OBDuino working with ELM327 (pix + movie)
 
Yesterday I made my first real test with the OBDuino connected to my car, and it worked :)

Here is a picture at idle, note that the display is in L/h because speed is 0.

I also made a small movie, but in my code I had a problem with a value being signed so sometimes the fuel display goes negative (I corrected it in the trunk code).

Unfortunatly it seems google resized the movie to 320x240 :( and I was taking it with my digital camera while driving so quality is not very good, but at least it shows you the thing. I display fuel consumption, speed, RPM, load.

Nice! I love the low quality background music.

Thanks, and sorry for the music, this was the radio but the volume was low, I didn't know we would hear it, I should remove it from the video :)

I would make one of these with a larger display, to be able to look at six or eight gauges at a time. That would be sweet. I think you guys are onto something here. Good luck and keep us posted.

I added menu configuration, you can now configure LCD contrast and if you want metric unit or imperial.

I also added "virtual" screens, there is 3 screens, each displaying 4 infos, you rotate through them by pressing a button. It makes 12 infos available quickly. I will add them in the configuration too.

Buttons act like this:
Code:

        realtime display      menu display
LEFT    rotate screen        decrease, select NO
MIDDLE  go into menu          apply and go to next item
RIGHT  rotate brightness    increase, select YES

BTW here is my ELM interface:

hello guys....

i'm looking for a display to show how much gasoline my car is using...

i built the elm 327 scanner last week and i think that this will work perfectly....

so, where i can get the projects to build a display like this?

thanks.

marcelo.

If you have a serial ELM327 interface, I think you just have to plug it to the serial plug of an Arduino clone. I don't know if you need a straight cable or a cross one however!

If you have a USB version you will have to wire pin 16 of the ELM327 to pin 1 (TX) of the Arduino and pin 17 of the ELM327 to pin 0 (RX) of the Arduino.

Project is described here
