These displays really come in handy on portable sensor projects. I used the tutorial with the Sparkfun Inventor’s Kit for Arduino to figure out the wiring.
If you want less wiring, you can now get I2C backpacks for these.
I eagerly await the day when there is a flat, flexible display screen that can be sewn into clothing.
