Control your Arduino with voice commands using an Android smartphone! Before we make a voice activated home automation system, we must first learn the basic principles of the experiment. This guide will let you command the Arduino using your Android smartphone and a HC-05 Bluetooth module.
The designer of the app did not include a sample code. I looked for alternatives in Google's PlayStore but none was as good as the app that I've found. Luckily, I was able to figure it out although it took me a while to program it. Sorry IOS users, this app isn't available in Apple's app store :/
How Does It Work?
Have you ever encountered Android's speech recognition? Yes android has one and you can use it to control your Arduino, via Bluetooth. The App works by pressing the mic button, then the it will wait for you to say a command. The app will then display the word's that you've stated and will send data strings for the Arduino to process.
Home Automation System (on July 4, 2014):
A month from now/ I'll be releasing a highly sophisticated home automation + security system. It's my biggest project ever! Our current agenda is to program a better smartphone app that work's like Siri (talks back) and sends strings (data types) to the Arduino via bluetooth. If you want to take a sneak peek of the project and it's concept, kindly skip to the last step. The prototype that I'm working on now is composed of a network of wireless switch boxes that connects to a main control panel via WiFi/ Bluetooth.
Here's A Quick Video Demo:
Step 1: Parts & Materials
Thing that you'll need:
- 5 LED Indicators (the color of your choice)
- Arduino UNO (a clone works fine)
- HC-05 Serial Bluetooth Module
- Solderless Breadboard
- Jumper Cables
