Raspberry Pi project: Simple Chatbot
This project aims to create a simple chatbot using a Raspberry Pi 5. A chatbot is an automated program that is able to mimic human interactions and conversations. With this step-by-step plan you can create a simple basic chatbot and have it run on you Raspberry Pi. You'll learn how to use Python, install and customize some necessary libraries, and ultimately have an interactive chatbot capable of responding to your input. This project can also be done on the Raspberry Pi 4B.

Step 2: Preparation
- close the Raspberry Pi 5 and start up the Pi.
- Open the Thonny IDE
- Open the terminal
Step 3: Install Python libraries
Before you can run the code, make sure you have the necessary Python libraries installed on you Raspberry Pi 5. You can install these libraries using pip, the Python package manager. Open a terminal on you Raspberry Pi 5 and run the following commands to install python and pip:
sudo apt-get updatesudo apt-get upgrade
sudo apt install python3
sudo apt install python3-pip
Now install the python libraries:
pip install -U chatterbot==1.0.4
Finally, restart the Raspberry Pi to complete the installation:
sudo reboot
Step 4: Code
Copy and paste the code into Thonny.
from chatterbot import ChatBot
# Create a new instance of a ChatBot
bot = ChatBot('Terminal',
storage_adapter='chatterbot.storage.SQLStorageAdapter',
logic_adapters=[
'chatterbot.logic.MathematicalEvaluation',
'chatterbot.logic.TimeLogicAdapter',
'chatterbot.logic.BestMatch'
],
database_uri='sqlite:///database.db'
)
print('Type something to start…')
# The next loop runs each time the user provides input
while True:
Try:
user_input = input()bot_response = bot.get_response(user_input)
print(bot_response)
# Press ctrl-c or ctrl-d on the keyboard to quit
except(KeyboardInterrupt, EOFError, SystemExit):
break
Step 5: Run code
a. Save the Python script with an appropriate name, e.g chatbot.py.
b. Navigate to the folder where you saved the Python script.
c. Run the script with the following command:
d. By using the chatbot more often and adding sentences to its training set, the chatbot will answer your questions better.
python chatbot.py
Step 6: Extend chatbot (optional)
- Add more example sentences and responses to make the chatbot smarter.
- Adjust the parameters in the
ChatBotvariable to get more specific results. - Expansion options: ChatterBot Corpus — ChatterBot 1.0.8 documentation
python chatbot.py
