Digital Write Pin

Write the value 0 or 1 to the specified (digital) pin. Some pins are also used by the display, read the pin documentation carefully.

pins.digitalWritePin(DigitalPin.P1, 1)

Parameters

• name - the pin name (P0, P1, P2, ...)
• value - 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:

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)
    }
})
