led

[gmazza]

Hello to all,
I would like to ask you to solve a problem.
In my code I have an LED that turns red or green depending on whether the information is correct or wrong. I want that when the LED turns red stays red forever (like to report a problem) although subsequent iterations do not give problems (and the LED would return to green).
How can I do?
Thanks

Shift Registers may solve your problem.

Hello.
I have tried using the Shift Register but I can not get the desired result.
Can you tell me how to wire the shift register to the LED "Error"?
Thanks

I enclose a picture of the piece of my code

Just add an OR into it.

I'm sorry I did not understand.
Where to add an OR? And what should I wire it?

[Dennis_Knutson]

Insert it into the feedback loop! One input goes to the write that is setting the condition and the other input goes to the shift register on the left side. The output goes to your Boolean indicator. Understand how that wil latch the output of the OR to true?

p.s. Don't forget to initialize the shift register to false.
