# Set Events
Configure the type of events emitted by a given pin.
```sig
pins.setEvents(DigitalPin.P0, PinEventType.Edge);
```
### Parameters
* ``name``: The @boardname@ hardware pin to configure (``P0`` through ``P20``)
* ``type``: The type of events this pin should emit
### Example
The following example configures pin ``P0`` and then
subscribes to the rise and fall events.
```blocks
control.onEvent(control.eventSourceId(EventBusSource.MICROBIT_ID_IO_P0), control.eventValueId(EventBusValue.MICROBIT_PIN_EVT_RISE), () => {
basic.showString("Rise")
})
control.onEvent(control.eventSourceId(EventBusSource.MICROBIT_ID_IO_P0), control.eventValueId(EventBusValue.MICROBIT_PIN_EVT_FALL), () => {
basic.showString("Fall")
})
pins.setEvents(DigitalPin.P0, PinEventType.Edge)
```
**This is an advanced API.** For more information, see the
[@boardname@ runtime messageBus documentation](https://lancaster-university.github.io/microbit-docs/ubit/messageBus/)
