28BYJ-48 & Soft WDT Reset

[joortiz22]

I'm trying to run stepper CW then CCW but it resets before CCW command.

I've read esp8266 needs to call wifi a lot, but I don't understand how that affects this.

Error message below

What power supply are you using to power the UL2003 module?

[joortiz22]

I just read library stepper.h

Stepper - step()

This function turns the motor a specific number of steps, at a speed determined by the most recent call to setSpeed(). This function is blocking; that is, it will wait until the motor has finished moving to pass control to the next line in your sketch. For example, if you set the speed to, say, 1 RPM and called step(100) on a 100-step motor, this function would take a full minute to run. For better control, keep the speed high and only go a few steps with each call to step().

Syntax

step(steps)

Parameters

• steps: the number of steps to turn the motor. Positive integer to turn one direction, negative integer to turn the other.
