# 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 = randint(0, 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 = randint(0, 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 = randint(0, 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 = randint(0, 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 = randint(0, 3)
if (randomNumber == 2) {
basic.showString("YES")
} else if (randomNumber == 1) {
basic.showString("NO")
} else {
basic.showString("I DON'T KNOW")
}
basic.showNumber(8)

})``````

Excellent, you’re ready to continue with the challenges!
