Abstract: 

Why go slow? We need to take pictures at very slow speeds and at a continuous rate using a hyperspectral camera! With the old electronics board, this was not possible, but the new one works amazing!

Objective: 

Rotate the stepper motor at very slow and steady rates to allow the camera to take pictures. 

Materials and Methods: 

Using the Sparkfun’s EasyDriver Stepper Motor Driver, we are going to drive the stepper motors for this project. We were previously using Adafruit’s TB6612 Stepper Motor Driver but it was not giving us the performance that wee need.  Here is the wired up motor driver:

Results:

Using Sparkfun’s board we are able to achieve the results that we wanted. We are going use the new board instead. It works great at very low speeds and is very steady.
