Hello to all.
How do light up an led shutting circuit from uC at ground?
When the button is pressed to be ignited led.
Thank you in advance!

Hello,

Here is a quick program that will do what you want. I have basically done the same program twice, the first loop I used the switch and LED components via component macros and in the second loop I used I/O icons.

Good evening Benj,
Thank you very, very much, works great, thank you once again.
