When I started playing around with embedded systems, I wanted to do something more interesting than just flashing an LED, and I spent a lot of time trying to come up with project ideas that would be useful (or at least fun) when they were done. One of the first ideas I had was to make my own version of catchphrase. Most of my extended family enjoys the game, but one problem with it is that some of the younger nephews can't understand most of the words. I thought it would be fun to create a version that they could play, and then the project grew from there.
- SPI/I2C - For interfacing with external EEPROM
- UART/USB - For connecting to computer to program EEPROM
- 5 GPIOs - Buttons
- 7-11 GPIOs - LCD, Piezo buzzer
- 4-8 kB program space (rough estimate)
