In this project we're going to record some of our own sounds and add them to the Racing Car project.

If you completed the Racing Car project in the Driving and Traffic Lights pack then open your completed project in Scratch. We'll add the sound effects to your project.

If you haven't completed this project then you can use this starter project which has the Racing Car code already completed.

The first change we're going to make is to turn down the volume from 100% and set it to 30%.

Add the set volume to 30 % block to the car sprite, underneath the point in direction 90 block.

when green flag clicked set size to (10) % go to x:(0) y:(0) point in direction (90) set volume to (30) % // add this block here forever if < touching color [#3db000]? > then set [speed v] to (2) else set [speed v] to (6) end if < key [up arrow v] pressed? > then move (speed) steps end if < key [down arrow v] pressed? > then move (-2) steps end if < key [left arrow v] pressed? > then turn ccw (5) degrees end if < key [right arrow v] pressed? > then turn cw (5) degrees end end

The first sound we are going to record and add to the project is the race starter saying the words "On your marks, get set, go!".

Record a new sound of you saying "On your marks, get set, go!".

Once you've recorded it, rename the sound from "recording1" to "on your marks".

Using the microphone on your computer you can record sounds and add them to your Scratch project.

To record a sound in Scratch follow these steps:

1. Click on the Sounds tab on the top left.
2. Put your mouse over the Choose a Sound button.
3. Click on Record.
4. Your web browser might ask if it can have permission to use your microphone, if it does click Yes or Allow.
5. A Record Sound box will appear, to start recording click the orange circle (Record).
6. When you are finished recording click the orange square (Stop recording).
7. You can trim your recording and play it back if you want.
8. Click on the Save button to save your recording. You can now use it in your project by selecting it in a sound block.

Now that you've recorded the sound, make it play at the start by adding the play sound [on your marks] until done block underneath the set volume to 30 % block.

when green flag clicked set size to (10) % go to x:(0) y:(0) point in direction (90) set volume to (30) % play sound (on your marks v) until done // add this block here forever if < touching color [#3db000]? > then set [speed v] to (2) else set [speed v] to (6) end if < key [up arrow v] pressed? > then move (speed) steps end if < key [down arrow v] pressed? > then move (-2) steps end if < key [left arrow v] pressed? > then turn ccw (5) degrees end if < key [right arrow v] pressed? > then turn cw (5) degrees end end

Click on the green flag and test that your sound plays OK. Notice that you can't make your car move until the sound has finished playing.

The next sound we are going to record and add to the project is the sound of the engine.

Record a new sound of you making an engine noise. Use the trim tool to make it a VERY short sound as it will be playing over and over again quickly as your car moves forwards.

Once you've recorded it, rename the sound from "recording1" to "engine".
