Connect the Direction wire ( Purple wire ) to Digital pin 7 of the Arduino board( Picture 2 ).

Connect the Clock wire ( Gray wire ) to Digital pin 6 of the Arduino board( Picture 2 ).

Connect the other end of the Ground wire ( Black wire ) to Ground pin of the Arduino board( Picture 2 ).

Connect the other end of the Power wire ( Red wire ) to the 5V power pin of the Arduino board( Picture 2 ).

Connect Ground ( Black wire ), Direction ( Purtle wire ), and Clock ( Gray wire ) to the Rotary Encoder Module ( Picture 1 ).

Connect the Female end of a Female-Male Power ( Red wire ) to the power pin of the Rotary Encoder Module ( Picture 1 ).

Step 3: Connect the Rotary Encoder to the Arduino

Picture 5 shows where are the Ground, 5V Power, and Digital 2 to Digital 5 pins of the Arduino Nano.

Connect the IN4 wire ( Orange wire ) to the Digital pin 5 of the Arduino board ( Picture 4 ).

Connect the IN3 wire ( Yellow wire ) to the Digital pin 4 of the Arduino board ( Picture 4 ).

Connect the IN2 wire ( Green wire ) to the Digital pin 3 of the Arduino board ( Picture 4 ).

Connect the IN1 wire ( Blue wire ) to the Digital pin 2 of the Arduino board ( Picture 4 ).

Connect the other end of the Ground wire( Black wire ) to Ground pin of the Arduino board ( Picture 3 ).

Connect the Female End of another Female-Male Power wire ( Red wire ) to the 5V power pin of the Arduino board ( Picture 3 ).

Connect the Female end of a Female-Male Power ( Red wire ), to the Power(+) pin of the Stepper Driver Module ( Picture 2 ).

Connect Female-Female Ground ( Black wire ), to the Ground(-) pin the Stepper Driver Module ( Picture 2 ).

Connect one end of Female-Female jumper wires ( Blue, Green, Yellow and Orange wires ) to the IN1 to IN4 pins of the Stepper Driver ( Picture 1 ).

If not already connected, plug the Stepper Motor connector into the Driver Board.

The rotary encoder I am using is this one. think its been turned one click forward and then one backwards).

This happens with all methods I've tried where one way will turn fine, the other it will bounce (e.g. (New position is number of steps motor should be turning) Moving 2 clicks clockwise.Īdding the stepper line, moving 2 clicks clockwise gives me.įinally if I turn the encoder 1/2 a click at a time slowly it reacts as expected. If I remove the t(newpos-curpos) line it shows as it should in console examples. I have tried multiple different examples and best I get is it works in one direction, this method uses the Stepper class from libary and does not work in either direction.

but turning clockwise it will show counting up, anti-clockwise counting down.Īs soon as I add the code to actually move the stepper motor it goes to hell.

If I use code for rotary encoder on it's own just outputting to serial console it appears to work fine albeit a click jumps up 4 positions. However I am having a frustrating problem when combining both.

I intended to do this with an arduino nano connected to a stepper motor and using a rotary encoder to simply translate a turn on encoder to a turn on the stepper motor (with adjustments for speed to follow). I am designing a remote electronic focus control for a telescope (to avoid having to touch telescope during focusing causing wobble).
