Yes
Could you elaborate, please? Or attach a link to a project?
Thanks
The simplest way would be to use a Real Time Clock to maintain accurate timing and to switch a relay on/off at the appropriate times.
A (mechanical) timer switch would work perfectly for a job like this. Just plug in the LED string's power supply, set the clock, done.
