The lighthouse is powered by a 12v wall power. Inside is Arduino nano. All the LEDs are pwm controlled. The flash is programmable. The lighthouse also has indoor lighting (illuminated windows). All LEDs are 5 mm. parts screwed together. The cap with the hot glue attached. The lighthouse is about 40cm high.

The model may not be perfect, but if it could inspire you.

There is still much to be done on this model. Version 2 may come later. Or not.
