# flashing heart

### ~avatar avatar

Use the LEDs to display a flashing heart, and then create
an animation of a broken heart. :(

### ~

## Step 1

Use [show leds](/reference/basic/show-leds) and make your code look like this:

```blocks
basic.showLeds(`
    . # . # .
    # # # # #
    # # # # #
    . # # # .
    . . # . .`
    );
```

## Step 2

Add a [pause](/reference/basic/pause) to wait and [clear screen](/reference/basic/clear-screen) to turn off the LEDs.

```blocks
basic.showLeds(`
    . # . # .
    # # # # #
    # # # # #
    . # # # .
    . . # . .`);
basic.pause(500);
basic.clearScreen();
```

## Step 3

Put a [forever loop](/reference/basic/forever) around it.

```blocks
basic.forever(() => {
basic.showLeds(`
    . # . # .
    # # # # #
    # # # # #
    . # # # .
    . . # . .`
    );
basic.pause(500);
basic.clearScreen();
})
```

## Step 4

Add a [pause](/reference/basic/pause) to wait after clearing the screen.

```blocks
basic.forever(() => {
basic.showLeds(`
    . # . # .
    # # # # #
    # # # # #
    . # # # .
    . . # . .`
    );
basic.pause(500);
basic.clearScreen();
basic.pause(500);
})
```

## Step 5

Add a second image of a broken heart. 


```blocks
basic.forever(() => {
basic.showLeds(`
    . # . # .
    # # # # #
    # # # # #
    . # # # .
    . . # . .`
    );
basic.pause(500);
basic.clearScreen();
basic.pause(500);
basic.showLeds(`
    . # . # .
    # . # # #
    # . . . #
    . # # # .
    . . # . .`
    );
basic.pause(500);
basic.clearScreen();
basic.pause(500);
})
```
