Prototype: Keyboard interface and communicationDate of completion: 03/2007
This prototype was created for the project "Secret under my skin", although it was eventually not included in the final exhibition. The idea is to:
1) take a keyboard, capture its output with a microcontroller (ATmega32),
2) store the typed character and optionally echo it on a LCD (for feedback to the typist),
3) after typing/storing, pressing a key will trigger the microcontroller to output the message,
4) a second microcontroller receives the message from the first and shows it on a LED display.
The original idea of the prototype was to learn a number of things such as: capturing keyboard signals, interfacing the ATmega32 with a LCD, sending/receiving PWM signals, and displaying messages on a custom LED display.
