**Example Code (MicroPython)**

 ```
# Example for detecting a line using the Makerverse IR Line Sensor

from machine import ADC
from utime import sleep

line_sensor = ADC(28) # Use any of the 3 ADC channels on the Pico

line_threshold = 45000 # Set this according to your ambient conditions

while True:
    line_sensor_value = line_sensor.read_u16() # Get a reading from the ADC
    # print(line_sensor_value) # Uncomment this line to find the threshold
    
    if line_sensor_value > line_threshold: # 
        print('Line detected!')
        # TODO: Anything! Put your code here!
        
    sleep(0.2)
```
