Wiznet's W5100s-EVB-PICO with Peizo Buzzer playing music

With the use of Wiznet's W5100S-EVB-PICO and Peizo Buzzer will paying the musical notes of selected song via PWM

This project is based on Wiznet's W5100S-EVB_PICO with circuitpython,Its just a small project of showcasing interfacing Buzzer and playing musical notes by contolling PWM pins in W5100s-EVB-PICO board via Web server.

Hardware Specification ​

Pin-out ​

W5100S-EVB-Pico pinout is directly connected to the GPIO of RP2040 as shown in the picture above. It has the same pinout as the Raspberry Pi Pico board. However, GPIO16, GPIO17, GPIO18, GPIO19, GPIO20, GPIO21 are connected to W5100S inside the board. These pins enable SPI communication with W5100S to use Ethernet function. If you are using the Ethernet function, these pins cannot be used for any other purpose.
