Hi.
You’re right.
Thanks for letting me know.
I’ll fix the code.
Regards,
Sara

led_pin = 2
sensor_pin = 12

Further down the article in the explanation they are correct:

Pin numbers for LED and sensor

led_pin = 21
sensor_pin = 22

Hi Sara, sure! The “good ones” reached about 3-4 meters while the others went randomly between 2 and 5 centimeters.

Hi.
Thanks for your feedback.
Can you give me an idea of the maximum distance range?
Regards,
Sara

I had to order to a third store, and via Amazon to get some properly working units.
