This is a digital car gauge based on the OBDuino Arduino code. It uses a modified bluetooth EL327 adapter and an Arduino.
You can find the arduino code on my website here:

How did u hard wired the ELM 327 with arduino
I really like your project and would like to something similar. This to me is a proof of concept, because I understand much of what you are doing but much I do not. 1 question 🙂 what resources did you use to learn how to build this. How did you learn how to do this yourself? thanks, great job
Very Neatly done!
clean man ! 🙂
cool but make it do more than the ap..u have those temp sensors, add auto climate either use a little linear actuator , make a digital circut to switch between resistor banks
Nice project ! Where did you get 1602 lcd board?
Could I get the miliage information ?
Hi. What pin do you disconnect with relay on ELM???
Nice, need diy steps or instructions on how to do and set it up
Hi Justin!
Congrats for your amazing job! I'm interested to develop a similar project for my car using obd II elm327 bt dongle and arduino.
Where can I find a comprehensive wiring diagram and/or instructions to how hack the bluetooth dongle hooking it up to arduino?
Thanks so much!
Ciao!
what kind of arduino did you use? I have never used one before.
cool clean miata, its simple but stylish, I like it!
