Horten Fyr has 16 windows with  3008 RGB LEDs, which are individually controllable.

Under the pier there is a ultrasonic distance sensor (HRXL-MaxSonar-WR) – it is used to measure tides and wave-heights.

To control this we are using a  Teensy 3.2 w/OctoWS2811 ledcontroller and a  RaspberryPi 3.

The RaspberryPi’en is connected to the net to share its information with this page.
