The Pololu Zumo 32U4 robot is a versatile tracked robot based on the Arduino-compatible ATmega32U4 MCU. It includes two 100:1 HP micro metal gearmotors along with integrated dual motor drivers, an LCD, quadrature encoders, line sensors, side and front proximity sensors for detecting objects, and a full IMU for detecting impacts and tracking orientation. The low-profile robot is less than 10 cm × 10 cm—small enough to qualify for Mini Sumo. No soldering or assembly is required; just add 4 AA batteries and a USB cable and your Zumo is ready for programming.

This 12-inch (30-cm) cable has 28 AWG wires and a 3-pin female JST ZH-style connector that mates with the 3-pin connector on Sharp GP2Y0A51 analog distance sensors. The other ends of the wires are unterminated; they can be cut to length to match your application. The wire color scheme matches the Sharp distance sensor pinout: red for power, black for ground, and white for signal.

This electromagnetic transducer is a compact way to add sound to your embedded project: just supply it with a PWM signal at 3 V to 7 V and it will produce sound at the frequency of the supplied signal from an opening on the side. Since the 70 mA maximum current draw is higher than what can be supplied by a typical microcontroller I/O pin, you will probably want to control it with a suitable driver, such as a small MOSFET.
