This is a test of both the air-core motor drive circuit, it's code and the OLED wiring & code all running within the Arduino Nano that's on the breadboard. There's still some hesitation in the needle at the cardinal points and it's not responding as quickly as I'd like. This may be due to my running the L293D h-bridge, the OLED and the air-core motor itself off of the 5v pin on the Arduino Nano board. Unfortunately I inadvertantly destroyed the OLED board by feeding it 5V at the 3.3v input after the power wire came loose.
