Is there a ready-made Arduino sketch for flashing a Christmas tree garland using a relay?

Question

Arduino

There is a Christmas tree garland, it burns from 220v, it does not blink and does not overflow, I connected it to the arduino through a relay, now it just blinks every second.
Maybe someone has a ready-made sketch with interesting flashing lights for the relay? I do not want to waste time on such nonsense and write myself.

Answer 1

I'm afraid others will not be very pleased to listen to the click of the relay. In addition to flashing on the relay, nothing can be realized.

Answer 2

Well, it's better to put a powerful transistor instead of a relay, it will be quieter and faster.
A sketch once saw a similar one for rgb LEDs. But smooth decay with a relay will not work; for this, PWM is used, and the relay operates too slowly for PWM.

Answer 3

The maximum that is possible is to flash the entire line at the same time according to some program (well, like Morse code :) every channel. If you get confused and screw a microphone to the arduino (or send an audio signal like music from any source), then a light and music option will become available, there are sketches on the Internet. Well, as a climax - throw out this garland and connect a line of addressable RGB LEDs like WS2811 to the arduino and finally make sure that other Christmas tree garlands fade in comparison.
