+  Esplora Pong
+ 
+ This  sketch connects serially to a Processing sketch to control a Pong game.
+ It sends the position of the slider and the states of three pushbuttons to the 
+ Processing sketch serially, separated by commas. The Processing sketch uses that 
+ data to control the graphics in the sketch.
+ 
+ The slider sets a paddle's height
+ Switch 1 is resets the game
+ Switch 2 resets the ball to the center
+ Switch 3 reverses the players
+ 
+ You can play this game with one or two Esploras.
