magic 8 activity

Welcome! This activity will help you create a magic 8 ball on the micro:bit. Let's get started!

Show a string to instruct the user how to play Magic 8! The magic 8 ball can only answer true or false questions.

basic.showString("ASK A QUESTION")

Display the number 8.

basic.showString("ASK A QUESTION")
basic.showNumber(8)

Create a condition for when the micro:bit is shaken. Then use the block clear screen to clear the 8 from the display.

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
});

Create a variable of type number called randomNumber. Set randomNumber to a random number with a limit of 2. Remember the random function in the math library, picks a random number from 0 to the limit, but not including the limit unless it is 0.

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
    let randomNumber = Math.random(3)

});

Create an if statement for the condition if randomNumber = 2. If randomNumber is 2, display the string 'Yes'

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () =>  {
    basic.clearScreen();
    let randomNumber = Math.random(3);
    if (randomNumber == 2) {
        basic.showString("YES");
    }
});

Create an if statement for the condition if randomNumber = 1. If randomNumber is 1, display the string 'No'

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () => {
    basic.clearScreen()
    let randomNumber = Math.random(3)
    if (randomNumber == 2) {
        basic.showString("YES")
    } else if (randomNumber == 1) {
        basic.showString("NO")
    }
})

If randomNumber is not 2 or 1, it must be 0. This is the else condition. If randomNumber is 0, display the string 'I don't know'

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () =>  {
    basic.clearScreen()
    let randomNumber = Math.random(3)
    if (randomNumber == 2) {
        basic.showString("YES")
    } else if (randomNumber == 1) {
        basic.showString("NO")
    } else {
        basic.showString("I DON'T KNOW")

    }

})

Display the number 8 so users know they can ask the magic 8 ball another question!

basic.showString("ASK A QUESTION")
basic.showNumber(8)
input.onGesture(Gesture.Shake, () =>  {
    basic.clearScreen()
    let randomNumber = Math.random(3)
    if (randomNumber == 2) {
        basic.showString("YES")
    } else if (randomNumber == 1) {
        basic.showString("NO")
    } else {
        basic.showString("I DON'T KNOW")
    }
    basic.showNumber(8)

})
