What is Arduino®

Arduino®is an open-source prototyping platform based on easy-to-use hardware and software. Arduino®

boards are able to read inputs –light-on sensor, a finger on a button or a Twitter message –and turn it into

an output –activating of a motor, turning on an LED, publishing something online. You can tell your board

what to do by sending a set of instructions to the microcontroller on the board. To do so, you use the

Arduino programming language (based on Wiring) and the Arduino®software IDE (based on Processing).

Additional shields/modules/components are required for reading a twitter message or publishing online.

Product overview

This little module adopts a flexible nano pressure-sensitive material with an ultra-thin film pad to sense

the exerted pressure. When pressure is applied to the measuring disc, the resistance of the sensor will

change. This change in resistance is converted to a varying output voltage using an additional resistor

mounted on the module to form a voltage divider.

Compatible with Arduino and Arduino compatibles!
