# Raspberry Pi Input 

## About the GPIO of the raspi
The Raspberry Pi provides Input/Outport ports 
intended to control or monitor other devices and 
subsystem modules. These `GPIO` (general purpose I/O) 
signals on the 2x13 header pins on the RPi motherboad 
include SPI, I2C, serial UART, 3V3 and 5V power.

## Interaction
You can control these GPIO pins on the raspi. Just install `brainbox` 
on your RaspberryPi.

## Install

```
sudo npm install -g brainbox
````

This takes a while on a raspbery B+ 2 but should success.

## Start the server on the raspi
after this you can start the BrainBox server on the raspberry
with

```
brainbox 
```

## Connect with the browser

After this the BrainBox echos the url on the console 
how to connect with your browser to your Hardware.

Now you can drive the GPIO pins on raspi with the `brainbox`
