As I begin my journey to solve a problem I have, I want to admit that I have only taken an introductory course in electronics.
My situation ..
I need a buck converter to control the voltage to a peltier device. My problem is that all of the buck converters I have seen, have all had manual analog adjustment mechanisms.
My first need is to find out if a digital potentiometer can be attached to a standard buck converter.
I did find this post from 2016 ... https://forum.allaboutcircuits.com/threads/digital-potentiometer-and-power-supply.125512/ ... but I am not sure if a dc-dc booster is equivalent to a buck converter.
My second issue is how to convert the signals from heat sensors into a signal that is usable by the digital potentiometer.
I am thinking of using a microcontroller
So my questions are.
Can a standard buck converter be modified to accept input from a digital potentiometer?
Can a microcontroller query the heat sensors and convert that information into a usable signal for the digital potentiometer?
Any advice and guidance will be greatly appreciated.
