+Analog digital workout
+----------------------
+
+This sketch showcases many different ways to write and read digital pins, 
+including generating clocks and creating binary counters.
+
+The code as it is will not work properly, as the direction of the pins is not 
+set. As an exercise, you will need to set the pin mode before writing or reading 
+the digital pins. 
+
+This is for advanced users only.
