ledScreen.display
Inside of the light array you will use a 1 or 0 in each parameter to turn on or off the LED lights. The array is organized from the 5 Lines of 5 parameters with each light turned on when the block is first used in the code. In order to turn off individual LEDs, replace the 1 with a 0.
Examples
Diamond
Using ledscreen.display(boardArray) creates a diamond shape in the micro:bit board. Think of other shapes you can create using this
ledScreen.display([
([0, 0, 1, 0, 0]),
([0, 1, 1, 1, 0]),
([1, 1, 1, 1, 1]),
([0, 1, 1, 1, 0]),
([0, 0, 1, 0, 0])
]);
Beating Heart
ledscreen.display(boardArray) and two onBoardEvents with the A Button to create a beating heart animation.
onBoardEvent(buttonA, "up", function() {
ledScreen.display([
([0, 1, 0, 1, 0]),
([1, 1, 1, 1, 1]),
([1, 1, 1, 1, 1]),
([0, 1, 1, 1, 0]),
([0, 0, 1, 0, 0])
]);
});
onBoardEvent(buttonA, "down", function() {
ledScreen.display([
([0, 0, 0, 0, 0]),
([0, 1, 0, 1, 0]),
([0, 1, 1, 1, 0]),
([0, 0, 1, 0, 0]),
