Code Examples

### Example 1: Temperature and Humidity Monitoring

In this example, we will use the DHT11 temperature and humidity sensor to monitor environmental conditions and display the readings on the Micro:Bit's LED display.

Code:
```python
from microbit import 
import ustruct

while True:
    # Read temperature and humidity data from DHT11 sensor
    temp_humd = i2c.read(0x27, 5)
    temp = ustruct.unpack('H', temp_humd[0:2])[0]
    humd = ustruct.unpack('H', temp_humd[2:4])[0]

# Display temperature and humidity readings on Micro:Bit's LED display
    display.scroll("Temp: " + str(temp) + "C, Humd: " + str(humd) + "%")

# Wait for 1 second before taking the next reading
    sleep(1000)
```
### Example 2: Motion-Activated LED Lighting

In this example, we will use the PIR motion sensor to detect motion and trigger the 3-Color LED module to turn on when motion is detected.

Code:
```python
from microbit import

while True:
    # Read PIR motion sensor data
    pir_data = pin0.read_digital()

# If motion is detected, turn on the 3-Color LED module
    if pir_data == 1:
        pin1.write_digital(1)  # Turn on the LED module
        sleep(500)  # Keep the LED on for 500ms
    else:
        pin1.write_digital(0)  # Turn off the LED module
```
### Example 3: Sound-Activated Buzzer

In this example, we will use the sound sensor to detect loud noises and trigger the buzzer module to emit a warning sound.

Code:
```python
from microbit import

while True:
    # Read sound sensor data
    sound_data = pin2.read_analog()

# If the sound level is above a certain threshold, trigger the buzzer
    if sound_data > 500:
        pin3.write_digital(1)  # Turn on the buzzer module
        sleep(200)  # Keep the buzzer on for 200ms
    else:
        pin3.write_digital(0)  # Turn off the buzzer module
```
Note: In these examples, we assume that the Micro:Bit board is connected to the Smart Home Kit's sensors and modules according to the manufacturer's instructions. Additionally, the code examples provided are for illustration purposes only and may require modifications to suit specific use cases.
