I am making some led dice with an attiny85 (programed via arduino) and I need a sensor to detect when the die is shook. I need the sensor to be small, cheep (under $5 or homemade), and take 2 or less input (analog or digital) pins to use. Would a tilt sensor work? I have found examples online on how to use a tilt sensor to detect shaking with arduino, but none of the codes do what I want. I want to know when the die is shaken a medium to large amount (like when you shake something in your hand). Also, another forum (Simple "Shake" Sensor? - SparkFun Electronics ) suggested a piezo with a weight attached, but it did not explain how the wiring or code would work.
Something like this? Tilt Sensor - AT407 - SEN-10289 - SparkFun Electronics. Or a tri- axial accelerometer.

Maybe, but I don't get how you could detect shaking with it.
Maybe you could make one with a ball bearing (that conducts), some wire, and a small section of straw. Put both wires in one end of the straw so that when the ball comes in contact with them, it conducts.

It would be identical to using a push button switch and watching for someone rapidly pressing/depressing the button.
Thanks, but I decided to make my own sensor based off of the adafruit shake sensor with hot glue, solder, a spring, and the lead of a resistor.
