So I just finished my microcontroller lab for the semester and I'm pretty motivated to keep doing work with them. I was gonna recontent my clock but I decided I want to put a two line LCD in that spot and wire it up to a microcontroller(probably a PIC16F874.) On one side I would have the time, and on the other I'm thinking of displaying two vitals that can be changed to whatever is available and desireable.
My question is, what do you guys think would be the best approach for this? Tap into some sensors on the car or read up on ODBII and tap into that? I think ODBII might require more programming, but easier as far as plug n playability.
The stuff I display isn't that important to me. This is more to keep myself occupied and do something different(Although a voltmeter is a must, no more running around with a dying alternator for this guy.)
Thanks,
Chris
