Time

1. delay()

1.1. Description

Pauses the program for the amount of time (in milliseconds) specified as parameter. (There are 1000 milliseconds in a second.)

1.2. Syntax

delay(ms)

1.3. Parameters

ms: the number of milliseconds to pause (unsigned long)

1.4. Returns

Nothing

2. delayMicroseconds()

2.1. Description

Pauses the program for the amount of time (in microseconds) specified as parameter. There are a thousand microseconds in a millisecond, and a million microseconds in a second.

2.2. Syntax

delayMicroseconds(us)

2.3. Parameters

us: the number of microseconds to pause (unsigned int)

2.4. Returns

Nothing

3. micros()

3.1. Description

Returns the number of microseconds since the Arduino board began running the current program.

3.2. Syntax

time = micros()

3.3. Parameters

Nothing

3.4. Returns

Returns the number of microseconds since the Maixduino board began running the current program.(unsigned long)

4. millis()

4.1. Description

Returns the number of milliseconds passed since the Maixduino board began running the current program. This number will overflow (go back to zero), after approximately 50 days.

4.2. Syntax

time = millis()

4.3. Parameters

None

4.4. Returns

Number of milliseconds passed since the program started (unsigned long)
