I've programmed a Teensy for 3 things. One was as an example for my son to modify and extend for a senior design project (a home monitoring system). The second was a USB HID for arbitrary button inputs, with the beginnings of support for a rotary-encoder-based control knob. Finally, with an audio output peripheral as a museum exhibit controller that waits for a button to be pressed then plays a message and enables a motor to spin a turntable.

I also planned a programmable thermostat, but I could never get the built-in temperature sensor to give me reasonable data, and I wasn't motivated enough to connect an external sensor.
