Connect Opto sensor to Uno

[ec2021]

As the TB6600 does not provide stabilized 5VDC you have to choose one of the solutions. Maybe that you take advantage of the knowledge in a future project.

For this project you can use the 5V pin to set those signals of the driver board to HIGH which do not have to be controlled by the software. This saves you probably valuable digital pins for other purposes.

As digital input electronics do not consume any significant current, you can easily connect several inputs to the 5V pin.

Hello all,

I did some more learning on TB6600 and found another video to wire it up a bit differently using ENA+/DIR+/PUL+ instead of DIR-/PUL-. It is the opposite way to wire it using the GND pin, not using the 5v pin at all.

Thought I would post this. Its all good, both ways would work and the code is only slightly different but this makes more sense to me. Here is a pic and a link to video.
