Intro: Control DC Motors With Your Smartphone (Perfect for a Robot)

In this tutorial I’ll show you how you can control 2 DC motors via bluetooth with my brand new Android app.

It’s called “BlueArd” and It’s the 1.0 version. I want to upgrade my app later and add more features.

This app was created with MIT App Inventor. It’s a great place to start with android development.

How It Works:

Step 1: Parts Required

  • 1x Arduino Uno
  • 1x Bluetooth Module (for example: HC-05)
  • 1x Smartphone (any Android will work, I’ve only tested with Samsung Galaxy Ace)
  • BlueArd Application (you can download it below)
  • 1x L293D IC
  • 2x DC motor
  • 1x Breadboard
  • Jumper Cables

Step 2: Schematics

It's really easy to complete this step. You just follow the schematics provided in this picture.

Leave a comment if you have any question.

Step 3: Arduino Code + Android App

Download all my source codes below:
  • Arduino Sketch
  • BlueArd.apk
  • BlueArd Source files (for editing my app with appinventor)
Click Here for Direct Download.

What exactly you need to do? 
Simply download that folder above and unzip it.
Upload the Arduino sketch into your arduino and install the BlueArd.apk file on your smartphone.

Step 4: Final Product!

I got the solution problem bro.... your bluetooth module must be getting disconnecting.. dont use your laptop power to drive the circuit.. Use a much increased D.C source. i.e Adapter

Hi there, I've made a replica of yours and done everything the exact same however when my motors stay motionless no matter what I do. I do have 3 AA's (4.5V) in a 5V port but that shouldn't matter shouldn't it? And also is the wire in the arduino in port 10 or 11?
