...  and simple, I just run scripts from /www/cgi-bin/ and on the browser just open    (or whatever IP you get) and that's it

  Are you sure? yes | no
