 # Lessons Learned
 
+The code in this lesson is unremarkable; the lessons here were primarily in correcting some fundamental misunderstandings in my basic electronics knowledge.
+
 - Resistors in a circuit don't work the way I thought they did
 - How a voltage divider actually works and why we might use one
 - How a photoresistor actually works under the hood
