# Navigation using Directions

Build a Device that can be used to navigate using the compass feature and the arrows (either the  pre-build microbit  arrows or design your own)

### Basic Guide Lines

* [ ] Pick one of the 4 main directions (N  S  E  W)
* [ ] Design a Program that will  detect if the micro:bit is NOT  traveling in your chose direction
  * [ ] What will you show if you are ON course 

    * [ ] If your current compass reading = the direction you picked

  * [ ] What will happen if you are OFF course?
    * [ ] Alert Captain?
    * [ ] Notify direction they are currently traveling
    * [ ] Use arrows to show which way to turn the boat to head in the correct direction
    * [ ] Notify Captain when back on  course

#### Extensions: pick some of these or make your own

Add the ability to for the user to select a navigational setting before the trip begins

Add the ability for the captain to "set" a direction setting by moving the microbit before the trip begins

Add the 8 point direction functions

Modify the ranges so that you are not going "relatively north" but are following a specific degree marker
