ULN2003 + BYJ48 + Leonardo Micro = how to set it all up
2017-03-20 23:23:24
I got really annoying question for todays morning.
I got a stepper motor BYJ48 connected to ULN2003 picture.
Moreover I got a Leonardo Micro Pro
Micro PRO
and pontenciometer. Nothing except Stepper and ULN2003 is connected.
My question is: how to connect it all (which pin to which, how about battery, and the potenciometer?)
I got a picture of everyhing and I really appreaciate your help. I need a code also.
The Arduino has a stepper library: Arduino Stepper Reference
Start with this great tutorial: Adafruit Stepper Tutorial
you probably want to check the schematic first. but it seems to be a simple two winding, 5/6 wire motor. so the simplest is to set up individual IN1..4 pins high and see it spinning.
you can test by connecting IN1..4 to Vcc via a resistor.
Once you have done that, write your code to drive it in whole steps, or via micro stepping.
