[Time]
説明
Returns the number of microseconds since the 86Duino board began running the current program. This number will overflow (go back to zero), after approximately 70 minutes. This function has a resolution of one microsecond.
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 Code
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); }
