KermMartian | Arduino to TI-84+ Linking @KermMartian | Uploaded 14 years ago | Updated 10 hours ago
Source: http://cemete.ch/t4771 | As a proof-of-concept and a step towards development of the Ultimate Calculator 3, I implemented TI linking routines on an Arduino Duemillanove. I connected a thumb-slide joystick to the calculator, using the Arduino to emulate the calculator's remote keypress protocol. The LED indicates link activity.
