I had an issue where the 28BYJ-48 with ULN2003 (as pictured here: [Controlling a stepper motor using Stepper library - Photon crashes with 'usage fault'](https://community.particle.io/t/controlling-a-stepper-motor-using-stepper-library-photon-crashes-with-usage-fault/17663/13)) only turned in one direction. I found this topic on the Arduino forum that suggested swapping the middle two pins which got it working perfectly (on 4.8v USB power off VIN of the Photon).

Just in case someone else stumbles across a similar problem!
