# On Pin Released

Start an [event handler](/reference/event-handler) (part of the
program that will run when something happens, like when a button is
pressed).  This handler works when you release pin `0`, `1`, or `2`
together with `GND`.  When you are using this function in a web
browser, click and release the pins on the screen instead of the ones on the BBC
micro:bit.

If you hold the `GND` pin with one hand and touch pin `0`, `1`, or `2`
with the other, a very small (safe) amount of electricity will flow
through your body and back into the micro:bit. This is called
**completing a circuit**. It's like you're a big wire!

```sig
input.onPinReleased(TouchPin.P0, () => {
})
```

## ~hint

This function works best when the BBC micro:bit is using batteries for power,
instead of the USB cable.

## Parameters

* ``name`` means the pin that is being released, either `P0`, `P1`, or `P2`

### Example: pin pressed counter

This program counts how many times you release the `P0` pin. 
Every time you release the pin, the program shows the number of times on the screen.

```blocks
let count = 0
basic.showNumber(count, 100)
input.onPinReleased(TouchPin.P0, () => {
    count = count + 1
    basic.showNumber(count, 100)
})
```
