Example Code for UNIHIKER-LED Control

Hardware Preparation

• 1 x UNIHIKER
• 1 x photo interrupter
• 1 x Two-end PH2.0-3P White Silicone Twisted Wire

Software Preparation

• MindPlus

Wiring Diagram

Connect the photo interrupter to pin P23 on the UNIHIKER, and connect the LED light to pin P24.

Sample Code

from pinpong.extension.unihiker import *
from pinpong.board import Board, Pin

# Initialize the board
Board().begin()

# Set up the input pin for the photo interrupter
p_p23_in = Pin(Pin.P23, Pin.IN)

# Main loop
while True:
    # Check if the photo interrupter is blocked
    if p_p23_in.read_digital():
        # If blocked, turn on the LED
        p_p24_out = Pin(Pin.P24, Pin.OUT)
        p_p24_out.write_digital(1)  # Turn on the LED
    else:
        # If not blocked, turn off the LED
        p_p24_out = Pin(Pin.P24, Pin.OUT)
        p_p24_out.write_digital(0)  # Turn off the LED

Result

After the program runs successfully, cover the photo interrupter with an object, and the LED light will turn on. When the object is removed, the LED light will turn off.
