Demonstrates a simple counter with theme toggling using IoT-C variables and microcontroller control (e.g., LED indicator).

VAR temp;

    temp = TEMP_SENSOR();
    PRINT("Current Temp: ", temp);
    IF temp > 30 THEN PRINT("Warning: High Temperature!");
}

// Simulate readings
readTemp();
readTemp();

Reads temperature from a sensor and prints alerts.

VAR presses = 0;
PROC buttonPressed() {
    presses = presses + 1;
    PRINT("Button pressed: ", presses);
}

// Simulate button presses
buttonPressed();
buttonPressed();
buttonPressed();

Counts the number of button presses and prints the count.

    FOR i = 1 TO times DO
        LED_ON();
        DELAY(500);
        LED_OFF();
        DELAY(500);
    END;

    lightLevel = LIGHT_SENSOR();
    IF lightLevel < 50 THEN LED_ON(); ELSE LED_OFF();
    PRINT("Light Level: ", lightLevel);
}

PROC checkDistance() {
    distance = DISTANCE_SENSOR();
    IF distance < 10 THEN PRINT("Alert: Object too close!");
    PRINT("Distance: ", distance);
}

checkDistance();
checkDistance();

Reads a distance sensor and prints alerts if object is too close.

VAR humidity;
PROC monitorHumidity() {
    humidity = HUMIDITY_SENSOR();
    IF humidity < 30 THEN PRINT("Too Dry!");
    IF humidity > 70 THEN PRINT("Too Humid!");
    PRINT("Humidity: ", humidity);
}

Monitors humidity and prints if it is too high or low.

VAR temp, light;
PROC dashboard() {
    temp = TEMP_SENSOR();
    light = LIGHT_SENSOR();
    IF temp > 30 OR light < 50 THEN LED_ON(); ELSE LED_OFF();
