+# flashing heart blocks activity
+
+Control images with a variable.
+
+### ~avatar avatar
+
+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.
+
+
+```blocks
+basic.forever(() => {
+    basic.showLeds(`
+        . # . # .
+        # # # # #
+        # # # # #
+        . # # # .
+        . . # . .
+        `)
+    basic.pause(500)
+    basic.clearScreen()
+    basic.pause(500)
+
+})
+
+
+
+```

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