+ * Sample arduino sketch using contiki features.
+ * We turn the LED off 
+ * We allow read the moisture sensor
+ * Unfortunately sleeping for long times in loop() isn't currently
+ * possible, something turns off the CPU (including PWM outputs) if a
+ * Proto-Thread is taking too long. We need to find out how to sleep in
+ * a Contiki-compatible way.
+ * Note that for a normal arduino sketch you won't have to include any
+ * of the contiki-specific files here, the sketch should just work.
