For information about DC motors by Kittenbot, please visit: [Kittenbot Actuators](https://kittenbothk-eng.readthedocs.io/en/latest/motors/index.html)

**Sample Program:**

Connect 2 DC motors to the M1A and M1B port of the Robotbit Edu.

```
The speed of motor ranges from -255 to 255.
```

#### 2. Programming Servos

For information about servos by Kittenbot, please visit: [Kittenbot Actuators](https://kittenbothk-eng.readthedocs.io/en/latest/motors/index.html)

**Sample Program:**

Connect a servo to the S1 port of Robotbit Edu.

```
Connect the orange wire from the servo to the yellow wire of the Robotbit.
```

#### 3. Programming Stepper Motors

For information about DC motors by Kittenbot, please visit: [Kittenbot Actuators](https://kittenbothk-eng.readthedocs.io/en/latest/motors/index.html)

```
The programming blocks were designed for Kittenbot's 28BY-48-5V stepper motor, using other motors may result in reduced accuracy.
```

**Sample Program:**

Connect Stepper Motors to the M1 and M2 port of the Robotbit Edu, with the red wire connecting to the VM port.

![](https://kittenbothk-eng.readthedocs.io/en/latest/_images/stepper_wire1.png)

```
Stepper Motors have a rotation range of -360 to 360.
```

```
Remember to add a "Show" block to display the effect.(Except show color.)
```

**4.1 Lighting up all lights**

**4.2 Customizing color with RGB**

```
RGB value has a range of 0-255.
```

**4.3 Customizing color with HSL.**

```
HSL consists of a hue value with the range 0-360, a sturation and brightness value with the range 0-100.
```

**4.4 Lighting up individual lights**

```
The lights are labelled 0-3. (As labelled on the Robotbit)
```

**4.5 Adjusting the brightness.**

```
The brightness level has a range of 0-255.
```

#### 5. Programming the IO Pins

The blocks for the IO pins are found in the Pins tab.

```
Pin 0-2 can be used as analog pins while P8, P12~P15 can only be used as digital pins.
Analog values have a range of 0 to 1023, digital values have a range of 0 to 1.
```

![](https://kittenbothk-eng.readthedocs.io/en/latest/_images/robotbit_pin1.png)

**5.1 Reading values from pins**

```
Pin 0 is occupied by the buzzer by default, the jumper should be removed when using this pin.
```

**5.2 Writing values to pins**

```
Pin 0 is occupied by the buzzer by default, the jumper should be removed when using this pin.
```
