It holds the main.py file which manages the AI classification logic of the device. It also holds the requirements.txt file, start.sh and test_display.py.
### Physical Folder ###
The Physical folder is the base for all sensing and actuating functions. It holds the two folders - Arduino and Node-Red, as well as the file lcd_display.py, which is used by the Node-Red for LCD outputs.
The Arduino folder holds the two Arduino sketches, one for each Arduino (Arduino 0 and Arduino 1). These Arduino numbers are to be assigned based on the ACM port each Arduino is connected to via USB (ACM0 and ACM1). The Node-Red folder holds the Node-Red flow .json which needs to be manually imported to Node-Red.

#### Prerequisites ####
### Prerequisites ###
**Node-Red**
- Install Node-Red with `bash <(curl -sL https://raw.githubusercontent.com/node-red/linux-installers/master/deb/update-nodejs-and-nodered)`.
- On completion, run it with `node-red`. Open the given link for the browser interface.
- Navigate to Settings>Manage Palette.
- Navigate to *Settings>Manage Palette*.
- Ensure the following packages appear:
-`node-red`
-`node-red-node-serialport`
- If not, search for and install them.
**Arduino IDE**
- Install the IDE with `sudo apt-get install arduino`.
- With the IDE, go to *Tools>Manage Libraries...*.
- Install the `Servo` library.

#### Swapped Arduino Functions ####
It's important that the two Arduinos are correctly configured with the right components, sketch, and serial port. If, on monitoring in Node-Red, the Arduinos have swapped functions, it's most likely the serial ports are incorrect. It should be Arduino 0 = ACM0 and Arduino 1 = ACM1. The easiest way to correct this is by unplugging both Arduinos and replugging them, with Arduino 0 being plugged in first.
#### Stranded in Middle of Node-Red Flow ####
If a component is misconfigured and interferes at a point in time after passing the Lock node but not the Unlock node, the system will never reset and won't take accept new inputs. If this happens, stop Node-Red with ctrl+c and re-enter `~/cm2305/pi/start.sh`.
