Introduction: 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.
