# 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.
|
||
|
|
|
||
|
|
```sig
|
||
|
|
input.pinIsPressed(TouchPin.P0);
|
||
|
|
```
|
||
|
|
|
||
|
|
### Parameters
|
||
|
|
|
||
|
|
* name - [String](/microbit/reference/types/string); the pin name ("P0", "P1", or "P2")
|
||
|
|
|
||
|
|
### returns
|
||
|
|
|
||
|
|
* [Boolean](/microbit/reference/types/boolean) - `true` if pressed, `false` if not pressed
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
This example displays 1 if P0 is pressed, and 0 if P0 is not pressed:
|
||
|
|
|
||
|
|
```blocks
|
||
|
|
basic.forever(() => {
|
||
|
|
if (input.pinIsPressed(TouchPin.P0)) {
|
||
|
|
basic.showNumber(1, 150)
|
||
|
|
} else {
|
||
|
|
basic.showNumber(0, 150)
|
||
|
|
}
|
||
|
|
})
|
||
|
|
```
|
