        # Moto:bit

![SparkFun Moto:bit](https://raw.githubusercontent.com/sparkfun/pxt-moto-bit/master/icon.png)  

The package adds support for the **moto:bit** add-on board from SparkFun.

TODO: To use this package, go to https://pxt.microbit.org, click ``Add package`` and search for **moto-bit**.

### ~ hint

Not currently integrated into pxt.  It must be manually added.  This package is still under development and subject to changes.

## Usage

The package adds support for the **moto:bit** add-on board from SparkFun.

* [moto:bit](https://www.sparkfun.com/products/14213)

* [Shadow Chasis](https://www.sparkfun.com/products/13301)

* [Hobby Gearmotor](https://www.sparkfun.com/products/13302)

* [Wheel Pair](https://www.sparkfun.com/products/13259)

* [RedBot Sensor - Line Follower](https://www.sparkfun.com/products/11769)

* [ine Follower Array](https://www.sparkfun.com/products/13582)

* [RedBot Sensor - Mechanical Bumper](https://www.sparkfun.com/products/11999)

* [Servo Extention Cable](https://www.sparkfun.com/products/13164)

### Micro:bit Pins Used 

The following micro:bit pins are used for analog and digital sensors, motor driving:  

* ``P0`` -- Analog Input 0

* ``P1`` -- Analog Input 1

* ``P2`` -- Analog Input 2

* ``P8`` -- Digital Input/Output

* ``P12`` -- Digital Input/Output 

* ``P14`` -- Digital Input/Output

* ``P15`` -- Servo Motor

* ``P16`` -- Servo Motor

* ``P19`` -- motor driver - SCL

* ``P20`` -- motor driver - SDA 

### Set Motor Speed

To set the speed and direction for a motor, place the `|set motor|` block.

The block takes three parameters: motor select, direction, and speed.

* The motor select must be either `Left` or `Right`

* Direction must be either `Forward` or `Reverse`

* Speed is an integer value between `0` and `100`

```blocks

motobit.setMotorSpeed(Motor.Left, MotorDirection.Forward, 50)

```

### Invert Motor Directon

When a motor turns opposite to the direction that was declared, the `invert` 

block may be used. The block accepts two parameters: motor select, and a 

boolean variable. When the boolean is set to `true`, the motor direction is 

inverted so that `Forward` no longer causes the motor to spin in `Reverse`, 

but rather `Forward`.

* The motor select must be either `Left` or `Right`

* Invert must be either `true` or `false`

```blocks

motobit.invert(Motor.Left, true)

```

### Enabling Motors

Regardless of the set motor speed, before the motors will turn on the switch on moto:bit

must be set to **"Run Motors"**, and the enable motors command must be set to `ON`

* Motor enable must be either `On` or `Off`.

```blocks

motobit.enable(MotorPower.On)

```

## Examples

### Example: Receiving a packet of data over wireless

The following program reads a string to control the direction of two motors.

```blocks

radio.onDataPacketReceived( ({ receivedNumber }) =>  {

    // Drive forward

    if (receivedNumber == 128) {

        led.plot(2, 0)

        motobit.setMotorSpeed(Motor.Left, MotorDirection.Forward, 50)

        motobit.setMotorSpeed(Motor.Right, MotorDirection.Forward, 50)

        motobit.enable(MotorPower.On)

    } else {

        led.unplot(2, 0)

    }

    // Turn left

    if (receivedNumber == 64) {

        led.plot(0, 2)

        motobit.setMotorSpeed(Motor.Left, MotorDirection.Reverse, 50)

        motobit.setMotorSpeed(Motor.Right, MotorDirection.Forward, 50)

        motobit.enable(MotorPower.On)

    } else {

        led.unplot(0, 2)

    }

    // Turn right

    if (receivedNumber == 32) {

        led.plot(4, 2)

        motobit.setMotorSpeed(Motor.Left, MotorDirection.Forward, 50)

        motobit.setMotorSpeed(Motor.Right, MotorDirection.Reverse, 50)

        motobit.enable(MotorPower.On)

    } else {

        led.unplot(4, 2)

    }

    // Drive in reverse

    if (receivedNumber == 16) {

        led.plot(2, 4)

        motobit.setMotorSpeed(Motor.Left, MotorDirection.Reverse, 50)

        motobit.setMotorSpeed(Motor.Right, MotorDirection.Reverse, 50)

        motobit.enable(MotorPower.On)

    } else {

        led.unplot(2, 4)

    }

    // Stop

    if (receivedNumber == 0) {

        motobit.enable(MotorPower.Off)

    }

})

radio.setGroup(13)

```
