glowing pendulum block tutorial

The glowing pendulum changes the screen brightness based on the acceleration measured on the micro:bit.

Rebuild the game!

The blocks have been shuffled! Put them back together so that…

• all LEDs are turned on
• the micro:bit repeats code forever that
  • reads the acceleration along the y axis,
  • calculate the absolute value of the acceleration
  • scales down the acceleration value by a factor of 4
  • uses the scaled value to set the screen brightness

    `)
basic.forever(() => {
    let acceleration = input.acceleration(Dimension.Y);
    acceleration = Math.abs(acceleration);
    acceleration = acceleration / 4;
    led.setBrightness(acceleration)
});
