Introduction: DIY Arduino Based Bobbin Winding Machine
Hello makers in this post about DIY automatic Arduino based bobbin winding machine.
Bobbins are the small metal spools used in sewing machine, bobbins are filled with thread to stich cloths. This bobbins are frequently getting empty and you need to rewind it with thread again and again. So I made this machine it can automatically wind thread to maximum 12 bobbins in single run. there are already many bobbin winding machines are available in market. But there prices are more than 500$ but my this DIY arduino based bobbin winding machine can build under 100$.
JLCPB is best PCB manufacturer they have very resonable PCB pricing and fast PCB production
You can surely consider JLPCB for your any PCB needs
$2/5pcs 2Layer & $5/5pcs 4Layer PCBs: https://jlcpcb.com
Step 2: Material Required Below is the list of Item which I used to build this machine, material is totally depends how you design your machine.

Step 4: Circuit Drawing
Below is the circuit drawing of My multipurpose PCB which I have ordered from JLCPB.COM
Step 5: Arduino Code
