Smartphone Controlled Winding Machine

Sometime when I need some wire so I took a full thread spool but I am done with my work it is difficult to rewind all that again. So today I though to make a winding machine. First I build a thread winding Machine. Then I programmed it to be controlled via Bluetooth. So I just used an old app for controlling because I didn’t have time to program.

Required Components:

Screw Driver
Nose Player
Solution
Ball Point
Dc Motor
Glue Stick
Copper Wire
Rubber Bands
Arduino Board
Motor Driver
Bread Board
Old Cds
Taps
Bluetooth Module
Jumper Wire
2x Paper Sheet
Blade
3x Wooden Rulers
Andriod App (Link Is Given At End)

Procedure:

First mark 2 of the wooden rulers at 6.5 inches and 11.5 inches. And the the reaming at 7 cm and 14 cm.
Then cut the ruler according to marks. So it become 2X 6.5 inches 2X 4 inches And 2X 7 cm.
Then join 6.5 and 4 inches with help of glue stick and make a rectangle from it.
After that take the 7c and from one side on 6.5 inches at 1.5 inches glue it mean here will be the stand. (First make for one side)
Then take a gluestick and roll it in both sheet of paper. After that use some tape on it so it will become completely round.
Then take the copper wire and make a ring from it according to spindle. And Glue it on the top of 7 cm.
Then Insert the spindle along with CDs.
After that glue the 7 cm remaining on another side.
Attach the Dc Motor at the other side on 6.5 Inches. Then Make circuit according to given pic below.
Upload the code from below to your Board. ( Don’t Forget to remove the Tx & Rx Pins while uploading)
