-micros()
-========
-
-Description
------------
-
-Returns the number of microseconds since the Arduino board began
-running the current program. This number will overflow (go back to
-zero), after approximately 70 minutes. On 16 MHz Arduino boards
-(e.g. Duemilanove and Nano), this function has a resolution of four
-microseconds (i.e. the value returned is always a multiple of
-four). On 8 MHz Arduino boards (e.g. the LilyPad), this function
-has a resolution of eight microseconds.
-
-
-
-*Note*: there are 1,000 microseconds in a millisecond and 1,000,000
-microseconds in a second.
-
-
-
-Parameters
-----------
-
-None
-
-
-
-Returns
--------
-
-Number of microseconds since the program started (*unsigned long*)
-
-
-
-Example
--------
-
-::
-
- unsigned long time;
-
- void setup(){
- Serial.begin(9600);
- }
- void loop(){
- Serial.print("Time: ");
- time = micros();
- //prints time since program started
- Serial.println(time);
- // wait a second so as not to send massive amounts of data
- delay(1000);
- }
