To run Multicolor LED Strips, you need a controller to switch between colors.
Generally, RGB indicators with positive "+", red "R", green "G", and blue "B" are connected to the controller according to the corresponding identifier.
Connect the other end of the controller to a power supply. When powered up, you quickly press the 'O' button on the remote pad three times to pair the controller with the remote, and the Multicolor LED Strips work properly.
