Arduino OLED display
One obvious Arduino UI option that I had previously overlooked was a small OLED display device. While they have a small screen size these are inexpensive devices and easy to communicate with using the I2C 2 wire interface. Installing libraries I used the IDE library manager to look for suitable software to run an SSD1306 OLED display. I chose the Adafruit option as that included provision for a 128 x 32 device and the I2C interface. The installation prompted me to include a GFX and BusIO library as they were dependencies. I knew I wanted a GFX library to manage some basic graphics. Testing Then connected a good old basic Arduino Uno to the board using 4 jumper wires - 2 for power and the 2 for the I2C interface. Then I loaded the appropriate Adafruit supplied example program and watched it happily run through a great demonstration of the display's capabilities. The library supports a wide range of graphics drawing options alongside simple text. Next steps The next step for this lit...
