Nice video with good info, thanks and keep up the good work.

I am building a custom heater control for an old classic vehicle. Using a dc motor actuator found on most simple HVAC systems, this is a brushed motor at 12 volts +, but is geared to a pot to provide feedback for position control. Move a lever or pot on the dash, and the motor moves a little or sweeps from stop to stop. A simple system to control a heater door with using a bunch of electronics. Do you have an idea? Thanks for the video. ASE Master Tech / Retired

thanks I will do the same and tell you how it goes. is for a remote control post apocalyptic car
-
How to control this with digital signals from second arduino.
-
I want to run this servo motor by coding not by external potientometer please help me I have a project in which I am going to use it
-
I intend to operate a valve with Dc motor, I have done some testings and valves do open and close perfectly but I need it to work with DS18S20
-
Hi it is possible if i change the dc motor encoder with dc motor without encoder? The code will be the same??
-
What is your input for current angle and required angle? Where on the circuit is that coming from?
-
Hi Is it possible to modify code and turn motor based on temperature inputs?
-
Bro I need circuit diagram..plzz
-
I can not see the hardware schematic I think link is broken.

Don't use potentiometer, use motors inbuilt encoders to get precise movements. (use a PID algorithm).
