Hi Mathew, Great article on LED’s, but I have one question, not being a ‘Sparky’ or wiring knowledgeable, it’s where you say ‘Then if you need more than 3 LEDs in the model, you can connect 3 more 3V LEDs in series (or a series circuit), then connect this series circuit in parallel with the first series circuit.’ Driving a Bipolar Stepper Motor with Arduino and ULN2803AG Good stuff, Shane! Thanks for the video! But yes, out of your three motors this particular setup was actually devised to be used with your smallest one Additionally, the small ones have only 20 steps per revolution whereas the larger motor you used most likely has 200, so you were absolutely correct with the delay change – it would have been 10 times slower than intended if you didn’t ...
