<html><body>IR Remote Controlled RGB LED Ring with Arduino NanoThis project turns an RGB LED ring into a smart remote-controlled light using an Arduino Nano and a standard IR remote. You can change colors, brightness, and activate different lighting effects like rainbow, breathing, and wave modes — all from a simple IR remote.Project OverviewThe Arduino Nano receives commands from an infrared remote through an IR receiver connected to the Nano’s sensor shield. Based on the button you press, the Arduino controls an 18-pixel NeoPixel (WS2812) LED ring, changing its color, brightness, or switching between effects.This is a great beginner-to-intermediate project for learning about:IR remote communicationControlling WS2812/NeoPixel LEDsWriting modular Arduino codeCreating smooth color animationsHow It WorksThe IR receiver connected to the Arduino Nano captures signals from your remote control.The Arduino decodes the signal and identifies which button was pressed.Depending on the code received, it adjusts the LED ring:Changes brightnessSwitches colorActivates a special lighting modeThe Adafruit NeoPixel library sends the color data to the LED ring to update the display.Circuit Connections (Using Arduino Nano + Sensor Shield)IR receiver OUT → D2NeoPixel ring DIN → D35V → 5V on both IR receiver and LED ringGND → Common ground for all componentsSoftware SetupOpen Arduino IDE.Go to: Sketch → Include Library → Manage Libraries.Install:The IR Remote library in the file section“Adafruit NeoPixel” by AdafruitCopy and upload the provided sketch to your Arduino Nano.If you are using a different IR remote, you can find your remote codes by printing them in the Serial Monitor:Serial.println(IrReceiver.decodedIRData.decodedRawData, HEX);Then replace the codes in the switch statement with your own.Remote FunctionsUp Arrow – Increase brightnessDown Arrow – Decrease brightness0 – Turn off all LEDs1 – Rainbow effect2 – Breathing effect3 – Wave effect4 – Red color5 – Blue color6 – Green color7 – Yellow color8 – Magenta color9 – Cyan colorOK – White (lamp mode)· Random colorLighting EffectsRainbow Effect – Smoothly cycles through all colors of the rainbow.Breathing Effect – LEDs fade in and out while changing hues.Wave Effect – A moving wave of brightness travels across the ring using the last solid color. The wave automatically reverses direction when it reaches the end.Power NotesThe LED ring can draw a lot of current at full brightness.For 18 WS2812 LEDs, it can use up to about 1 amp when showing full white.If possible, power the LED ring with an external 5V 2A power supply connected to the sensor shield’s 5V and GND pins.How the Code WorksThe IRremote library decodes signals from the remote and stores them in decodedRawData.The switch statement checks which code was received and performs an action.currentMode controls which animation is running:0 = solid color1 = rainbow effect2 = breathing effect3 = wave effectThe loop continuously listens for new commands and updates the LEDs.Ideas for ImprovementSave last color or mode in EEPROM so it remembers after power off.Add smooth brightness fading transitions.Add more effects like color wipe or sparkle.Use multiple LED rings or strips for larger displays.ConclusionThis IR remote-controlled RGB LED ring is an eye-catching and functional lighting project using an Arduino Nano and a sensor shield. It’s simple to build, fun to use, and easy to expand with new effects or hardware. Whether used as ambient lighting, decoration, or a small lamp, it’s a great way to explore Arduino-based RGB control.</body></html>
