Quite a while ago I saw a 0.96″ OLED display for sale on Ebay for £4.45 and thought it sounded a good price. It arrived and I was quite busy at the time so it went into my modules drawer.
The other day I was tidying up and ordering my electronics and rediscovered it. So today I decided to see if I could get it to work with my Arduino Duemilanove.
Firstly, wiring. The display has 4 pins, 5v, GND, SCL and SDA (quite hard to see in this pic).
The Arduino’s SCL pin is analog 5 and SDA is analog 4.
Once you’ve wired it up, you need to install the libraries that are needed to control the display. These are on Adafruit’s GitHub here:
(Installation instructions in the README)
Now reopen the Arduino IDE and open the example file located in Examples/Adafruit_SSD1306/ssd1306_128x64_i2c (if it’s not there look in your sketchbook/libraries
Change line 61 to say:
If you now look at your display it should go through a sequence of graphic and text based displays.
