 ------------------------------------------------------------------------------------------------------
 
+Day 5 Complete!
+
+We've covered lots today fellow makers, pat yourselves on the back!
+
+As we cover more advanced topics such as functions, you may find that you need to refer back to these days to refresh your memory later on - and that's absolutely normal! Even the most seasoned professional programmers have to use search engines regularly (some even admit it!).
+
+So what did we cover on day #5? Today you have:
+
+    Built a circuit with a buzzer, your first audio component
+    Learnt how to use the buzzer with MicroPython and the Pico
+    Learnt about PWM frequencies and duty cycle with buzzers
+    Used analogue inputs to control audio volume using PWM
+    Created a festive jingle with MicroPython
+    Learnt how to use functions to make your code easier to manage and more efficient
