Im pretty new in Android studio and need to make a Slider to view data recieved by an arduino via Wi-Fi (Temperature and Light).
What I want is to have a SemicircularSlider.kt composable that recieves de values of the arduino and displays them in a range which I will set on the Kotlin file.
Then With the Kotlin file I want to add them to my layout in my XML file like it’s another View, Or just a Widget and change the values (Like color and range of the slider) through XML.

As I’m new with Composable and Android Studio I tried making the Composable with ChatGPT and gave me This Code

@Composable
fun SemiCircularSlider(
    modifier: Modifier = Modifier,
    value: Float,
    onValueChange: (Float) -> Unit,
    colorStart: Color,
    colorEnd: Color
) {
    var angle by remember { mutableStateOf(0f) }

    Canvas(modifier = modifier
        .fillMaxSize()
        .padding(16.dp)
        .pointerInput(Unit) {
            detectDragGestures { change, _ ->
                val position = change.position
                val center = Offset((size.width / 2).toFloat(), (size.height / 2).toFloat())
                angle = ((atan2(position.y - center.y, position.x - center.x) * 180 / PI).toFloat() + 180) % 180
                onValueChange(angle)
            }
        }
    ) {
        val radius = size.minDimension / 2
        val arcRect = Rect(Offset(size.width / 2 - radius, size.height / 2 - radius), Size(radius * 2, radius * 2))

        drawArc(
            color = colorStart,
            startAngle = 180f,
            sweepAngle = angle,
            useCenter = false,
            style = Stroke(width = 20f),
            topLeft = arcRect.topLeft,
            size = arcRect.size
        )

        val thumbX = center.x + cos((angle - 180) * PI / 180).toFloat() * radius
        val thumbY = center.y + sin((angle - 180) * PI / 180).toFloat() * radius

        drawCircle(
            color = colorEnd,
            radius = 20f,
            center = Offset(thumbX, thumbY)
        )
    }
}

@Composable
fun MainControlScreen() {
    var temperature by remember { mutableStateOf(0f) }
    var light by remember { mutableStateOf(0f) }

    MaterialTheme {
        Column {
            Text("Temperature: ${temperature.toInt()}")
            SemiCircularSlider(
                value = temperature,
                onValueChange = { temperature = it },
                colorStart = Color(0xFFFF5722),
                colorEnd = Color(0xFFFFC107)
            )
            Spacer(modifier = Modifier.height(32.dp))
            Text("Light: ${light.toInt()}")
            SemiCircularSlider(
                value = light,
                onValueChange = { light = it },
                colorStart = Color(0xFF03A9F4),
                colorEnd = Color(0xFF4CAF50)
            )
        }
    }
}

I didn’t really asked for all about the arduino connection because I can’t even show a semicircular slider on the screen
This solution dropped me the error "org.jetbrains.kotlin.backend.common.BackendException: Backend Internal error: Exception during IR lowering"

Feel free to ask any questions if needed or ask for more code. And sorry if my English is a bit off.
