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)

At the heart of the Stepoko is an Uno compatible ATmega328p

Piezo Vibration Sensor - Small Vertical Shipping:1 day but you can wire upThe 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
