+ 
+ This example shows how to use the Bridge library to access the digital 
+ and analog pins on the board through REST calls. 
+ It demonstrates how you can create your own API when using REST style 
+ calls through the browser.
+ 
+ Example of possible commands are listed here:
+
+ "/arduino/digital/13"     -> digitalRead(13)
+ "/arduino/digital/13/1"   -> digitalWrite(13, HIGH)
+ "/arduino/analog/2/123"   -> analogWrite(2, 123)
+ "/arduino/analog/2"       -> analogRead(2)
+ "/arduino/mode/13/input"  -> pinMode(13, INPUT)
+ "/arduino/mode/13/output" -> pinMode(13, OUTPUT)
+
+ The circuit:
+ there is no need of a particular circuit, you can connect:
+ * some analog sensors to the analog inputs
+ * LEDs to digital or analog outputs
+ * digital sensors such as buttos to the digital inputs
