Pin Is Pressed

Gets the pin state (pressed or not pressed), by detecting when the user holds the GND pin with one hand, and presses pin 0, 1, or 2 with the other hand, thus completing a circuit.

Note that this function works best when the BBC micro:bit is powered by AAA battery.

input.pinIsPressed(TouchPin.P0);

Parameters

• name - String; the pin name ("P0", "P1", or "P2")

returns

• Boolean - true if pressed, false if not pressed

Example

This example displays 1 if P0 is pressed, and 0 if P0 is not pressed:

basic.forever(() => {
    if (input.pinIsPressed(TouchPin.P0)) {
        basic.showNumber(1, 150)
    } else {
        basic.showNumber(0, 150)
    }
})
