Arduino Uno.
I used an Arduino Uno board for this project, if you have never used an Arduino board before, you can get started right now, it's commonly known as the easiest product to program and to apply hardware connections so that you can carry out your electronic project.
One Shield.
I used 1Sheeld board ,the 1Sheeld mobile application and the Text To Speech functions. If you have never used a 1Sheeld before you can also get started right away. It's a board that gives your project the ability to communicate with your smart phone. For example if your project needs a Camera, a GPS module, a GSM module or whatsoever (It contains more than 40 shields), then you can use the accurate shields on your phone using the 1Sheeld free mobile application, instead of external components.
Also download the mobile application here.
TWO ultrasonic sensors.
In this prototype we will just work on one shoe, so for this half we will need an ultrasonic sensor that points ahead of the shoe, and another one points 45 degrees to the right.
ultrasonic sensors detect the distance in front of them, so we will use them to detect how far the obstacles are.
A tiny breadboard.
To provide 5 volt source for the sensors.
Arduino Battery Jack.
Just to power the arduino while walking.
Jumper wires.
We will use male-female type.
A 9volt Battery.
A shoe.
Pick a shoe that you think will be easy to attach the components on.
Nylon cable ties.
To attach all the components on the shoe you pick. Of course you can attach them any other way but this is how I made it.
