How to make Arduino Bluetooth RGB Mood Light Lamp

Arduino hobbyist / By / Leave a Comment

In this project I’ll show you how to build a simple and complex Arduino Bluetooth mood light projects you can control with your smartphone.

This is made simple with this smart application Remote XY.

It’s a website and phone app that can help you create wireless Arduino projects easily.

You can make your mood light, RC car, Quadcopter, Home Automation or any other projectusing this basic information to connect Arduino to your smartphone via Bluetooth connection.

All the projects can be made simple thanks to this genius application.

Hardware required:

Arduino UNO Board

Amazon US, Amazon UK , Amazon DE, Amazon FR , Amazon ES, Amazon IT ,

eBay, Banggood , Aliexpress

HC-06 Bluetooh Module

Amazon US, Amazon UK , Amazon DE, Amazon FR , Amazon ES, Amazon IT ,
eBay, Banggood , Aliexpress

Red, Green and Blue LEDs

I connected the negative (shorter) leg of the three LEDs together for easy use.

Jumper wires

Connection Ciruit

The connection is very simple.

You connect the Arduino Board to the Bluetooth Module via the hardware serial port(Pin #0 and Pin #1).

Connect LEDs as follows

Pin # 9 Red LED +ve terminal (Longer Leg)

Pin # 10 Green LED +ve terminal (Longer Leg)

Pin # 11 Blue LED +ve terminal (Longer Leg)

Editor

Open Remote XY Editor at RemoteXY.com and place controls. RGB control and Toggle switch. Here is where you can design the Smartphone interface.

You can configure controls appearance here.

You need to download the generated code from the editor. You also need to include the Remote XY library from the same page.

Then you need to edit the code in Arduino IDE.

That’s because the generated code only configures the controls. Then you need to code the actions between Arduino and those controls.

Download Remote XY App from Google Play or Apple Store.

Open it and connect to your device.

You can see the interface loads on your smartphone.

This is how the interface looks on the Smartphone.

Note:

You don’t need to be connected to the internet for using this interface between the phone and Bluetooth Module.

Run the application and power up the device.

Try the different modes of operation.

In the RGB mode, you can control the output color using the RGB circular control.

In the MOOD mode, the light fades in and fades out automatically.

In this project, I made a quick light diffuser using a piece of white paper.

Thank you for reading.
