How about making an amber and green LED alternately flash on your cool new widget you are building with a microcontroller?
Testing so a robotic control program will know that one of its sensors has tripped. (it has hit the wall, and maybe should reverse for a bit.)
This type of activity is usually reserved for hardware programming / embedded systems. It's what makes your keyboard work with a single chip and an embedded program to convert switch closures into a stream of characters the computer can use as input.
