First of all, I would like to congratulate you for participating as the first user in our community, and secondly, I would like to congratulate you for joining my friend's educational lesson competition, and you showed it very well, and you were able to do the soldering very beautifully. However, I found a little problem in one task, which is that the wires were not soldered in a nice finishing way. I hope it will be better in the future.
