Arduino OLED Gauges

« Back to RetroJDM's Arduino projects

A GPS gauge cluster using an Arduino MEGA 2560, Adafruit Ultimate GPS Logger Shield, and multiple 4D Systems uOLED-160-G2 displays.

Cool, but why?

I wanted to create a GPS speedo for a friend with a boat. Of course, I got carried away and decided to make a multi-gauge cluster controlled by an Arduino MEGA 2560.

Here's a working javascript mock-up I made while waiting for the displays etc in the post:

The idea here, is to have a gauge cluster controlled by a central controller. That way I can save on parts, and have a colour change (or from analog to digital) happen on all displays simultaneously when I change just one.

Features

You can enter a menu on each gauge to enable/disable the screens it cycles through.

The settings are saved to EEPROM, and re-loaded at power-up.

Screens available (in either digital or analog styles):

• Clock
• Compass
• GPS Home (can be set, then an arrow always points there with the distance shown)
• GPS Location (shows latitude/longitude)
• Speedo (MPH)
• Speedo (KM/H)
• Speedo (Knots)
• Tacho

To Do / What's Next?

I still need to mount it in a car/boat and hook the tacho up via an optocoupler (so I don't fry the Arduino).

I'd eventually like to connect an Air/Fuel Ratio (AFR) gauge and Throttle Position Sensor (TPS).Then I'd have it show a live graph and do data logging. That should make tuning the Webers in my RA28 a bit easier.

I can see myself going crazy with it, and adding all sorts of gauges: Volts, Water Temp, Oil Pressure, etc...
