The Watchdog should automatically (re)start the Audio module on Raspberry Pi startup.

Responsibilities:

• Run Audio module on system startup;
• In case the module crashes, the watchdog should try restarting it.

This task is focused on building the base app for the Spike. This means only the app structure and visual elements are necessary. The structure (activities):

1. SyncActivity: This is the main activity (startup), and should enable Pireworks bluetooth devices Listing and Pairing. Therefore, must contain the following visual elements:
   • Device list: Name of the device and a 'pair' button.
   • Pairing dialog: A popup dialog that will be shown while the devices are pairing.
2. PireworksActivity: This activity should only be active if the phone is currently paired with a device. Must contain the following visual elements:
   • A TextView where the messages from the Pireworks backend will be displayed.
   • A button to send a test message to the backend.
   • A button to disconnect from the backend.

The Light Module spike should "listen" for the Audio Processing color inputs.
A few ways this could happen:

• Tunneling (linux |). Creates scripts so python audio.py | python light.py is possible.
• Sockets (tcp). Would require that both modules synchronize with it.
• Write/Listen to file. "audio.py" would write to a file, while "light.ph" would observe it, similar to tail -f color.log.

Define Python Abstract Base Classes for all the interfaces between components

The Watchdog should automatically (re)start the Pireworks Backend on Raspberry Pi startup.

Responsibilities:

• Run Backend on system startup;
• In case the Backend crashes, the watchdog should try restarting it.

An install script that allows for setting up the Light module on other devices.

• Install dependencies (programs, python dependencies)
• Creates/Copies files on the necessary paths
• Sets up Watchdog script.

Define and implement the audio to led interface. Values should contain RGB value and intensity for each.

The Light Module will interpret the colors and translate them to GPIO outputs signals. This will require prior setup of a simple RBG Led circuit with the Raspberry Pi.

1. LED circuit, with Raspberry Pi GPIOs.
2. Color interpretation
3. GPIO signal output

Some issues that will come next (worth exploring soon):

• How to make Multiple leds work? Could we use multiple colors?
• How to vary Intensity of the leds brightness?

This module will be hosted in the Pireworks Raspberry Pi, and will be the bluetooth interface of the system.

It should:

• publish the current device on bluetooth
• Accept pairing from the Pireworks Android App.
• echo the messages sent by the app.
• allow disconnection.

These are the responsibilities on the two activities of the Spike application:

1. SyncActivity.
   • Listing available bluetooth devices.
   • Pair with a Pireworks device.
2. PireworksActivity.
   • Read and display the messages sent by the backend.
   • Send a simple message (like "ping") to the backend.
   • Disconnect button, that will disconnect from the backend.

Use the main.py file to bootstrap the application. It is currently starting the Backend, but we'll also need to start the audio and light modules in the same file, so new configurations can be set.

• Install dependencies (programs, python dependencies)
• Creates/Copies files on the necessary paths
• Sets up Watchdog script.

The three peak frequencies are being detected, now find the magnitude of each. Determine the proper threshold (to be a configurable value in the future) to trigger an LED.
