# Power Functions IR Sender
[](https://travis-ci.org/philipphenkel/pxt-powerfunctions)
Control your LEGO® Power Functions motors using your micro:bit or Calliope-Mini, an infrared LED and MakeCode.
This extension turns your device into a remote control for your Power Functions devices.
A project using this extension is documented on [hackster.io](https://www.hackster.io/philipp-henkel/lego-power-functions-ir-sender-for-micro-bit-aecc10)
## Installation
Open MakeCode and select '+ Extensions' in the 'Advanced' menu. You need to enter our project URL https://github.com/philipphenkel/pxt-powerfunctions in the search field, hit return and then select the powerfunctions extension.
# Documentation
## powerfunctions.connectIrLed
Configures the infrared LED pin. A 940 nm emitting diode is required.
```sig
powerfunctions.connectIrLed(AnalogPin.P0)
```
### Parameters
- `pin` - analog pin with an attached IR-emitting LED
## powerfunctions.setSpeed
Sets the speed of a motor.
```sig
powerfunctions.setSpeed(PowerFunctionsMotor.Red1, 3)
```
### Parameters
- `motor` - the motor
- `speed` - the speed of the motor from `-7` to `7`.
## powerfunctions.brake
Brakes then float. The motor's power is quickly reversed and thus the motor will stop abruptly.
```sig
powerfunctions.brake(PowerFunctionsMotor.Red1)
```
### Parameters
- `motor` - the motor
## powerfunctions.float
Floats a motor to stop. The motor's power is switched off and thus the motor will roll to a stop.
```sig
powerfunctions.float(PowerFunctionsMotor.Red1)
```
### Parameters
- `motor` - the motor
## powerfunctions.setMotorDirection
Configures a motor direction.
```sig
powerfunctions.setMotorDirection(PowerFunctionsMotor.Red1, PowerFunctionsDirection.Right)
```
### Parameters
- `motor` - the motor
- `direction` - the direction of the motor
## MakeCode Example
```blocks
basic.showIcon(IconNames.Heart);
powerfunctions.connectIrLed(AnalogPin.P1);
powerfunctions.setMotorDirection(
PowerFunctionsMotor.Blue1,
PowerFunctionsDirection.Backward
);
input.onButtonPressed(Button.A, () => {
powerfunctions.setSpeed(PowerFunctionsMotor.Blue1, 3);
});
input.onButtonPressed(Button.B, () => {
powerfunctions.float(PowerFunctionsMotor.Blue1);
});
basic.forever(() => {
led.plotBarGraph(input.lightLevel(), 255);
if (input.lightLevel() > 200) {
powerfunctions.float(PowerFunctionsMotor.Blue1);
basic.pause(5000);
powerfunctions.setSpeed(PowerFunctionsMotor.Blue1, 2);
basic.pause(3000);
}
});
```
