# On Pulsed
|
|
|
|
Configure the specified pin for digital input, and then
|
|
execute the associated code block whenever the pin
|
|
pulses **High** or **Low** (as specified).
|
|
|
|
```sig
|
|
pins.onPulsed(DigitalPin.P0, PulseValue.High, () => { });
|
|
```
|
|
|
|
## Parameters
|
|
|
|
* ``name``: The @boardname@ hardware pin to configure (``P0`` through ``P20``)
|
|
* ``pulse``: Which state will cause the associated block to execute (**High** or **Low**)
|
|
|
|
## Example
|
|
|
|
The following example configures pin ``P2`` for digital input,
|
|
and then displays the string `LOW` whenever ``P2`` pulses low.
|
|
|
|
```blocks
|
|
pins.onPulsed(DigitalPin.P2, PulseValue.Low, () => {
|
|
basic.showString("LOW");
|
|
});
|
|
```
