Lichtla is an Arduino nano powered home ambient lighting system I made to use as a night light for my children on the corridor that separates the three rooms. The lamp is consuming less than 3 Watts of power that allows it to be turned ON the entire night.
The lamp is basically composed by a 12V power supply, an Arduino nano, a 24 channel PWM LED driver from Adafruit and is connected to 8 RGB LED’s. The components are assembled within a standard casing found in an usual hardware store so that the lamp can be mounted directly on the ceiling and connected to the house electrical system.
The software is randomly and smoothly changing the color of the LED’s every some minutes to accommodate to ALL wishes I’ve got from my children in term of colors to be used.
