Hand-On Tutorial for Raspberry Pi DIY project

Use raspberrypi and AD converter to make a MP3 music player

In this project, we will use potentiometer to control the volume of  music player. As raspberry pi can not accept analog signal from potentiometer , we need to use ADC module to convert analog signal to digital signal before sending it to
