Discord Bot

• A simple discord bot using the discord.py API
• I will also show you how to host the bot on a raspberry pi

Discord API Setup

• Go to Discord Developers site
• Create a new application and click on "Add bot"
• Go to "Bot" in settings
• Give him permissions to read & send messages
• Reveal your private token and save it
• Put it in a .env file in src/ folder

Python Setup

• Install Python 3.8

• Install the pip packages:

  pip install -r requirements.txt

• Run the script:

  python runDiscordBot.py

• Wait for the message : "Bot connected to the server!"

• Then you should see your bot online in your discord server

Host the bot on a Raspberry Pi

• Set up a raspberry pi with the raspbian OS

• Connect the raspberry pi to the internet with RJ45 or wifi (save password!)

• Edit the rc.local file to run the script so when the pi boots up it will automatically run the script:

  sudo nano /etc/rc.local

• Add a line above the exit 0 command that runs the script (with the full path):

  python3 /home/pi/src/runDiscordBot.py &

• Now you can reboot the raspberry pi:

  sudo reboot

• The bot will be online after reboot

Optional - Connect to the Raspberry Pi with SSH

• If you give the pi power and just connect it to the internet you don't have any control of it

• SSH will be a good solution

• Enable SSH in the raspberry pi configuraion under Interfacees tab

• Connect it from your computer:

  ssh pi@raspberrypi.local

• Enter your pi password

• Now you have a full control of your pi

Note : If you have multiple pies connected to your network, you will need to put the pi's ip insted of raspberrypi.local

Enjoy the bot!
