So, i've "soldered" with a hot knife a wire i've ripped from a stepper motor, and wanted to know if the connection was fine. in theory i could connect one end to a digital pin and the other to another, digitalwrite though the first pin and digitalRead trough the second one right?
im not sure, ive tried to test it, with a led, but it wouldnt even light up, shouldnt the input pin be soakin up the energy as the GND pins would? if not, what's the difference on a pushbutton going to an input and a led being connected to it?
Im sure this is probably an stupid misconception of mine.
I was also thinking i could use the stepper without a microcontroller, shifting the pinmode from input to output to switch the current as the controller would, is that possible?
Thanks for dealing with my incompetence, im new to this, but i want to know why is this failing
