![]() ![]() The result is a mix of many different colors because each color has its own intensity. They will then use PWM (Pulse Width Modulation) to change the intensity of each LED according to a specific algorithm. These are small devices that you can connect directly to your power source, or in the case of a battery-powered one, the battery power supply. The simplest way to make your led lights rainbow is by using a color changer. 8 Simple Ways to Make Your Led Lights Rainbow 1) Using Color Changer Once the rainbow effect is set, enjoy the vibrant and dynamic atmosphere created by your LED lights. Adjust the speed of the color transitions to achieve the desired effect. If a preset rainbow effect is not available, create your own by programming a custom color sequence that transitions smoothly between the colors of the rainbow (red, orange, yellow, green, blue, indigo, and violet). Many controllers and apps include pre-programmed color sequences or effects, and you may find a rainbow effect among these options. Once the lights are installed, use the provided controller or a compatible smartphone app to access the color and effect settings. To make your LED lights display a rainbow effect, first install the RGB LED lights or light strips in the desired location, following the manufacturer’s instructions for mounting and connecting them to the power supply. ![]() Before starting, ensure that your LED lights are compatible with this functionality and gather any necessary materials and tools, such as a power supply, connectors, and mounting hardware. These lights usually come with a controller or an app to customize the colors and effects. To achieve this, you will need RGB (red, green, blue) LED lights or LED light strips, which are capable of producing a wide range of colors by combining different intensities of red, green, and blue light. Summary: Creating a rainbow effect with your LED lights can add a fun and colorful ambiance to your space. The process is simple and only takes a few steps. In this blog post, we will be explaining how to make your LED lights rainbow. However, if you are looking into the world of led lights, one thing that immediately strikes you is how these lights can be easily customized and change from one color to another, just like a rainbow! They represent the diversity in our world and how we can all live together peacefully. With that done, the next stage is to wire the setup function which runs once at the start of the program execution.The colors of the rainbow are a symbol of diversity. The first task is to include the required WiFiNINA header file and we do that using the following line of code: #include This kind of program is equivalent to the blinking the green LED on the Raspberry Pi Pico which was discussed in this tutorial. The basic blink program demonstrates simply how to switch the colour of the LED to flash in a binary fashion. It may take a couple of minutes to download and install this library but once it is completed you can close that window and you are ready to start writing code! Basic Blink Program To install these libraries in the Arduino IDE go to Sketch > Include Libraries > Manage Libraries then in the window that opens search for, and install, the following library: UBlox NINA Chip on the Arduino Nano RP2040 Connect Required Libraries ![]() ![]() Fortunately, this is quite easy and a library already exists for us to use this. So in order to use the RGB LED, we are going to have to go through this WiFi module. If we have a look at where these labels are actually connected too, we can see they are connected to pins 16 to 18 on the UBlox NINA Module. We can see that the RGB LED is simply three separate LEDs that are all connected to the same power source on their anode, or positive side, and their negative sides are connected to a corresponding LED label LED B, G and R signifying their colours: Common Anode RGB LED on the Arduino Nano RP2040 Connect The Arduino Nano RP2040 Connect has an onboard RGB LED which is what is known as a ‘common anode’ LED. You can find the final source code and the video tutorial is available here (or embedded at the bottom of this page). Create a rainbow effect to fade between colours.We will walk you through how to create three different sketches using the Arduino IDE which will: This tutorial will teach you how to use the RGB LED on the Arduino Nano RP2040 Connect. ![]()
