Code Examples

Turning Servo

stemhubCity.servo(90, AnalogPin.P0)

Read sound sensor

let sound = stemhubCity.read_sound_sensor(AnalogPin.P0)

Control traffic light

let trafficLight = stemhubCity.traffic_light_setting(DigitalPin.P0, DigitalPin.P1, DigitalPin.P2)
basic.forever(function () {
    trafficLight.traffic_light_control(true, false, false)
    basic.pause(1000)
    trafficLight.traffic_light_control(false, true, false)
    basic.pause(1000)
    trafficLight.traffic_light_control(false, false, true)
    basic.pause(1000)
})

Control color led

let colorLED = stemhubCity.color_led_setting(AnalogPin.P0, AnalogPin.P1, AnalogPin.P2)
colorLED.color_led_control(1023, 500, 0)

Turn on white LED when motion detected

basic.forever(function () {
    if (stemhubCity.read_motion_sensor(AnalogPin.P0)) {
        stemhubCity.turn_white_led(1023, AnalogPin.P2)
        basic.pause(1000)
        stemhubCity.turn_white_led(0, AnalogPin.P2)
    }
})

Read Ultrasonic

let distance = stemhubCity.read_distance_sensor(stemhubCity.DistanceUnit.Centimeters, DigitalPin.P15, DigitalPin.P16)

Turn on fan if keypad key “1” is pressed

basic.forever(function () {
    if (stemhubCity.readKeyPad(DigitalPin.P0, DigitalPin.P1) == "1") {
        stemhubCity.FanControl(stemhubCity.FanState.On, DigitalPin.P14, DigitalPin.P15)
    }
})

Use OLED screen to display string

stemhubCity.OLED.init(128, 64)
basic.forever(function () {
    stemhubCity.OLED.writeStringNewLine("hi")
    basic.pause(500)
    stemhubCity.OLED.writeStringNewLine(":)")
    basic.pause(500)
    stemhubCity.OLED.clear()
})
