Conquering electronics with a Raspberry Pi!
In the Next Adventure
The inal adventure in this topic is a humongous Raspberry Pi project. It draws
on all the computational skills you have learned on your Pi journey so far, to
enable you to make a Pi Jukebox with LCD display, Play, Stop and Skip
buttons—and a box! It will also involve acquiring extra parts for your Raspberry
Pi, like an LCD screen. The project may seem intimidating at irst, but as with all
challenging endeavors, you will feel triumphant when it is completed.
