+#   Steps to test `set_default`:
+
+#   1. Run the program once to see what the current default value is
+#   2. Uncomment the call to `setWiperDefault` below and run it again.
+#   3. Once the program has run with the `set_default` call,
+#       comment out the line below again, then powercycle the DS3502 
+#       by removing then reattaching VCC
+#   4. Then run the program again with the line commented out to see the 
+#       new default wiper value
