# flashing heart challenges Coding challenges for flashing heart. ## Before we get started Complete the [flashing heart](/microbit/lessons/flashing-heart/activity) activity and your code will look like this: ``` basic.forever(() => { basic.plotImage(` . # . # . # # # # # # # # # # . # # # . . . # . . `) basic.pause(500) basic.clearScreen() basic.pause(500) }) ``` ### Challenge 1 ### @video td/videos/flashing-heart-1 Let's plot a different image. Let's display a broken heart! To do this, you need to **add a line** between the last line and the end loop. Plot the image of the broken heart and then add a pause of 500 milliseconds. ``` basic.forever(() => { basic.plotImage(` # # . # # # # # # # # # # # # . # # # . . . # . . `) basic.pause(500) basic.clearScreen() basic.pause(500) basic.plotImage(` . # . # . # . # # # # . . # # . # # # . . . # . . `) // *** basic.pause(500) // *** }) ``` * click `run main` to see if the code works as expected. ### Challenge 2 ### @video td/videos/flashing-heart-2 Now let's alternate flashing the heart and the broken heart. To do this, we need to clear the screen and then add a pause of 500 milliseconds under the new code we added in Challenge 1. ``` basic.forever(() => { basic.plotImage(` # # . # # # # # # # # # # # # . # # # . . . # . . `) basic.pause(500) basic.clearScreen() basic.pause(500) basic.plotImage(` . # . # . # . # # # # . . # # . # # # . . . # . . `) basic.pause(500) basic.clearScreen() // *** basic.pause(500) // *** }) ``` * click `run main` to see if the code works as expected. ### Challenge 3 You now have a heart and broken heart flashing! Now plot a new image to alternate in with the heart and broken heart.
