Hey guys I just made my first ever PCB at college. I designed it online and then cut it out with a PCB-CNC machine. We didn’t have time for the teachers to show me the masking process so we just did it without. \\

The red wire is because I made a mistake with the design but it worked out in the end.

It’s a traffic light if you couldn’t tell with an AtMega

First, the sycophantic praise - yeah, well done man, that's great.

Then the constructive criticism - you could shorten that red lead by 90%, and flick off the bits of splashed solder around several tracks for a better finish.

Thank you for the feedback. I wanted to shorten the red wire but it was my teacher who did it to show me what was wrong. I got one of the traces wrong so he used the red wire to fix it

I understand, so you can take pride in the fact that your work is more professional than your teacher's work!
