Electric diagram

The electric diagram is a bit adapted to my preferences. I opted out for USB power (phone charger or power bank) instead of batteries, thru a diode to 5V pin. This prevents the servomotors to be powered when the board is plugged in to computer USB for programming, because the current draw would be too high.

Useless Box Arduino Nano

Arduino
Works with UNO too, no changes.
Just select the appropriate board from the Arduino editor at upload.
Is the old code you can find easily, but with some minor improvements that worked for me. Thanks a lot to the one who wrote it, this guy really knows FUN.
