2590-POLOLU Optical Encoder Pair Kit for Micro Metal Gearmotors, 5V
US$13.58
Add quadrature encoders to your LP, MP, or HP micro metal gearmotors (extended back shaft version required) with this kit consisting of two sensor boards, two 3-tooth encoder wheels, and two 5-tooth encoder wheels. The installed system does not exceed the 12 mm × 10 mm cross section of the motors and extends only 5 mm beyond the plastic motor end cap. The 3-tooth wheel provides 12 counts per revolution; using the 5-tooth wheel yields 20 counts per revolution. This version is intended for use at 5 V.

BUZ-125 Passive Buzzer
US$0.97
This passive buzzer will produce audio only when a AC signal is supplied to the device. When you apply a DC voltage, the buzzer will not generate a tone since it will require a sinusoidal wave. You can achieve this buy supply either a sine wave from a function generator or create PWM waves using a microcontroller or 555 timer. If you are looking for buzzers that make noise when a DC signal is supplied we highly recommend looking for active buzzers.
