We recently updated the Arduino™ section of our website. It has instructional material to lead students through a short course on Arduino terminology, an introduction to how sensors work, and sample projects. We have also posted sample code to read from over 80 Vernier sensors, which can be connected via the Vernier Arduino Interface Shield. This includes recent updates to the code to auto-ID on any Vernier BTA (analog) sensor, run a servo motor, and control a Vernier Digital Control Unit. We also have several sample projects that students will find interesting, including a laser pointer aimed with a servo motor, alarm systems based on motion detection, and a system to drive a pendulum with an electromagnet to keep it swinging indefinitely.
