Do you think you can detect the light in just 50 milliseconds? Try 1000 milliseconds.

Common Anode.

What is the (presumably) common pin on the LED connected to?

The project looks OK except as @Paul_KD7HB pointed out we do not believe your eyes are fast enough. Adjust the time as suggested and it should work.

Your 5V pin goes nowhere.

Not if @van_der_decken and @sonofcy are correct!

Hi,
Code works with 100ms delay, but as previously said, is the LED common anode or cathode.
From what I have here it is common ANODE.
So needs a simple rewire.

Tom.. :smiley: :+1: :coffee: :australia:
