Im looking to get one of the arduino products to work on a personal project for my truck and maybe my wifes car if i can get it done.
From all the google searches and speaking with a few other developers i now have alot of options, but not clear on the best most effective route to go...
ive seen that there is a Bluetooth OBD connector that others have used with a rasberry pi, but everyone is steering me toward the arduino products, so im here to see what is available to accommodate my needs.
First off it needs to be able to run in an automotive application, mostly 12v power source..
Next i need to be able to code against a GPS to get/log point a to point b information.
Next i need to be able to code and verify that the car is actually moving at a certain speed before getting/logging the data.
If i can communicate with the bluetooth OBD connector that would be great as well as that would provide infromation that the truck is already spitting out via the port.
A plus would be the ability to connect a LCD display or connect to my aftermarket radio and display on its screen( i found a sample of this with the rasberry, thats why i mention it here)
I realize that some of these are add-ons, so what id like to know is what is the best "core" product to get that i can add on these items or one that has some already included that will get me started.
What you are talking about should be doable with an Arduino. It would probably help if you modify your original post and correct the Title to say GPS.
Whether you would be better using an RPi or an Arduino is a more difficult question. The Arduino has very limited space to store readings unless you add an SD Card. I know very little about the RPi. If there is already RPi code to read OBD data that would be a big hurdle out of the way.
There are other Threads in this Forum about reading OBD with an Arduino.
An Arduino can drive an LCD display but without knowing how the interface with the radio works I have no idea whether that could be done.
interfacing with the radio would be a bonus, not actually needed to get this project going and working.
The main things i would like to be able to do is log the miles and have the ability to notify or display(lcd) that its time to do something at certain interval.
As for the speed, its was just a thought on how to start the monitoring, but if i can wire everything to the truck, as soon as it loads, upon starting the truck, then it can start logging the mileage.
