+	Dual counter example (Extended class example)
+
+  You could do many things with a dual counter. This example demoonstrates a scoreboard. Two players rol a dice every round, the player with the highest score wins the round. The number of rounds won are displayed on the scoreboard. Once one of the players reaches a maximum score the game is over. At the end of the game a player won message or draw will be displayed.
+
+	The circuit:
+  * connect TM1637 pin CLK to Arduino pin D4
+  * connect TM1637 pin DIO to Arduino pin D5
+  * connect TM1637 pin Vcc to Arduino pin 5V
+  * connect TM1637 pin GND to Arduino pin GND
