ProjectSMART Pedometer Tutorial -- Level 1

Step 1

On your screen, you see two blue blocks. They say ||Basic:on start|| and ||Basic:forever||.

(Hint: Click Next to go to the next step)

Step 2

The ||Basic:on start|| block tells the @boardname@ what to do when it first starts. We don't need it for this project. Click the ||Basic:on start|| block then press the delete key (or the Backspace key) on your keyboard.

Step 3

The ||Basic:forever|| block tells the @boardname@ a list of things to do forever. The program will go through the list, and when it is done, it will repeat the list, over and over again.

Step 4

The way our timer will work is to start counting when you press a button, and to stop counting when we press another button. We'll go over the details in later steps.

Step 5

On the left below, you can see the set of things that you can make your @boardname@ do. The @boardname@ can do a lot, but we're hiding some from you for now.

Step 6

The first thing we want our @boardname@ to do is to show the number of steps counted. Click on the stick figure and look at the choices. Drag the ||moveSMART:show timer|| block onto the screen and place it inside the mouth of the ||Basic:forever|| block.

After you try, you can click on the blue lightbulb in the circle (over on the right) to check to see if you did it correctly.

basic.forever(function () {
    moveSMART.showTimer()
})

Step 7

Look at the picture of the @boardname@ on the left. You should see it now show "0" on the display. This is because we haven't started the timer yet. (You can delete the ||moveSMART:show timer|| block and the 0 will disappear. But be sure to put it back!)

Step 8

Next, we need to figure out how to start the timer. Look at the picture on the left. The @boardname@ has two buttons: A and B (the black circles next to the A and the B in the triangle). When you press A, we'll start the timer. When you press B, we'll stop the timer.

Step 9

Click on the pink target (it says Input on the right). Look for the ||input:on button A pressed|| block. Drag it to your workspace.

input.onButtonPressed(Button.A, function () {
	
})

Step 10

Now look inside the moveSMART menu for the ||moveSMART:start timing|| block. Drag it inside the mouth of the ||input:on button A pressed|| block.

input.onButtonPressed(Button.A, function () {
    moveSMART.startTiming()
})

Step 11

Try this one on your own first. Tell the @boardname@ to stop counting steps when you press the B button.

Hint: create another ||input:on button A pressed|| block. Then look for where it says "A" and change it to "B".

Step 12

Did you get it? You should have dragged the ||input:on button A pressed|| block to your workspace and clicked the triangle next to A. Then choose B. Then drag the ||moveSMART:stop timer|| block inside the mouth of the ||input:on button B pressed|| block.

input.onButtonPressed(Button.B, function () {
    moveSMART.stopTiming()
})

Step 13

Look at the picture of the @boardname@ on your screen again. To see how the timer works, we can press the pretend buttons on the picture of the @boardname@.

Click Next to go to the next step

Step 14

To start counting, press the A button (the black circle next to the A in the triangle). The @boardname@ will start the timer, so you will see the number on the @boardname@ increase. To stop the timer, press the B button, and the number will stay there.

When the number is bigger than 9, it doesn't fit on the small set of LEDs, so the @boardname@ will make the number scroll.

Step 15

Now, we want to transfer the code onto the real @boardname@. Watch the video Transferring your program to the BBC micro:bit.

  1. Make sure your @boardname@ is connected to your computer using the USB cable.
  2. Press the |Download| on the bottom left.
  3. Click Pair Device (it's in a gray button).
  4. Click the purple Pair Device button. In the window that appears, select the @boardname@ device (It should start with "BBC micro:bit...") Click the Connect button.
  5. Now click the purple |Download| button again.

You should see the lights on your @boardname@ flashing.

Step 15

Press the buttons on your real @boardname@. Does it work? If you want to reset your timer to 0, press the reset button on the back of the @boardname@.

Now head back into the tutorial webpage. You should still have it open in a tab in your browser.
