The main steps of making rainbow lights are as follows.

1. Select the RGB LED strip. This strip has red, green and blue LEDs, which can be controlled individually to produce a variety of colors, including rainbow effects. A common option is 5050 RGB LED strip.

2. Prepare the LED strip controller. The controller can individually control the brightness of the red, green and blue LED channels, thus changing the color and effect. Common types of controllers are remote control, wall panel controller or Bluetooth/Wi-Fi smartphone app.

3. Connect the RGB LED lighting strip to the controller and 12V DC power supply. There are 4 wires on the strip – positive, negative, red, green and blue. Connect them to the matching inputs of the controller.

4.Turn on the highest brightness of the red LED channel. Slowly turn down the red brightness and increase the green brightness. This will make the color change from red to orange, then yellow.

5.Continue to increase the green brightness, while turning down the red brightness, until the green reaches its maximum brightness. This will show green on your LED strip.
6. Now turn down the green brightness while increasing the blue brightness. This will make the color change from green to cyan, and then to blue-green.
7. Turn the blue to the highest brightness, then start reducing the blue brightness while increasing the red brightness again. This completes a rainbow cycle, the color from blue back to red.
8. Adjust the relative brightness of red, green and blue as needed to make the rainbow colors more or less intense. Evenly balanced across channels can produce a vivid rainbow of colors, adjusting down the brightness of one or more channels will make the colors lighter and lighter.
9, the controller is set to “rainbow color” or “color change cycle” mode. Many controllers have built-in automatic cycling rainbow color change effect. Simply adjust the cycle speed as needed. 10.Consider adding a light diffuser to the LED strip to enhance the rainbow effect. Diffusers help mix and diffuse individual reds, greens and blues to create a smoother spectrum of hues.

This is a simple example of using Arduino to control an RGB LED strip lights to achieve a rainbow light effect.

c
int redPin = 11; //pin for red LED
int greenPin = 10;//pin for green LED
int bluePin = 9; //pin for blue LED

void setup() {
pinMode(redPin, OUTPUT);
pinMode(greenPin, OUTPUT);
pinMode(bluePin, OUTPUT);
}

void loop() {
//red
analogWrite(redPin, 255);
analogWrite(greenPin, 0);
analogWrite(bluePin, 0);
delay(2000);

//orange
analogWrite(redPin, 255);
analogWrite(greenPin, 63);
analogWrite(bluePin, 0);
delay(2000);

//yellow
analogWrite(redPin, 255);
analogWrite(greenPin, 255);
analogWrite(bluePin, 0);
delay(2000);

//green
analogWrite(redPin, 0);
analogWrite(greenPin, 255);
analogWrite(bluePin, 0);
delay(2000);

//cyan
analogWrite(redPin, 0);
analogWrite(greenPin, 255);
analogWrite(bluePin, 63);
delay(2000);

//blue
analogWrite(redPin, 0);
analogWrite(greenPin, 0);
analogWrite(bluePin, 255);
delay(2000);

//indigo
analogWrite(redPin, 63);
analogWrite(greenPin, 0);
analogWrite(bluePin, 255);
delay(2000);

//violet
analogWrite(redPin, 255);
analogWrite(greenPin, 0);
analogWrite(bluePin, 255);
delay(2000);
}

This code will display red, orange, yellow, green, cyan, blue, indigo and violet colors sequentially on the RGB LED strip. By gradually changing the brightness ratio of the red, green and blue three channels, the effect of seven-color rainbow change is achieved.
You can modify the code according to your needs to achieve different rainbow effects.

The easiest way buy a led strip lighting

Yes, purchasing special rainbow light effect lamps is the simplest way to achieve this effect. Some options include:
1. Rainbow light strip – This is an RGB LED strip with built-in rainbow color changing effects that can be plugged in and used directly. Users only need to adjust the speed and brightness of the change. This is the simplest way to achieve a rainbow light effect.
2. Smart rainbow lamp – These lamps have built-in rainbow color changing effects and can be controlled by a mobile app or voice control device (such as Amazon Echo). Users can choose different rainbow color changing modes and speeds.
3. Rainbow floor lamp – This is a high quality rainbow lighting solution. The floor lamp is fashionably designed with a variety of built-in rainbow and color changing effects for users to choose from. It can be controlled by a remote control or smart device.
4. Rainbow chandelier – This chandelier uses a rainbow LED design with built-in color changing software to achieve delicate rainbow effects. Users can choose different rainbow color changing modes, speeds and colors through the remote control.
In addition to the above options, some companies also sell single color LED lights (red, yellow, green, blue, etc.) for users to assemble and control themselves to DIY their favorite rainbow effects. However, compared to dedicated rainbow lighting fixtures, DIY is more difficult and the effects achieved may not be ideal.

Debugging and testing

Debugging and testing is an important step in creating the rainbow light effect. You need to check the following points.
1. whether the LEDs all light up properly. If some of the LEDs can not light, you need to check the LED and its circuit connection is not a problem, and the necessary repair or replacement.
2, red, green, blue LED change effect is smooth. Need to see whether each color is uniform change, change time interval is similar. If a color change is not obvious or the time interval is different, usually indicates that the color channel control or circuit problems, you need to check the corresponding part and repair.
3. rainbow change effect is to meet expectations. The order of change is correct (red, orange, yellow, green, blue, indigo, purple), the color transition is smooth and natural. If the effect is not satisfactory, you need to re-check the program or settings, to make adjustments.
4. change the smoothness of the effect is in line with the requirements. If the change is too fast or too slow, you can adjust the time settings through the controller or program to change the speed of change, to achieve the desired effect.
5. whether the brightness settings are appropriate. The color is too dark or too light will affect the performance of the rainbow effect, you need to adjust the brightness to the best state through dimming and other means.
6. whether the color settings need to be adjusted. If some color performance is not ideal, you can try to adjust the color settings through the controller or reprogramming and other targeted, such as adjusting the brightness higher or lower, expand or shorten the lighting time.
At lastly, the purpose of debugging is to check whether all the hardware LED components and control circuits or procedures are working properly, and the problems exist to make the necessary corrections to achieve the desired rainbow change effect. Check several times, compare the expected effect, make repeated adjustments, and finally complete the debugging work.
