This is a description of an adventure: building a controller that could simulate sunrise and sunset.
Disappointed due to the imprecision of the Chinese timmers and the difficulty in setting the time, I decided to devote myself to building a digital controller.
It all started in a shoe box with one Arduino, an RTC and a 3mm LED's.
Control any LED driver that accepts input of 5V or 10V PWM, Meanwell or Buckpuck, and I can put several drivers in each channel.
- Four independently controlled channels.
- Possibility to set the time (on / off), maximum intensity and fade time for each channel.
- Real-time clock.
- LCD screen showing the hours, minutes, seconds, and intensity level of each channel.
