Look at the simulator and check that your image is showing on the screen. When you are ready, press the **DOWNLOAD** button
and follow the instructions to transfer your code on the brick.
## Step 4 - Steer motors @fullscreen
## Step 4 - Pause on Start @fullscreen
As you may have noticed, the code starts running immediately once you download it to the brick. To prevent the robot
from rolling away, add a ``||brick:pause until enter pressed||`` button to wait for the user to press enter.
```blocks
brick.showMood(moods.neutral)
brick.buttonEnter.pauseUntil(ButtonEvent.Pressed)
```
## Step 5 - Steer motors @fullscreen
Drag a ``||motors:steer motors||`` block from the **MOTORS** toolbox drawer and snap it in under ``||brick:show mood||``.
Click on the **(+)** symbol and make sure to tell your motors to turn **1** rotation.
```blocks
brick.showMood(moods.neutral)
brick.buttonEnter.pauseUntil(ButtonEvent.Pressed)
motors.largeBC.steer(0, 50, 1, MoveUnit.Rotations)
```
## Step 5 - Try your code @fullscreen
## Step 6 - Try your code @fullscreen
Whenever you make a code change, the simulator will restart so you can see what your latest change will do.
When you are ready, click **DOWNLOAD** and follow the instructions to transfer the code into your brick.
