- 1. HAND GESTURE BASED RGB LED STRIP CONTROL USING ARDUINO
- 2. abstract: • We all have seen different kinds of mood lamps & RGB light, most of them have some buttons or a remote to interact with them, but we thought of making a Gesture Controlled RGB Desk Lights which can change its color only using a simple swipe gesture as a trigger. This is an interactive art project made using the Arduino Uno board & Gesture Sensor. • The remote control can be a stationed unit or a wireless remote. • The remote used for controlling appliances usually have keys or touch- based sensors. • In this project, a home automation system is designed which can be controlled by gestures.
- 3. introduction • What is Hand Gesture-Based LED Control? • A system that allows users to control LEDs using hand gestures. • Uses sensors to detect gestures and translate them into commands. • Why is it Important? • Provides a touchless and intuitive way to control devices. • Useful in smart homes, healthcare, and automation.

- 8. Working Principle • Step 1: Gesture sensor detects hand movements. • Step 2: Sensor sends data to the microcontroller. • Step 3: Microcontroller processes the data and identifies the gesture. • Step 4: Based on the gesture, the microcontroller sends signals to control the LEDs (e.g., turn on/off, change brightness, or color).
- 9. Gesture Recognition • Types of Gestures: • Swipe Left/Right • Swipe Up/Down • Circular Motion • How Gestures are Detected: • Infrared or motion sensors capture hand movements. • Algorithms process the data to identify specific gestures
- 10. Circuit Diagram • Include a clear and labeled circuit diagram showing: • Connections between the gesture sensor, microcontroller, and LEDs. • Power supply and resistors.
