Hi, I about to start making projects with arduino but first I needed to learn soldering so I bought the velleman soldering kit.
the first project MK102 works fine.
Then the second project MK103 - I can’t get it to work, so I was wondering if it is simply because I have some joints overlapping each other? Also, 2 leds were missing in the kit so I have only 2 on the board - but would that cause any problems?
