CH10-A - Press A & B

For this guide we won't need Maker Tape or any components. We're just going to put the micro:bit into the Bit Board.

We're only going to connect a USB cable and use the built-in A & B buttons on the front of the micro:bit

We'll use the LED Matrix found on the front of the micro:bit as well, to react to our button presses.

If you've never used a micro:bit before you'll want to check out this guide: Bit Board V2 Setup and Use

We're going to load the following code for our Press A & B program: https://makecode.microbit.org/_TFccFteE9...

Notice this code does not have a forever loop! Instead it uses event handlers to react to specific input, in this case, pressing a button.

Once the code is loaded it should start running immediately.

You can power the micro:bit via the USB cable you used to load the code or you can use a battery pack plugged into the Bit Board.

When the code starts it will look like nothing has happened...

Press the A Button to see an "A" on the LED Matrix.

Press the B Button to see a "B" on the LED Matrix.

Now press and release both A and B buttons at the same time and the LED Matrix should clear and show nothing again.
