Congratulations! You have made your own Ice King or Princess Bubblegum Crown! Move on to the next section to code your crown.

Code

Code your Crown to play a sound and show an animation when you tilt your head to the left or right.

Concepts

  • Motion Sensor, or Accelerometer (shake)
  • Animation
  • Pixels
  • Sound

Blocks

light.setAll(0xff8000)
light.showAnimation(light.theaterChaseAnimation, 2000)
music.playSound(music.sounds(Sounds.Wawawawaa))
input.onGesture(Gesture.Shake, function () {})

Step 1: Turn on all lights red or blue

  • Open MakeCode in your web browser
  • Click on New Project

New Project button on Home Page

  • Name your project as “Crown” (note – you don’t need to click the Save button, just type the name).

Name the project as "Crown"

  • From the ||loops:LOOPS|| Toolbox drawer, drag out an ||loops:on start|| block to the coding Workspace (note – you can ignore or delete the existing Forever block on the workspace. Delete blocks by dragging them back over to the Toolbox menu).

  • From the ||light:LIGHT|| Toolbox drawer, drag out a ||light:set all pixels|| block to the Workspace, and drop it into the ||loops:on start|| block.

'set all pixels' block in 'on start'

  • If you are making the Ice King crown, leave the default Red color. If you are making Princess Bubblegum’s crown, then in the ||light:set all pixels|| block, click on the color and select a Blue color.

Step 2: Add two blocks for tilting your head left and right

  • From the ||input:INPUT|| Toolbox drawer, drag out two ||input:on shake|| block onto the Workspace.

Two 'on shake' blocks in workspace

  • In the ||input:on shake|| blocks, use the drop-down menus to select tilt right for one block and tilt left for the other.

Gesture selection for 'on shake' block

Step 3: Play a Sound

  • From the ||music:MUSIC|| Toolbox drawer, drag out two ||music:play sound|| blocks to the coding Workspace, and drop one each into the ||input:on tilt left|| and ||input:on tilt right|| blocks.

'play sound' blocks inserted into the 'on tilt` blocks

  • In the ||music:play sound|| blocks, use the drop-down menus to select different sound effects. Note, you can test the sounds in the Simulator by moving your mouse over the left and right sides of the Circuit Playground Express.

Step 4: Show an animation

  • From the ||light:LIGHT|| Toolbox drawer, drag out two ||light:show animation|| blocks to the coding Workspace, and drop one each into the ||input:on tilt left|| and ||input:on tilt right|| blocks, right after the ||music:play sound|| blocks.
  • In the ||light:show animation|| blocks, click on the animation drop-down menu to select your preferred animations.

Your final program may look something like this:

light.setAll(0x00ffff)
input.onGesture(Gesture.TiltLeft, function () {
    music.playSound(music.sounds(Sounds.JumpUp))
    light.showAnimation(light.rainbowAnimation, 2000)
})
input.onGesture(Gesture.TiltRight, function () {
    music.playSound(music.sounds(Sounds.JumpDown))
    light.showAnimation(light.cometAnimation, 2000)
})

Step 5: Download

Test your program in the Simulator by moving your mouse over the left and right sides of the board.
