# Code

|
|
## Step 1: Add the Kitronik package
|
|
|
|
Kitronik has a package with blocks that program their motor driver. We need to add it to our project.
|
|
|
|
* Click on **Advanced**
|
|
* Click **Add Package**
|
|
* Type ``kitronik``, press **Enter**
|
|
* Select the **kitronik-motor-driver** package
|
|
|
|
After the package is loaded, you should see a new **Kitronik** category in the toolbox.
|
|
|
|
## Step 2: Round and round we go!

|
|
The first program has the car drive around in a circle for 5 seconds when the user presses the ``A`` button. This is simply done by turning both motor controllers on for 5 seconds.
|
|
|
|
```blocks-ignore
|
|
input.onButtonPressed(Button.A, () => {
|
|
basic.showIcon(IconNames.Happy)
|
|
kitronik.motorOn(kitronik.Motors.Motor1, kitronik.MotorDirection.Reverse, 100)
|
|
kitronik.motorOn(kitronik.Motors.Motor2, kitronik.MotorDirection.Forward, 100)
|
|
basic.pause(5000)
|
|
kitronik.motorOff(kitronik.Motors.Motor1)
|
|
kitronik.motorOff(kitronik.Motors.Motor2)
|
|
basic.showIcon(IconNames.SmallDiamond)
|
|
})
|
|
```
|
|
|
|
### ~ hint
|
|
|
|
**Protect your electronics**
|
|
|
|
Make sure to unplug the @boardname@ from the edge connector when you're connecting it to your computer. This helps protect everything from potential electrical problems.
|
|
|

|
|
|
Depending on how your wires are connected to the motor driver, your car may go backward instead of forward. If so, you can either swap the wires or change the ``MotorDirection`` in your code to get it to go the right way.
|
|
|
|
## Step 3: Figure eight
|
|

|
|
|
Instead of stopping after 5 seconds, we reverse the steering motor to turn in the other direction. This will create a figure eight path.
|
|
|
|
```blocks-ignore
|
|
input.onButtonPressed(Button.A, () => {
|
|
basic.showIcon(IconNames.Happy)
|
|
kitronik.motorOn(kitronik.Motors.Motor1, kitronik.MotorDirection.Reverse, 100)
|
|
kitronik.motorOn(kitronik.Motors.Motor2, kitronik.MotorDirection.Forward, 100)
|
|
basic.pause(3500)
|
|
kitronik.motorOn(kitronik.Motors.Motor2, kitronik.MotorDirection.Reverse, 100)
|
|
basic.pause(3500)
|
|
kitronik.motorOff(kitronik.Motors.Motor1)
|
|
kitronik.motorOff(kitronik.Motors.Motor2)
|
|
basic.showIcon(IconNames.SmallDiamond)
|
|
})
|
|
```
|
|
|
|
Great! The code to drive the car is done! Now let's get another @boardname@ and control the car remotely.
