+# Day four:
+
+Play a Christmas carol (or a song you like) using the Barduino.  
+
+Time to make some music! Use the buzzer (or any other thing!) to make some music, the idea is to play a Christmas carol. As we come from many different places, try to play one from your hometown, to have a nice collection of tunes :partying_face:
