Tri-Word Game Microbit game code from MEC Bootcamp 2018 created by Kathy Lane and Shawn Grimes as a prototype activity.

Microbit.js

let letter = ""
let timerCounter = 0

//Creates a shake gesture that will display a new letter
input.onGesture(Gesture.Shake, () => {
    if (timerCounter < 63) {
        //Uncomment one of the below depending on what letters you want added to the microbit
        letter = "AEIOUY".charAt(Math.random(6))
        //letter = "BCDFGHJKLMNPQRSTVWXZ".charAt(Math.random(18))
        //letter = "ABCDEFGHIJKLMNOPQRSTUVWXYZ".charAt(Math.random(25))
        
        //Shows the letter on the display
        basic.showString(letter)
    }
})

//Starts a 63 second timer
while (timerCounter < 63) {
    basic.pause(1000) //pauses for 1 second
    timerCounter = timerCounter + 1 /increments the timer counter
}

//Game is over after timer ends so show a skull on the display.
basic.showIcon(IconNames.Skull)
