Arduino and Vernier Sensors


Vernier Software & Technology has always supported hands-on, do-it-yourself projects for students (and teachers). The availability of very inexpensive, easy-to-program microcontrollers, like the Arduino, make projects easy and affordable.

This guide to using Vernier sensors with Arduino is meant to help you with the connections, programming, and calibration of our sensors. It also should give you a start on some entertaining and educational projects. It includes many Arduino sketches (programs). These are meant to be starting points for your projects. They can save you a lot of time because they already contain the code to read the Vernier sensors. They also can help you learn how to use the Vernier Digital Control Unit to control motors of all kinds. The programs were intentionally kept simple, so that you can easily see what they do, without getting overwhelmed with complex features.


If you do not have a Vernier Arduino Interface Shield, you can still connect Vernier sensors to an Arduino with a breadboard and our Protoboard Adapters. Refer to the Sensor Pinouts when making your connections.


All of Vernier’s Arduino sketches are available to view, download, or fork on GitHub.
