The electronic board
To provide animation to the model I designed an electronic circuit to control the lighting (above the captain, also green and red navigation lights), the scooper-conveyor, the paddle wheels and also to provide sound effects (sound of splashing water, boat horn, machinery noise).
The "brain" of the control circuit is an Arduino Nano; for the sound effects I used a miniature MP3 player with a memory card connected to a small speaker. I assembled the circuit on a small circuit board.
