Project Summary

We wanted to create a rotary table to show off some smaller parts or 3d prints we build to up our production value a bit.

Circuit Design

Source Code

 This code uses the AccelStepper Library it, you will need to download and install it for this code to work.

#include 

AccelStepper stepper(1, 9, 8);

int potPin = 0;

void setup()
{  
  stepper.setMaxSpeed(3000);
  stepper.setAcceleration(1000);
}

void loop()
{

int potVal = map(analogRead(potPin), 0, 1023, -511, 511);  

  if(potVal <= 11 && potVal >= -1) {
    potVal = 0;
  }
  
    stepper.move(potVal);
  stepper.run();
}

• 10mm Ball Bearings
• 8 Inch Mirror (You can get these at craft stores for around $3 for a single one)

Addition of a 3d Printed Knob

To add some extra finish and ease of use I designed a knob for the potentiometer we used in this build.
