## **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.
