![]() ![]() With that done, the next stage is to wire the setup function which runs once at the start of the program execution. 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. include Include Libraries > Manage Libraries then in the window that opens search for, and install, the following library: Arduino has changed the world of electronics from the ground up. 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. Maby Ashish Adhikari Fork Project How to fade a LED with or without an Arduino automatically or manually using a potentiometer. 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 âcommon anodeâ 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: Because your for loop will be too quick for you to notice the fading. Then, each time through loop (), it checks if a long enough interval has passed. ![]() It keeps track of the last time the Arduino turned the LED on or off. This tutorial will teach you how to use the RGB LED on the Arduino Nano RP2040 Connect. I think your code is not so bad, you just need delays. This sketch demonstrates how to blink the LED without using delay (). ![]()
