Project Description: This project involves building a glove that allows you to take photos simply by making the symbolic picture sign, by connecting each thumb to the opposite hand's index finger. Also, with different modes, you can select picture mode, video modes, and even activate other cameras in the nearby area.

To run the whole system:

1. Run the java distributed server on "unix4.andrew.cmu.edu" with port 4863 i. ssh <andrew_id>@unix4.andrew.cmu.edu ii. cd <folder_containing_server>/ iii. javac Server.java iv. java Server

2. Boot up each Raspberry Pi and use as directed. i. Connect Raspberry Pi pins to the circuit as needed ii. Make sure WIFI dongle is connected iii. Make sure SD Card is inserted iv. Connect camera v. Connect to power

To configure Server:

1. Make sure configured to run on port 4863

To configure Raspberry Pi:

1. mkdir ~/snap

2. mkdir ~/snap/scripts

3. scp main.py pi@:~/snap/scripts

4. scp configs.py pi@:~/snap/scripts

5. vi ~/.profile add "sudo ~/snap/scripts/main.py" to the end of the file

6. Instal python lib "picamera" i. sudo apt-get install python-setuptools ii. sudo pip install picamera

Pin Configuration: Output: 3 - GREENLED 5 - REDLED

Input: 7 - TAKE_LIVESTREAM 11 - TAKE_PHOTO 13 - TAKE_VIDEO 15 - TAKE_DISTRIBUTED_PHOTO

Voltages: 1 - 3.3V 9 - GND

What does main.py do:

1. Creates "imgs" folder if needed
2. Sets up the pin inputs and outputs
3. Checks if WIFI has been connected
4. Connects to SERVER on unix4.andrew.cmu.edu
5. Sets up the triggers that enable the camera using functionality
