DIY Arduino based Toroid coil winding Machine | Arduino project

$2/5pcs 2Layer & $5/5pcs 4Layer PCBs: Hello friends In this video I have made a toroid coil winding machine using arduino as controller, This machine is automatically winding the turns and also rotate toroid core automatically. For user input and interaction I have used a rotary encoder and 16x2 LCD display. User can enter data like diameter of toroid core, number of turns and how much area of toroid core need to wind. I have program it in a way so it can be used for variety tor ID/OD t
