How To Make Raspberry Pi Pico W Web Server – MicroPython

Introduction

In this article, we’ll show you how to make a Raspberry Pi Pico W web server using the MicroPython WebREPL client. This is a great way to get started with the coding on the Raspberry Pi Pico, and you can use this webserver to control things like GPIO output and read sensor data.

This guide will show you how to set up the Pico W and get it up and running. We’ll use Pionboardboard WiFi and web server abilities to control an LED. The Pico W is a great board for any Raspberry Pi project that requires wifi.

What is a Raspberry Pi Pico W?

Raspberry Pi Pico W adds on-board single-band 2.4GHz wireless interfaces (802.11n) using the Infineon CYW4343 while retaining the Pico form factor. The on-board 2.4GHz wireless interface has the following features:

The Pico is the first Raspberry Pi board to be built around the company’s new RP2040 microcontroller chip. The RP2040 chip features two CPU cores, each of which can run at up to 133 MHz, and comes with 264KB of on-chip RAM. The Pico also has a variety of I/O peripherals, including GPIO, I2C, SPI, UART, and PWM, as well as an on-chip USB controller.

Web Server – Client Process

Raspberry PI Pico W Web Server: using MicroPython

Web server – The client process involves communication between a web server and a web browser. The web server is responsible for handling the requests from the web browser and sending the appropriate response. The web browser is responsible for rendering the web page and displaying it to the user.

The communication between the web server and the web browser is done using the HTTP protocol. The web browser sends an HTTP request to the web server when it wants to retrieve a web page. The web server then processes the request and sends an HTTP response back to the web browser.

The web server and the web browser can be located on different computers in different parts of the world. The only requirement is that they are connected to the Internet.

HTML for Raspberry Pi Pico W Web Server

The HTML for Raspberry Pi Pico W Web Server is a great way to easily create a web server on your Raspberry Pi Pico W device. This is a great way to create a simple web page to display data from your Raspberry Pi Pico W device, or to control your device remotely. The HTML for Raspberry Pi Pico W Web Server is very easy to use, and it is a great way to get started with web development on the Raspberry Pi Pico W.

The Raspberry Pi Pico W is a web server that has WiFi capabilities. It is a low-power device that is also very portable, making it ideal for use in a variety of different settings.

The Raspberry Pi Pico Wseveraler of GPIO pins that can be used to control various devices and peripherals, and it also has a built-in ADC that can be used to take measurements from sensors.

Setup to blink LED via WiFi on Raspberry Pi Pico W

we will take a look at how to set up the Pico Wifi and how to use it to blink an LED.

Set up MicroPython on Raspberry Pi Pico W

  • First, you require to set up MicroPython. Download the UF2 file here that’s especially meant for the Pico W.
  • Hold down the BOOTSEL button and connect your Pico W via USB to your laptop.
  • Once it’s mounted, copy the UF2 file that you just downloaded onto the Pico.

You can check here How to Set up MicroPython on Raspberry Pi Pico  Use Thonny IDE to program Raspberry Pi Pico W Thonny makes it easy to program the Raspberry Pi Pico W and it comes pre-installed on the Raspberry Pi OS. You can also download it for Windows here. Make sure your interpreter is set to MicroPython (Raspberry Pi Pico).

Raspberry Pi Pico W Test Script

Run a network scan to confirm Pico W wireless is working

Use this code to print out all available wireless networks in your location.

When run on a Raspberry Pi Pico W it will allow the network interface, scan for wireless networks & print them on the shell.Run a network scan to confirm Pico W wireless is working

Program the Raspberry Pi Pico W Web Server

Create a code called secrets.py and use the following content, replacing the value for SSID and Password with your network.

secrets.py

Create the HTML Page

The following line will be the HTML file that’s done when you load Pico W’s IP address. Save it asindex.html It’s an easy page with two buttons that allow you to turn the Pico W’s LED on and off.

index.html

Then, make main.py which will host your primary code.
