Place another ||basic:show leds|| block under the heart to make it blink.

basic.showLeds(`
    . # . # .
    # # # # #
    # # # # #
    . # # # .
    . . # . .`);
basic.showLeds(`
    . # . # .
    # . # . #
    # . . . #
    . # . # .
    . . # . .`);

Step 4

Move the blocks inside the ||basic:forever|| to repeat the animation.

basic.forever(() => {
    basic.showLeds(`
        . # . # .
        # # # # #
        # # # # #
        . # # # .
        . . # . .`
        );
    basic.showLeds(`
        . # . # .
        # . # . #
        # . . . #
        . # . # .
        . . # . .`);
})

        # # # # #
        . # # # .

        );
    basic.showLeds(`

        # . # . #
        # . . . #
        . # . # .
        . . # . .`);
    basic.showLeds(`

        . # . # .
        . # # # .
        . . # . .
