Hi guys! =)
Okay I have a 3.3v output from an arduino and I want to programmatically control this voltage between 1.2v to 3v to control the speed a motor via a motor controller. I did some research and came across creating a variable voltage divider using a digital potentiometer. Whilst doing some more searching I came across variable voltage regulators. Are the regulators just a potentiometer inside a regulator?
Which would be better to use in my situation and what sort of potentiometer or regulator should I use?
Can anyone suggest a good product to use?
Thanks in advance!
