kotlin-firmata

⚠️ Work in progress, the library is not in a stable form yet!

This project's main focus is to make a multi-platform firmata with kotlin. This would open a new DIY world for developers who don't really want to dive into C, but also to create full support for some platforms like Android

How to use

1. Implement your version of connection.Connection by setting up your protocol. This could be USB, Wi-Fi, Bluetooth whatsoever
2. Create new Firmata object
3. Create the element you want to use from the firmata
4. Have fun, experiment create whatever you want!

Setup firmata

// Tell the firmata which connection protocol to use
val firmata = Firmata(connection)

Example Pwm Led

// Create a new led component on pin 11 (on arduino uno it's a PWM)
val led = firmata.PWMLed(11)
// Set a random value between 0 and 1, where 0 is off, and 1 is the maximum brightness
led.setBrightness(Math.random().toFloat())

Example Servo

// Create a new servo component on pin 6 (on arduino uno it's a PWM)
val servo = firmata.Servo(6)
// Tell the servo to go into a position between 0 and 1. See kotlin docs for further usage
servo.to(0.7F)

Example Motor with RadioGroup

// Create a new motor component with pins 2 and 3
val motor = firmata.Motor(2, 3)
// Set on radio group change
(root.findViewById(R.id.radioGroup) as RadioGroup).setOnCheckedChangeListener { radioGroup, _ ->
    // Just a when do! :D
    when (radioGroup.checkedRadioButtonId) {
        R.id.backwards -> motor.turnBackward()
        R.id.forwards -> motor.turnForward()
        R.id.stop -> motor.stop()
    }
}
