If you press button A, the program will show the arrow pointing up, which starts 0 LEDs from the left in the big image. If you press button B, the program will show the arrow pointing down, which starts 5 LEDs from the left.
let arrows = images.createBigImage(` . . # . . . . # . . . # # # . . . # . . # . # . # # . # . # . . # . . . # # # . . . # . . . . # . . `); input.onButtonPressed(Button.A, () => { arrows.showImage(0); }); input.onButtonPressed(Button.B, () => { arrows.showImage(5); });
