Example Tutorial

1. Show the light sensor reading

The light sensor will return the percentage value of luminance in environment

Maxmium:100
Minmium:0

basic.showNumber(House.getLight(AnalogPin.P0))

2. Show the distance sensor reading

The Distance sensor will return the distance between sensor and object

Maxmium:4M
Minmium:3cm

basic.showNumber(House.read_distance_sensor(House.DistanceUnit.Centimeters, DigitalPin.P14, DigitalPin.P15))

3. Show the flame sensor detection result

The flame sensor will return the detection of fire result

Detected:TRUE
Not Detected:FALSE

if (House.getFlame(DigitalPin.P0)) {
	basic.showString("Detected!")
}

4. Get the motion sensor detection result

The motion sensor will return the motion changing at the front

Detected change:TRUE
Not Detected change:FALSE

if (House.read_motion_sensor(DigitalPin.P0)) {
	basic.showString("Detected!")
}

5. Action when the Button pressed

The function in the block will be execute after the button (connected to pin) pressed

House.Button(House.PressButtonList.b0, function () {
    basic.showString("Pressed!")
})

6. Read and get the value of temperature and humidity

The DHT11 sensor will return the temperature and humidity in environment, and save in the variable

Before showing or using the variable, need to be read the DHT11 sensor

For Temperature
Maxmium:50 Celsius degree
Minmium:0 Celsius degree

For Humidity
Maxmium:80%
Minmium:20%

House.readDHT11(DigitalPin.P0)
basic.showNumber(House.readTemperatureData(House.Temp_degree.degree_Celsius))
basic.showNumber(House.readHumidityData())

7. Get the IAQ Score

Base on the temperature and humidity, the IAQ score will repersent the comfortability of environment

Before geting the IAQ score, need to be read the DHT11 sensor

House.readDHT11(DigitalPin.P0)
basic.showNumber(House.getIAQ())

8. Turn on the Motor Fan

Input the value to let the motor fan work in different speed

Maxmium:1023
Minmium:0

input.onButtonPressed(Button.A, function () {
    House.TurnMotor(1023, AnalogPin.P1)
})

9. Control the 180 degree servo motor

Input the value to let the 180 degree servo motor move to specific position

Maxmium:180
Minmium:0

input.onButtonPressed(Button.A, function () {
    House.Turn180Servo(180, AnalogPin.P0)
})

10. Control the 360 degree servo motor

Choose the direction and speed to let the 360 degree servo motor to moving in specific way and speed

For direction
Maxmium:clockwise
Minmium:anti-clockwise

For Speed
Maxmium:Level 3
Minmium:Stop

input.onButtonPressed(Button.A, function () {
    House.Turn360Servo(House.ServoDirection.clockwise, House.ServoSpeed.level3, AnalogPin.P0)
})
