I am very new to this, just got my first Arduino last week, so still very confused. I would like to ask a few questions if I may, as a turntable for an OO gauge layout is my goal.
I see that you are using a direct drive. As the motors seem to have 200 steps, this gives a resolution of 1.8 Degrees. At the outer edge of a 325mm dia TT this is a step of about 5mm, dose this not make it a bit jerky??
I was planning on a 5:1 belt drive.??, would this not be an improvement??.
My ideal way of operating would be to have a button to press for each position. A maximum of 8 positions. The TT moving from wherever it is, to the required position.
Is this possible/practical.
I feel that the chances of me being able to write the required program (sketch?) for this is about 1000:1, so is here anyone out there who has done this and could supply me a copy of said program.
Please be gentle with me...
Many thanks for any help that you may be able to give.
