UNCONNECTED PIN

 

Here’s an interesting one – Unconnected pin LED2 C. Now, if you wired up your schematic correctly in SCHEMATIC PART then you won’t have this error, but apparently we messed up!

If we zoom in to the bottom pin of LED2 then we can find the problem. See how the green line is darker next to the bottom of the pin in the image below? That means it’s not connected properly to the LED2 pin and is actually overlapping it.

Check out the overlapping pin that we missed, shown in dark green. We can fix this by deleting the net and adding it again.

This is a simple fix, we just need to delete the existing net with the Delete icon, then rewire it with the Net icon. And with a quick closing and reopening of our ERC Errors Dialog, the problem is solved.
