I was practicing making a schematic from the project I found on google. I made the schematic in kicad the same as given in this photo but when I am running ERC I am getting errors on several pins of ic ( pin no. 4,6,7,10,13,17,18,19,20)…should I use ‘no connection’ on these pins?
As you used there some labels at these pins so the pins are intended to be connected with something so using ‘no connection’ does not make sense. You should rather try to find why KiCad doesn’t see that connections.

You have used net labels that only apply to the sheet that they are on. I don’t see the same labels elsewhere on this page, so they are not connected

With those photos of your monitor (damn, what an idea?!!) you’re not making it easier for others to help you. Worst case do a screenshot (mind the orientation) and dropi it here. Will be much better than the photos.
Regarding the connections, many seem to have a generic label (kind of PA3 - means port A, pin3). Look like they’re not used, so use the “Not connected” cross.
Better yet, show your kicad schematic (screen) after ERC run.

From my point of view if there is any label at wire going out of IC pin then these pin is intended to be connected with something. If I don’t plan to connect it with anything I just don’t add any piece of wire to it and no label it. As you see no wire at pin then it is obvious that it is unconnected. I don’t need extra marking that pin is unconnected. I don’t care what ERC thinks about it - I just don’t run ERC.

Yes of course posting the original .;pdf is good.
Other options are (in windows) snipping tool (now “snip and sketch”) or ALT-PrtScr (printscreen).
If you are posting a non-.pdf image, drawing images are more efficiently and clearly compressed with .png format than .jpg. (Leave .jpg for family/landscape photos etc.) And even further; IRFANVIEW can reduce the number of colors to minimize the file size. (How many colors does a schematic diagram need?)

Thanks for the suggestions. Next i will use snipping tool:slightly_smiling_face:
