+
+Coding challenges for the digital pet tutorial. 
+
+## Before we get started
+
+Complete the following guided tutorial:
+
+* [tutorial](/lessons/digital-pet/tutorial)
+
+At the end of the tutorial, click `keep editing`. Your code should look like this:
+
+```
+basic.forever(() => {
+    if (input.buttonIsPressed("A")) {
+        setSleep()
+        basic.pause(5000)
+    } else {
+        setAwake()
+    }
+})
+```
+
+### Challenge 1
+
+Now let's feed the pet! Add an **ELSE IF** statement that checks if button `B` is pressed. Click on the **ELSE** and type **IF** next to it to get the **ELSE IF**.
+
+```
+basic.forever(() => {
+    if (input.buttonIsPressed("A")) {
+        setSleep()
+        basic.pause(5000)
+    } else if (input.buttonIsPressed("B")) {
+
+    }
+    else {
+        setAwake()
+    }
+})
+```
+
+### Challenge 2
+
+### @video td/videos/digital-pet-2
+
+Now we want to show your eating pet! Let's create a function called `set eat` that will do create an image. Store that image in a variable and then show it.
+
+```
+export function setEat() {
+    let img = images.createImage(`
+. # . # .
+. . # . .
+. . # . .
+. # . # .
+. . # . .
+`)
+    img.showImage(0)
+}
+```
+
+Once you create the function `set eat`, call it in the **ELSE IF** statement that checks if button `B` is pressed.
+
+```
+basic.forever(() => {
+    if (input.buttonIsPressed("A")) {
+        setSleep()
+        basic.pause(5000)
+    } else if (input.buttonIsPressed("B")) {
+        setEat()
+    }
+    else {
+        setAwake()
+    }
+})
+```
+
+### Challenge 3
+
+### @video td/videos/digital-pet-3
+
+Have your pet tell you when it is going to sleep! Do this inside of the **IF** statement that checks if button `A` is pressed before you call the function `set sleep`.
+
+```
+basic.forever(() => {
+    if (input.buttonIsPressed("A")) {
+        basic.showString("I am going to sleep.", 150) // ***
+        setSleep()
+        basic.pause(5000)
+    } else if (input.buttonIsPressed("B")) {
+        setEat()
+    }
+    else {
+        setAwake()
+    }
+})
+```
+
+### Challenge 4
+
+### @video td/videos/digital-pet-4
+
+Now, how about we keep track of how many times our pet eats? Add a global variable  called `feed` that keeps track of how many times you feed your pet. If button `B` is pressed, increment `feed` by one.  Add a condition `on shake` to check your total.
+
+```
+feed = 0 // ***
+basic.forever(() => {
+    if (input.buttonIsPressed("A")) {
+        basic.showString("I am going to sleep.", 150)
+        setSleep()
+        basic.pause(5000)
+    } else if (input.buttonIsPressed("B")) {
+        feed = feed + 1 // ***
+        setEat()
+    }
+    else {
+        setAwake()
+    }
+})
+input.onGesture(Gesture.Shake, () => {
+    basic.showNumber(feed, 150) // ***
+}) // ***
+```
+
+### Challenge 5
+
+Program your pet to say that it is hungry after 60 seconds.
+
+**Hint**: use `input->running time`
+
