In this activity, you will learn how to blink an image on the LED screen.
### ~
Let's start by adding code that plots a heart image on the screen using `show LEDs`. Once you are done coding, don't forget to run your code in the simulator or the micro:bit.
```blocks
basic.showLeds(`
. # . # .
# # # # #
# # # # #
. # # # .
. . # . .`);
```
We want to leave the image on the screen for 0.5 seconds (500 milliseconds), then clear the screen. We can use `pause` to wait and `clear screen` to turn off the LEDs.
```blocks
basic.forever(() => {
basic.showLeds(`
. # . # .
# # # # #
# # # # #
. # # # .
. . # . .
`)
basic.pause(500)
basic.clearScreen()
})
```
Finally, we can surround this code with a `forever` loop to repeat it and add a pause after `clear screen` to keep the screen off for a little while. Modify your code so that your code looks like this.
