Up till now almost all features have been completed except for pressure sensitivity.

I used arduino nano as my micro controller and two pressure sensors placed at the

front and at the back of the insole. A 9V battery was used to power the hardware.

Hurdles:

• Not enough space to embed the electronics in the insole
• Lack of good and cheap alternatives for supplying power
• Limited budget, so couldn’t purchase more sensors.
• Carving out the insole was difficult. The material is hard to work with
• Reliability issues with arduino nano (a known issue, that I should have known before purchasing it !!)

Accomplishments:

• Was able to get the device working
• Was able to fit all the hardware in the insole and hide it using a black fabric
• Even after modifications the design is relatively sleek and comfortable
