Build a Bluetooth Controlled LED Strip

Introduction

Controlling an LED strip with Bluetooth is a fun and colorful project perfect for beginners wanting to add dynamic lighting effects. It teaches you how to work with LED strips, power management, and Bluetooth communication. Using BluetooIno simplifies sending commands from your phone, letting you customize colors and patterns easily without complex hardware.

How it works

In this project, BluetooIno connects your phone to the Arduino through the HC-05 Bluetooth module. You use the Buttons or Terminal Controller to send commands like color names or codes. The Arduino receives these commands over serial Bluetooth and adjusts the LED strip accordingly, controlling brightness and color channels via PWM signals. For example, sending “BLUE” lights the strip blue by activating the relevant LEDs.

Wiring the project

1.Connect the HC-05 module’s TX pin to Arduino RX (pin 0) and RX pin to Arduino TX (pin 1).

2.Connect HC-05 VCC and GND to Arduino 5V and GND.

3.Connect the LED strip’s data input to a PWM-capable Arduino pin (e.g., pin 6).

4.Connect the LED strip’s power line to an appropriate power source (usually 5V).

5.Ensure the LED strip’s ground and Arduino ground are connected.

6.Use a suitable power supply capable of delivering enough current for your LED strip length.

Upload Arduino code that listens for Bluetooth commands and controls the LED strip colors accordingly.

Conclusion

This Bluetooth-controlled LED strip project offers an exciting way to combine Arduino, wireless control, and colorful lighting effects. BluetooIno makes it simple to send commands from your phone, enabling you to create personalized light shows and ambiance with ease.
