Piezo Vibration Sensor - Small Vertical Shipping:1 day It's a clever electromechanical box

It's a clever electromechanical box that turns itself off after you've turned it on

At the heart of the Stepoko is an Uno compatible ATmega328p

along with pushbuttons

but you can wire up a console cable for direct-connection to the module if you want to send commands from a terminal (great for testing and tweaking)

Piezo Vibration Sensor - Small Vertical Shipping:1 day It's a clever electromechanical boxThe Minisense 100 from Measurement Specialties is a low cost cantilever type vibration sensor loaded by a mass to offer high sensitivity at low frequencies. Useful for detecting vibration and \'tap\' inputs from a user. A small AC and large voltage (up to + 90V) is created when the film moves back an forth. A simple resistor should get the voltage down to ADC levels. Can also be used for impact sensing or a flexible switch. Comes with solder pins that
