Spiel: Neopixel

1. The Calliope mini is rotated in different directions.
2. The rotations are detected by the Calliope mini's position sensor. Rotations on the x-axis switch on the first LEDs up to half of the strip and rotations on the y-axis switch on the second half.
3. For an increased difficulty level, a random LED is switched off every second.
4. Leuchten alle LEDs des Streifens, ist das Spiel gewonnen und es erscheint ein Regenbogen.

Programming is carried out in the MakeCode Editor, and the "NeoPixel ” extension must also be loaded.

Code

Configuration of the NeoPixel strip

• The first block determines the length and the connection of the NeoPixel strip.
• The two “Interval” blocks divide the strip into two areas and enable the division for the x and y directions of rotation.

Determination of the LED by the position sensor

• The values of the position sensor are distributed over a specific area of the NeoPixel and stored in a variable.
• For clarity, half is divided again to cover negative (-90° to 0°) and positive (0° to 90°) rotation angles.

List

• The previously saved variable can be saved in a list to determine when all LEDs are switched on.

switch off random pixels

• Every second, an LED is switched off to make the game a little more difficult. To do this, a random value is removed from the list and the corresponding LED is switched off.
