@zander and @daves Thanks for the replies. I'm going to use 9V batteries with a 2.1mm plug for general testing and a regulated power supply of 5V for ...

@zander Thanks for the reply Ron. I agree with you that the Arduino won't pull any more current than it needs so 3A is OK. I was hoping to find out th...

@will I plugged the UNO into my PC and it powered right up on 6V for the stepper. I took a video of the stepper working but it is >10MB. I'll...

@will Above is the CWD I am attempting to wire up between the Arduino and the A4988 as per the Dronebot Workshop video. It shows no separate powe...

@will I will connect the stepper as you suggest: A+ to 1A, B+ to 1B, A- to 2A, and B- to 2B for consistency. I found that I had jumpered the Reset and...

There are lots of ways to extend the reach of an Arduino microcontroller. For instance, each stepper has two coil circuits A and B. If I insert a SPDT...

@will There are 54 steppers to control so I need some logic to select the stepper for the controller to run. I am trying to engineer sending the contr...
