Arduino is an open source hardware platform that allows designers, developers, and anyone to create amazing things with a little bit of electronic know-how.
4D-Systems make a line of small OLED Display screens that work great with the Arduino. I created my own Arduino 4D Systems OLED Library for this piece of hardware though. This Library would help me, and anyone else looking to harness the power of these small OLED screens. It covers all the primary screen drawing functions, placing text and doing SD memory card operations. Once added and compiled in your Arduino IED you can initialize
OLED myOLED = OLED(7,8,2500,57600);
myOLED.DrawLine(ax, ay, bx, by, color );
What's been really cool now is seeing that other people are using it and developing from this base. The link below is to my github repository as well as someones cleaver use of my library to make a small Oscilloscope.
