Background: Raspberry Pi Pico W and AP Mode

The Raspberry Pi Pico W is a powerful microcontroller board that combines the flexibility of the Raspberry Pi ecosystem with the compactness of a microcontroller. It features a dual-core ARM Cortex-M0+ processor, 264KB of SRAM, and built-in Wi-Fi and Bluetooth connectivity.

One of the standout features of the Pico W is its ability to function as an access point (AP). In AP mode, the Pico W acts as a wireless router, allowing other devices to connect to it and access its services. This opens up a world of possibilities for creating your own wireless networks and controlling devices remotely.

Now that you understand the background of the Raspberry Pi Pico W and AP mode, let’s dive into the step-by-step process of setting up the Pico W as an access point.

Step 1: Setting up the Raspberry Pi Pico W in AP Mode

To set up the Raspberry Pi Pico W in AP mode, you will need the following:

• Raspberry Pi Pico W board
• Micro USB cable
• Computer with Thonny IDE installed

Here are the steps to set up the Pico W in AP mode:

1. Connect the Pico W to your computer using the micro USB cable.
2. Open the Thonny IDE on your computer.
3. Click on “File” and then “Open” to open a new Python file.
4. Copy and paste the following code into the Python file:

import network
import time

def activate_ap_mode():
    ap = network.WLAN(network.AP_IF)
    ap.active(True)
    ap.config(essid="MyNetwork", password="mypassword")

def main():
    activate_ap_mode()
    while True:
        time.sleep(1)

if __name__ == "__main__":
    main()

5. Replace "MyNetwork" with the desired name for your network and "mypassword" with a secure password.
6. Save the Python file with a .py extension.
7. Click on the green “Play” button in Thonny IDE to run the code.

Congratulations! You have successfully set up the Raspberry Pi Pico W in AP mode. The Pico W will now act as an access point, allowing other devices to connect to it.

Step 2: Creating a Web Server

Now that the Raspberry Pi Pico W is set up in AP mode, we can proceed to create a web server. The web server will allow you to host your own network and control devices remotely.

Here are the steps to create a web server using the Pico W:

1. Open a new Python file in Thonny IDE.
2. Copy and paste the following code into the Python file:

import network
import time
from machine import Pin
from http.server import BaseHTTPRequestHandler, HTTPServer

def activate_ap_mode():
    ap = network.WLAN(network.AP_IF)
    ap.active(True)
    ap.config(essid="MyNetwork", password="mypassword")

def handle_request(request):
    request.send_response(200)
    request.send_header("Content-type", "text/html")
    request.end_headers()
    request.wfile.write(b"<h1>Welcome to My Web Server!</h1>")

def main():
    activate_ap_mode()
    server = HTTPServer(("0.0.0.0", 80), BaseHTTPRequestHandler)
    server.handle_request()

if __name__ == "__main__":
    main()

3. Replace "MyNetwork" with the name of your network and "mypassword" with the password you set earlier.
4. Save the Python file with a .py extension.
5. Click on the green “Play” button in Thonny IDE to run the code.

Your web server is now up and running! You can access it by connecting to the network created by the Raspberry Pi Pico W.

Step 3: Connecting to the Network and Accessing the Web Server

To connect to the network created by the Raspberry Pi Pico W and access the web server, follow these steps:

1. On your device (e.g., smartphone, laptop), go to the Wi-Fi settings.
2. Look for the network with the name you specified earlier (e.g., “MyNetwork”).
3. Connect to the network using the password you set.
4. Open a web browser and enter the IP address of the Raspberry Pi Pico W (e.g., 192.168.4.1).
5. You should see the web server’s welcome message displayed in the browser.

Congratulations! You have successfully connected to the network created by the Raspberry Pi Pico W and accessed the web server. You can now control devices, share files, or perform any other tasks you desire.
