# Pulse Duration
Gets the duration of the last pulse in microseconds.
This function should be called from an **on pulsed** handler.
```sig
pins.pulseDuration();
```
### Returns
The duration of the last pulse, measured in microseconds.
### Example
The following example waits for pin ``P0`` to be pulsed high, and then
displays the duration of the pulse in microseconds on the LED screen.
```blocks
pins.onPulsed(DigitalPin.P0, PulseValue.High, () => {
basic.showNumber(pins.pulseDuration());
});
```
