I have made a Automatic wire cutting machine using Arduino nano controller board.
Basically there are 3 process level of this machine like
1) first process is Input
Input like wire length and wire quantity provided by pressing push button also the real time data can read on 16 X 2 LCD
all the inputs were processed by arduino nano and give command to stepper motor to feed required length of wire and instruct to servo to make cut of required quantity.
Stepper motor, servo motor & cutter are the final output component”
