DIY: Regulate VREF (Mini CNC Machine)
First Published in 22 ago. 2015 on my previous Youtube Channel
Regulate VREF for the New Pololu Driver A4988 RED for the CD/DVD rom Stepper Motor NMB PL15S – 020
For this stepper motor to control it with arduino uno r3, Gshield Protoneer version 3.00 and Pololu Driver A4988 red you need to regulate the VREF to 0, 20
In a previous video about my first attempt with arduino uno r3, I explained how to calculate the VREF with a simple mathematical ecuasion.
Thx for watching !
