Take a moment to review the completed code provided above. This is the code you will be working with throughout the lesson.

Start by importing the necessary libraries for this project. Add the following lines of code at the beginning of your script in Thonny editor:

import network
import socket
from time import sleep
from picozero import pico_temp_sensor, pico_led
import machine

Replace 'WIFI_SSID' and 'WIFI_PASSWORD' with your WiFi network's SSID and password. Then, add the following code to create a function called 'connect' that connects your Raspberry Pi Pico to the WiFi network:

ssid = 'WIFI_SSID'
password = 'WIFI_PASSWORD'

def connect():
    #Connect to WLAN
    wlan = network.WLAN(network.STA_IF)
    wlan.active(True)
    wlan.connect(ssid, password)
    while wlan.isconnected() == False:
        print('Waiting for connection...')
        sleep(1)
    ip = wlan.ifconfig()[0]
    print(f'Connected on {ip}')
    return ip

Add the following code to create a function called 'open_socket' that opens a socket for your Raspberry Pi Pico:

def open_socket(ip):
    # Open a socket
    address = (ip, 80)
    connection = socket.socket()
    connection.bind(address)
    connection.listen(1)
    print(connection)
    return connection
