Simple PID control intro device

Arduino TeamDecember 3rd, 2018

You may have come across the term “PID control,” and while this proportional-integral-derivative control method does a great job of smoothing out oscillations, where does one get started? 

One solution would be Mr Innovative’s demo device, showcased in the video below. In it, a DC gear motor is able to smoothly rotate an arrow overlaid on a protractor by a certain number of degrees.

Input is via a Bluetooth smartphone interface, and an encoder is used for feedback to the commanding Arduino Uno. Everything is fastened together by 3D-printed parts, and if you’d like to try your own PID experiment, code and print files are linked in the video description.

    Firstly you can improve it by continuing the description you started giving, there is nothing at all wrong with your narration. I learned a lot from the period when you were talking and very little when you just put the music on.
    You showed a board being made, is it possible to get one of these boards or at least the fritzing file so I could get one made?
    also is it possible to get the 3d printer files?
    thanks. keep up the narration.

    Well done! Also, your communication is at least as good as my teachers in college. Please continue to share your projects.
