Getting started
Are you ready to build cool BBC micro:bit programs?
Here are some challenges for you. Unscramble the blocks in the editor to make real programs that work!
Show LEDs
Use the blocks below to draw something. You can draw another smiley face, or try something else.
basic.showLeds(`
. . . . .
. # . # .
. . . . .
# . . . #
. # # # .
`)
To move your program from your computer to the BBC micro:bit:
- Connect your micro:bit to the computer with the USB cable.
- Click Compile.
- Drag and drop the new file whose name ends in .hex into the MICROBIT window.
- Wait until the yellow light stops blinking!
Show Animation Forever
Show one image after another by snapping blocks together to create an animation (like a cartoon)!

Repeat Forever
Make an animation that never stops with the forever
block.
Unscramble these blocks in the editor to make an animation that first shows a happy face, then an unhappy face, then a happy face, and never stops. You can also change the pictures to make your own animation.
basic.forever(() => {
basic.showLeds(`
. . . . .
. # . # .
. . . . .

`)
basic.showLeds(`

. . . . .
. # # # .
# . . . #
`)
});
Your turn now!
Make your own awesome animation with the show leds
and forever
blocks.
~hint
You can make your animation longer if you use more than two pictures.

Button A and B
In the editor, unscramble the blocks below so that the micro:bit shows
YES when you press button A
and NO when when you press
button B
. All of the blocks under on button A pressed
or on button B pressed
should run when you press that button. For example,
this program will show the word banana
on the LED screen when you
press B
.
input.onButtonPressed(Button.B, () => {
basic.showString("banana");
});
Now try to unscramble these blocks in the editor:
input.onButtonPressed(Button.A, () => {
basic.showString("YES");
});
input.onButtonPressed(Button.B, () => {
basic.showString("NO");
});
Shake
You can find when someone is shaking the BBC micro:bit with the accelerometer (it finds whether the micro:bit is speeding up or slowing down).
Unscramble these blocks in the editor to show a frownie when someone shakes the micro:bit.
input.onGesture(Gesture.Shake, () => {
basic.showLeds(`
. . . . .
. # . # .
. . . . .
. # # # .
# . . . #`);
});
Tilting with gestures
You can also find when someone is tilting the micro:bit left or right, face up or face down, and logo up or logo down (the logo is the yellow oval picture at the top of the board).
Try to build a Rock Paper Scissors game where you turn the micro:bit left to show paper, right to show scissors, and down to show rock.
Unscramble these blocks in the editor and try this program on the micro:bit itself!
input.onGesture(Gesture.TiltLeft, () => {
basic.showLeds(`
# # # # #
# . . . #
# . . . #
# . . . #
# # # # #`);
});
input.onGesture(Gesture.LogoDown, () => {
basic.showLeds(`
. . . . .
. # # # .
. # # # .
. # # # .
. . . . .`);
});
input.onGesture(Gesture.TiltRight, () => {
basic.showLeds(`
# # . . #
# # . # .
. . # . .
# # . # .
# # . . #`);
});
Pins
You can also use the pins as buttons. (The pins are the holes in the big metal bar at the bottom of the board.)
Hold the GND
button with one hand and touch the 0
pin (called
P0
) with your other hand to tell the micro:bit you're pressing it.
Unscramble the blocks in the editor to show a smiley when you press
pin P0
.
input.onPinPressed(TouchPin.P0, () => {
basic.showLeds(`
. . . . .
. # . # .
. . . . .
# . . . #
. # # # .`);
});
Your turn now!
Use the screen, buttons, gestures, and pins to make your own fun game with the BBC micro:bit!
