Hello friends in this video I have made a thread coil winding machine, using arduino and 3D printed parts, for GUI I have used 0.96 OLED display and for user input I have used a rotary encoder knob. a Photoelectric Speed Sensor is used the measure the length of thread.
Machine have two mode of operation 1st is manual mode in which thread start to wind on coil until stop is not pressed in in 2nd mode Auto mode machine will wind the thread as per the user predefined length.
