Скачать или смотреть How to control a dc motor with Arduino and encoder

In this video I show how I control a dc motor to accurately rotate a shaft. Of course the best option would be a stepper motor or servo but this gives some insight on some possible applications for this setup.

************ IMPORTANT NOTE :
Due to the nature of this encoder type, incremental type, your start position or "home position" will be set when you power on your Arduino.

If you want to increase or decrease the amount of rotations, go to into your code and change ALL the values that says (COUNTER 120) to a different number. In this setup 60 counts on the encoder equals to one full rotation at the output of the RIGHT HAND SHAFT , the LEFT HAND SHAFT spins 2 times faster but has half the torque.
So for example if you want 3 full rotations of the right hand shaft 60 x 3 = 180 , so change the 120 to 180 or if you want 2.5 rotations 60 x 2.5 = 150 etc.

All of the electronics needed to build this exact setup can be found on amazon.

3Pcs Mini Micro N20 Gear Motor DC 3V-6V Slow Speed Full Metal Gearbox DIY Robot Car
A generic 5 pin rotary encoder
a medium sized bread board 82 mm x 54 mm
I used the Arduino Nano for a compact setup but I'm sure other versions should work as well.

The 3D print files will be on my thingiverse page called "Imagined Prints". Ill name it " encoder gear box " to help with the search.

Any questions leave a comment on the video Ill try my best to help you out.
