Help controlling LED lights with 4 Channel Robodyn Light Dimmer

When I control the power of one light it works fine, but when I use two they flicker. I'm not very good at coding, so I was hoping someone could help. I tried making more of the class that controls the brightness, but it doesn't work.

This is the light dimmer:

My code:

  • The following sketch is meant to define the dimming value through the serial port of the controller,
  • using USE_SERIAL.begin
  • void printSpace() function is used for adding of space after functional data
  • void loop() serial port evaluator, used to register and define values in dimmer.setPower(outVal);

Here is the library: GitHub - RobotDynOfficial/RBDDimmer: The following library is used for work with dimmer, it gives ability to control large ammoun of dimmer. This lib uses with Leonardo, Mega, UNO, ESP8266, ESP32, Arduino M0, Arduino Zero, Arduino Due, STM32.

Please post the code correctly… CODE TAGS

At first glance, I’d guess your lights are flickering because you keep,re-setting them repeatedly in loop… Why?

but when I do a single one it doesn't flicker
