Hello, this article is about DIY's automatic winding machine based on Arduino.
Be
The spool is a small metal wire used in the sewing machine, and the needle punches are filled on the spool.
The spool is often emptying, and you need to use a thread again and again.
Therefore, I can automatically pass the wire to up to 12 bobs in one run. There are already many bobbin winding machines available in the market.
But here is more than $ 500, but the price of this Arduino-based DIY bobbin winder can be less than $ 100.
