Introduction: Color Changing RGB Strip Using BLEduino

About: ElecFreaks is an open design house founded in March 2011. Our goal is to create rapid prototypes and give small-batch manufacture solution for makers and startups. With over 50% staff as engineers and expanded…

Smart RGB LED Strip is based on the development of our BLEduino, using the Bluetooth 4.0, and the sample code written by EF men, by mobile phone APP, to control the switch of RGB LED strip, and the RGB LED color changing. The main principle is that using BLEduino mega328P chip three PWM pins respectively to control the RGB LED strip of R G B three colors. When the phone APP and BLEduino bluetooth pairing connection succeed, phone APP can control mega328P chip three PWM pins output value, then control the the color of the RGB LED strip This project is very easy – making, as long as with three things of BLEduino, BLE mobile phone APP, RGB LED Strip, we can complete it, which enable more Arduino starters to participate in this project. What’s more, we can apply this project to finish a Christmas tree with smart RGB LED Strip.

Step 1: Hardware and Software

Hardware

  1. Android or Apple mobile phone with System 4.3 and Bluetooth 4.0

  2. USB Cable

  3. RGB LED Strip

  4. BLEduino Mainboard

Software

  1. Mobile phone APP

  2. Arduino IDE

Step 2: Building

Wiring

With jumper wire, connect the RGB strip four pins +5V, R, G, B to BLEduino mainboard four pins of +5V, D9, D10, D3 respectively(+5V—–+5V, R—-D9, G—-D10, B—-D3), and the wiring method is as shown in the picture.

Codes and Programming

You can write code on your own, or download the sample code provided by our company, then open it by Arduino IDE, and program the code into BLEduino Mainboard.
The sample code is demonstrated here, and you can download it.

APP Installation and RGB Display

After download the code, install the phone APP and open it (APP has two versions, one is android version, and the other is IOS version), by rotating the APP RGB button, we can control the RGB strip of different colors. The RGB display effect was shown in the video.
