1Step - 1 : Collect all necessary component
You can find component list in component list section
-
2Step - 2 : Connection all componet
Connect all component according to this diagram. You will need a good quality soldering iron to connect all together.
-
3Step - 3 : Connect Programmer
To upload code in Arduino Pro Mini you will need a FTDI adapter or another arduino as programmer. (This image has been taken from Arduino Website)
-
4Step - 4 : Upload Code
Open arduino ide and select board as arduino pro mini. also select correct com port and upload following code.

5Step - 4 : Insert everything in glove
Carefully insert in glove. Different glove need different technique to insert. If you use a bicycle glove you can insert arduino and all other component user its plastic protection. See this picture for an idea.
Make sure sensor is in correct position. Make a square space for on/off switch.

6Step - 5: Final Step
Now check whether everything is working. Finally try to give it to visually impaired people and take feedback from them to further improvement.
