GoIOLink release candidate 1

Introduction

GoIOLink is the flagship component of a project I call VernierPiLink which seeks to provide a variety of Vernier-sensor-Raspberry-Pi integration resources.  It relies on VS&T’s Go!Link USB adapter to perform the physical connection between an analog Vernier sensor and the Raspberry Pi.  On the software side, I am using the Go! I/O software development kit also from VS&T and the Wolfram Language which comes free (for non-commercial use) on the Raspberry Pi.

Using Vernier LabQuest sensors on the Raspberry Pi

In the previous iteration of my website, I had some details about installing the Vernier Go software development kit on the Raspberry Pi and then using Mathematica to visualize the results.  Here is an updated set of instructions which is a little more straightforward.

This post is a reprint of an article I wrote on my earlier website.  I’ve tried to update the links and images, but may have missed a few.

I recently purchased the camera that attaches to a Raspberry Pi and thought about how one might be able to make a spectrophotometer using the camera as a ccd-like detector. This work is still in progress, but with relatively few steps, I was able to get an instrument up and running (and even calibrated – sort of).
