INTEGRATED GOOGLE MAPS

In this project we're going to implement a device that turns the indication from the Google Maps into a sensorial output to demostrate hwo we could use an integrated navigation system on our body.

We're going to implement this by connecting our Arduino board with our mobile phone device using a Bluetooth module. With our phone we can send the signal we want to our Arduino board that will activate with different patterns of the coin buzzer depending on the indication.

For now the indications will come from a Bluetooth app and not the actual Google Maps because our knowledge of programming doesn't go that far, however this project is all about showing that we could implement this is we had the tools.

There will be several indications for this, turn right or left (activating the right or left buzzer), go straight (activating both one time), incorrect way (activating both buzzers twice), end of the route (activating 3 times both buzzers) and sligh turn to lef ot right (activating with less power the left or right buzzer),

Here's the list of components you'll need to recreate the project.

-Arduino Lilypad.

-Bluetooth module HM-10

-Wires

-Coin buzzer (x2)

-Phone (preferebly Android)

-Welder

-Tin wire

Get a t-shirt with a pocket and place the buzzers one on each shoulder. The cables will go trhough the t-shirt and trough a hole that ens up on the fron pocket, There you will place the arduino board with everything connected. To be portable just connect the arduino with a battery and place it in the front pocket as well.

If you want you can also apply the same on some gloves, somewhere on the body in which is easy to distinguish the left/right indications.

If you have an Arduino Lilypad it becomes much more portable.
