## **GrovePi Open Wifi Finder**
GrovePi is an open source platform for connecting Grove Sensors to the Raspberry Pi. Create your Internet of Things devices and inventions, no soldering!
Scan for open wifi networks! This is a portable wifi hotspot finder. See our project [here](http://www.dexterindustries.com/GrovePi) for more information on turning this into a portable wifi hotspot finder.
### How Does it Work?
The GrovePi board slips over the Raspberry Pi. Connect the Grove Sensors to the GrovePi board.
####Software Setup Notes:
* This example uses [wifi library](https://wifi.readthedocs.org/en/latest/wifi_command.html). Install with pip install wifi
* Wifi dongle must be on wlan0 ; Check this with the command "ifconfig" on the command line.
####Hardware Setup Notes:
* Buzzer goes on port D2 of the GrovePi.
* LED Goes on port D3 of the GrovePi.
* The LCD goes on I2C-1. Check this with the command "sudo i2cdetect -y 1"
The GrovePi connects the Raspberry Pi and Grove sensors. You can learn [more about GrovePi here.](http://www.dexterindustries.com/GrovePi)
### Make This Start at Boot!
If you're going to take this outside, make sure you can start this at boot.
First, the files in this directory are copied into the home directory.
Make a script "start.sh" and put a command to start the wifi_finder.py script.
```
sudo nano start.sh
```
The contents of start.sh are going to be:
```
#!/bin/bash
sudo python /home/pi/wifi_finder.py
```
And then open up rc.local
```
sudo nano /etc/rc.local
```
and add the last few lines of this file should be:
```
sudo sh /home/pi/start.sh
exit 0
```
Then that's it! Reboot and test!

### Raspberry Pi Compatibility
The GrovePi is compatible with the Raspberry Pi models A, A+, B, B+, and 2.
### Programming the GrovePi
The GrovePi can be programmed in Python, C, C#, Go, and NodeJS on the Raspberry Pi. Simply start with one of our [example projects](http://www.dexterindustries.com/GrovePi/projects-for-the-raspberry-pi/) or [example code](https://github.com/DexterInd/GrovePi/tree/master/Software).
The GrovePi uses an Arduino to interface between the Raspberry Pi and the Grove Sensors, and comes programmed with a standard firmware. The firmware can be rewritten from the Raspberry Pi.
