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)
})
