Unfortunately @Shadeyman hasn’t visited the forum for 5 months, and it’s almost a year and a half since he last posted here.
As the project that you’re trying to replicate was simply a toy for his kids to play with and was built two years ago, I doubt very much if he still has the details available.
You have lots of clues available to you in the photos he posted, plus a link to the Adafruit site with wiring diagrams for the Arduino.
If you aren’t interested in doing your own experimentation and improving your C++ coding skills in the process then you aren’t going to get very far with MCUs or Blynk.
Your attitude towards @distans certainly won’t get you very far, except maybe suspended or banned from the forum.
The forum rules are quite clear and I’m happy to enforce them when necessary…
Pete.
