In essence, the Pico W offers all the features of the original Pico with the added benefit of integrated WiFi.
How to Connect Raspberry Pi Pico to WiFi: A Step-by-Step Guide
Since the original Raspberry Pi Pico lacks built-in WiFi, you’ll need an external module to connect it to a wireless network. One popular option is the ESP8266 WiFi module.
Here’s a simplified guide on connecting your Pico to WiFi using the ESP8266:
-
Gather Your Materials: You’ll need a Raspberry Pi Pico, an ESP8266 WiFi module, jumper wires, a breadboard (optional), and a computer with a Micro USB cable.
-
Connect the ESP8266 to the Pico: Connect the ESP8266’s VCC and CH_PD pins to the Pico’s 3V3 pin. Connect the ESP8266’s GND to the Pico’s GND. Connect the ESP8266’s TX pin to the Pico’s RX pin, and the ESP8266’s RX pin to the Pico’s TX pin.
-
Install MicroPython on Your Pico: If you haven’t already, follow the instructions on the Raspberry Pi website to install MicroPython on your Pico.
-
Write the MicroPython Code: You’ll need to write a MicroPython script that configures the ESP8266 and connects it to your WiFi network. This script will involve sending AT commands to the ESP8266 to set the SSID and password of your network.
-
Upload the Code and Test: Upload the MicroPython code to your Pico. Once uploaded, open the serial monitor in your MicroPython IDE (like Thonny) to monitor the output and verify that the ESP8266 is successfully connecting to your WiFi network.
Remember: This is a simplified guide. You can find detailed tutorials and code examples on the Raspberry Pi website and various online resources.
