Piezo Pickups
Piezo elements are used like a contact microphone. The material (crystal) forces electrons to move when it is shocked or vibrates. We connect two leads to it, which then can be amplified and smoothed with filters, making it more usable.
Accelerometers
Quadrature Encoder
Motors/PWM
Motors can also be controlled my the AVR. There are some extra parts involved. Foremost of course is a DC motor. It also needs a motor controller, which supplies the needed voltage and current to the motor.
LED intensity, too!
