Hi everyone!

I'd like to share a project that I started recently with my Speeduino install. I made an OLED display gauge based on an Arduino Nano board. Here's the Github link to the project: https://github.com/MielArrojado/speeduino-ardugauge. It also includes a demo video and screenshots of the display. The display's pages and data are customizable in code.

It's my first time posting here. Hopefully someone finds my project useful. Cheers!

Cool. I appreciate you added a bit of useful direction in your readme, so unfamiliar users can hopefully make it work for them. While most have moved to smartphones on Bluetooth for random info and logging, I'm thinking it would make a nifty system monitor with just the OLED and switch mounted in the instrument cluster. Hmm... Image

That's right PSIG! I had a few reasons for making this standalone gauge:
  • I have a custom board that fits in the Dropbear version case. The board is pretty crowded and I couldn't fit a socket for the Bluetooth module anymore. And since the enclosure is metal, I don't expect Bluetooth to work very well anyway.
  • I mainly use my phone for navigation. I thought it would be better to have a standalone gauge that you leave in your car and turns on with the ECU without user actions.
  • Don't have money to buy commercially available gauges. :(

I don't like the OLEDs, they aren't bright enough to see in sunlight.

With a teensy you have plenty of RAM and flash, I'd try a color TFT. I've been working to get one going at high speed on SAME51.

I made another one using an OLED that I still use, but now that the OLED is starting to burn in really good it's even less visible.

The new IPS TFT is 4 times as bright and shouldn't dim anywhere near as fast...

Thanks for the tip. I just ordered a ST7789. I had some issues with another TFT but I think it just got damaged. This one was $11.

I have asked you a question in the issue-section of github.

But basically, is it possible with the i2c screens to use two screens instead of one?

Having two 0,96" with a single data set each is much easier to read than a single showing up to 4 sets of data.

To add those additional sensors to the secondary s[…]

Hi PSIG, Thanks for the reply and leads to try. I[…]

Well done
