This project utilized two Discord bots to watch a laser trip wire where a master bot, named Wire_Bot, a.k.a Hal, who responded to certain commands in general chat. The images below demonstrate what prompts Hal would respond to, and the last two pictures show a simple setup for the trip wire.

Here's a list of components used in the project:

Next, lets take a look at the two circuits.

Create two Discord bots and provide them with read and send permissions for your chosen server. The bot Wire_Bot, the master bot, responds to chat commands and since we don't want this bot to be blocked when watching the trip wire, another bot, Watch_Bot, is assigned this task (which was only used to log on to noftify general chat that the wire has been tripped, and then immediately logs off).

After setting up both the laser and light sensor circuits make sure they are working by using the 'test_devices.py'.

In the root directory of the project create a file '.env'. This will contain a safe place for storing the tokens for the bots. Add the tokens and the following variables to '.env':

DISCORD_TOKEN=[Add token for Wire_Bot]
DISCORD_TOKEN2=[Add token for Watch_Bot]

Next, in files 'main.py' and 'watch_bot.py', there is a global variable called 'GENERAL_CHANNEL_ID', that must be defined using your server's general chat ID.

Finally, install necessary packages used in this project:

pip install -r ./docs/requirements.txt

Then, start running the application:

python main.py

Expect the bot, Hal, to greet you in general chat, as shown in the bellow image:

When done with application, close main program with 'Ctrl + c'
