I'll try and get some pics of this project tomorrow for you guys then, it was supposed to be a bed bug trap but honestly it was all my partners idea and he is seriously one helluva an idiot. Looking for any idea as his "million dollar idea".
What I am wondering automotive wise with the arduino is could I tap into various sending units on my vehicle and have an LCD to display actual values.
For instance, my oil pressure gauge is a dummy gauge, it only displays normal, low or high. If the PCM detects a signal above X then it displays normal etc no matter how the pressure changes.
I'd like to get the signal directly from the sending unit and have live values of things such as temp, oil pressure and such.
The biggest problem I would see is determining the scale as I don't know what voltage values correspond to what pressure/temp.
