Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Connecting esp32 to a bluetooth ODB2sensor
Coding: You'll need to communicate with the OBD2 scanner somehow. Check out the ELMduino library which is designed to talk to the OBD2 scanner via ELM327 Bluetooth adapters. You might need to read through the library documentation and understand how to send/receive data.

Identify rx/TX on an elm327
I believe its much harder to get data off of the elm327 via serial, there is a very easy example sketch on the ELMDuino library page on github. Here.

OBD-II Vehicle data port to ESP32 anyone?
Not quite sure why you'd want to modify the reader. There's a boatload of WiFi ELM327 dongles for under $20 on Amazon. You can tap a 5V line to power the ESP32 in the vehicle for something permanent or use a power port for something portable. If you want to easy mode it, use something like the Elmduino library.

Mini OBDII tachometer i made
I used this library. 99% of the code was already there. All I had to do was find the UDID number for my bluetooth scanner the esp32 would connect automatically. Now using the library I can pull just about any information from the OBDII port.

OBD2 -> LED Matrix Help
So parsing out the ODB2, that device is an ELM based device, so this should make your life easier: https://github.com/PowerBroker2/ELMduino

Arduino HUD for my Charger
Also, check out the code AND 3d print files here to make one yourself! If you want to make a different Arduino car-hacking project, be sure to check out my car-hacking library ELMduino!

Raspberry Pi OBD GUI ?
This is a newer arduino library for interacting with cheapo ELM327 based devices https://github.com/PowerBroker2/ELMduino. I chopped up one of my OBD2 elm devices that was having bluetooth probs and hooked it via serial to an old arduino uno I had laying about. I got his software_serial demo to work, shows live RPM data. The hardest part was finding the serial lines in the ELM unit. If you've got an arduino based device with bluetooth then it should be snap.

OBD2 software for renault (like Forscan)
If you have elm 327 based adapter, then you can use DDT4ALL or PyREN. Both have the same functionality as original Renault diag (Renault CLIP).
What are some alternatives?
ELM327-emulator - ELM327 Emulator for testing software interfacing OBDII via ELM327 adapter supporting multi-ECU simulation
AndrOBD - Android OBD diagnostics with any ELM327 adapter
