/*
|
||
|
|
* 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.
