+
+Coding challenges for the answering machine tutorial. 
+
+## Before we get started
+
+Complete the [answering machine](/microbit/lessons/answering-machine/activity) activity and your code will look like this:
+
+```blocks
+basic.showString("ASK ME A QUESTION")
+```
+
+### Challenge 1
+
+### @video td/videos/answering-machine-1
+
+Now we need to reply after someone asks micro:bit a  yes or no question. We want to respond `YES` when button `A` is pressed. Add a condition for button `A` and inside it show the string `YES`.
+
+```blocks
+basic.showString("ASK ME A QUESTION")
+input.onButtonPressed(Button.A, () => {
+    basic.showString("Yes")
+})
+
+```
+
+* `Run` the code to see if it works as expected.
+
+### Challenge 2
+
+### @video td/videos/answering-machine-2
+
+What if micro:bit's answer to the question is no? Let's have `NO` be displayed when button `B` is pressed. Add a condition for button `B` and inside it show the string `NO`.
+
+```blocks
+basic.showString("ASK ME A QUESTION")
+input.onButtonPressed(Button.A, () => {
+    basic.showString("Yes")
+})
+input.onButtonPressed(Button.B, () => {
+    basic.showString("NO")
+})
+
+```
+
+* `Run` the code to see if it works as expected.
+
+**Challenge 3**
+
+When you are asked a yes or no question, do you always say yes or no? Add a condition for `on shake` that displays `MAYBE`.
+
