Arduino OLED Gauges
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.
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.
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):
- 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)
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...
The Arduino Library (with example).
Note: The menu's etc use a lot of SRAM. It doesn't work on an Uno. I've only tested it on an Arduino MEGA 2560 R3.
The graphics for each uOLED-160-G2 Display.
You'll need to use 4D System's Graphics Composer to put this on an uSD card in RAW format.
