Make a Python Powered ChatBot #Raspberry Pi

Hello Guys,In this instructables i am going

show you how to make simple Python based chatbot. it's not powerful as Amazon alexa.

Must watch the video first (click here)

Step 1: Requirements

Hardware :

#Raspberry pi 3

(Note:-You can use Can raspberry pi version make sure you have connected wiffi Dongle to it)

Software:

#Python2

(No need to install python it is already install on raspberry pi)

Connect LED to GPIO 11.

Step 2: Working

NOW let me explain how this chatboat works here raspberry pi works as server& our app acts as client. Python server on Raspberry pi handles all the requests from the client. make sure RPi & android phone should be connected to same wiffi network.

You can also access your server outside Your Home wiffi network by Port forwarding.

Step 3: Android App

I have created this android app using MIT app inventor 2.

This app is basically a TCP client which make communication with server.

You can Download this app from below link(click here).

I have provided .aia file of MIT app inventor project you can import it & edit it according your needs.

Step 4: Python Server

open Python 2.7,Copy this code & paste it.

then Run this code.

You can modify it according to your needs.

import socket
import sys
import RPi.GPIO as GPIO
from thread import *

import datetime
import random
import requests
import os

GPIO.setwarnings(False)
GPIO.setmode(GPIO.BOARD)
GPIO.setup(11,GPIO.OUT)

host = ''
port = 8220
address = (host, port)

server_socket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
server_socket.bind(address)
server_socket.listen(5)
#Variable for the number of connections
numbOfConn = 0

#Name of list used for connections
addressList = []
clients = set()
