Alternately, the reset pin may be connected to any unused pin on your Teensy, if you want a hardware connection that resets the LCD to its default state. Before initializing the LCD, output a low to reset the LCD, then high to allow it to operate. For example: ...

Achess clock, or similar countdown/countup timer clock. You may need to add an RTC clock chip to the board, but this is not particularly difficult. Optionally, you might want to add a second momentary contact switch, so that each player has one. Now this would be an interesting and ...
