# Button Is Pressed
|
|
|
|
Get the state of an input button. The micro:bit has two input buttons: A and B.
|
|
|
|
```sig
|
|
input.buttonIsPressed(Button.A);
|
|
```
|
|
|
|
### Parameters
|
|
|
|
* name - [String](/microbit/reference/types/string); input button "A", "B", or "A+B" (both input buttons)
|
|
|
|
### Returns
|
|
|
|
* [Boolean](/microbit/reference/types/boolean) - `true` if pressed, `false` if not pressed
|
|
|
|
### Example
|
|
|
|
The following code uses an [if](/microbit/reference/logic/if) statement to run code, depending on whether or not the A button is pressed:
|
|
|
|
```blocks
|
|
basic.forever(() => {
|
|
let pressed = input.buttonIsPressed(Button.A)
|
|
if (pressed) {
|
|
// this code runs if the A button is pressed
|
|
basic.showNumber(1, 150)
|
|
} else {
|
|
// this code runs if the A button is *not* pressed
|
|
basic.showNumber(0, 150)
|
|
}
|
|
})
|
|
```
