 ------------------------------------------------------------------------------------------------------
 
+Day 7 Complete!
+
+That last activity included a lot of detail so we're going to leave it there for today and not overload your fresh coder brains!
+
+The PIR sensor can be so much fun to use and they come in all different shapes and sizes too, you'll be making your own home security system in no time.
+
+So what did we cover on day #7? Today you have:
+
+    Built a circuit with a PIR sensor
+    Learnt how to use a PIR sensor with MicroPython and the Pico
+    Created a mini alarm system!
+    Learnt about the range function
+    Revisited functions
