answering machine blocks challenges

Coding challenges for the answering machine tutorial.

Before we get started

Complete the answering machine activity and your code will look like this:

basic.showString("ASK ME A QUESTION")

Challenge 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.

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

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.

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.
