# Digital Write Pin
|
|
|
|
Write the value ``0`` or ``1`` to the specified (digital) [pin](/device/pins). **Some pins are also used by the display, read the [pin documentation ](/device/pins) carefully.**
|
|
|
|
```sig
|
|
pins.digitalWritePin(DigitalPin.P1, 1)
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* name - the pin name (``P0``, ``P1``, ``P2``, ...)
|
|
* value - [Number](/reference/types/number); 0 or 1
|
|
|
|
### Example: football score keeper
|
|
|
|
The following example reads `P0` to determine when a goal is scored. When `P0 = 1`, the code uses `digital write pin` to play a buzzer sound:
|
|
|
|
```blocks
|
|
let score = 0
|
|
basic.showNumber(score)
|
|
basic.forever(() => {
|
|
if (pins.digitalReadPin(DigitalPin.P0) == 1) {
|
|
score++;
|
|
pins.digitalWritePin(DigitalPin.P2, 1)
|
|
basic.showNumber(score)
|
|
basic.pause(1000)
|
|
pins.digitalWritePin(DigitalPin.P2, 0)
|
|
}
|
|
})
|
|
```
|
|
|
|
