Transform Raspberry Pi into an Internet Radio

The Raspberry Pi can be transformed into an internet radio using Python and the GPIO Zero library. This project employs two potentiometers connected to an MCP3008 analogue-to-digital converter (ADC) chip to control station selection and volume. The ADC communicates with the Raspberry Pi via the SPI protocol, enabling precise readings from the potentiometers. One potentiometer adjusts the LED brightness, while the other controls the station and volume of the internet radio. The setup involves connecting the MCP3008 to the Raspberry Pi’s GPIO pins and wiring the potentiometers and an LED to the breadboard. Python code is used to read the potentiometer values and control the LED’s brightness and the radio’s functionality. The VLC media player is installed to stream internet radio stations, with the ability to switch between stations and adjust volume dynamically. This project demonstrates the versatility of Raspberry Pi in integrating hardware controls with software applications for practical uses like creating a personalized internet radio.
