Dot/Bar Display Driver - LM3914 (Linear)  /COM-12694

This is the LM3914 Dot/Bar display analog-controlled LED driver that uses an alinear output scale. With this driver all it takes is a single, analog signal to drive a string of 10+ LEDs, which can be configured into either bar mode (where all LEDs below a certain point turn on) or dot mode (with only a single LED on at a time). Hook them up properly, and you can create all sorts of nifty multi-LED displays.

Piezo Vibration Sensor - Large with Mass  /SEN-09197

This basic piezo sensor from Measurement Specialties is often used for flex, touch, vibration and shock measurements. A small AC and large voltage (up to +/-90V) is created when the film moves back and forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch.
