# What is a hardwareMap?

A hardwareMap is a class in the FTC SDK that, using its get method, takes a class for a specific device and its name in the configuration file you made using your REV Driver Hub. It then returns an object for the device you inputted and allows for you to control it in code.

    private val imu: Gyroscope
    private val motorTest: DcMotor
    private val digitalTouch: DigitalChannel
    private val sensorColorRange: DistanceSensor
    private val servoTest: Servo

    init {
        imu = hardwareMap.get(Gyroscope::class.java, "imu")
        motorTest = hardwareMap.get(DcMotor::class.java, "motorTest")
        digitalTouch = hardwareMap.get(DigitalChannel::class.java, "digitalTouch")
        sensorColorRange = hardwareMap.get(DistanceSensor::class.java, "sensorColorRange")
        servoTest = hardwareMap.get(Servo::class.java, "servoTest")

# What would you use it for?

The hardwareMap class is used to initializing every component of your robot into your code so you can control each of them. For example, for a DcMotor assigned to the variable frontLeftMotor, you would turn it on full power using frontLeftMotor.power = 1.0. Note how power for motors is stored as a Double. Overall, the hardwareMap class is vital to programming, and it will be used extensively throughout your entire FTC programming career.
