Arduino Basics

PART FOUR The Video This is part 4 of my tutorial on designing an Android Phone Bluetooth App using the Android/Processing language. The App sends information to an Arduino via Bluetooth after pressing a button on the phone. The RGB LED attached to the Arduino Uno (or compatible board) will change colour depending on the button being pressed on the phone. The Arduino gains Bluetooth capabilities through the Seeedstudio Bluetooth shield ( which can be found here ). Parts 1-3 of the tutorial were designed to take you step-by-step through designing the app. If you are wondering what you missed, here is a summary: This is what you'll find in partone : Downloading and setting up the Android SDK Downloading the Processing IDE Setting up and preparing the Android device Running through a couple of Processing/Android sketches on an Andoid phone. This is what you will find in part two : Introducing Toasts (display messages) Looking out for BluetoothDevices using BroadcastReceivers Getting ...

PART THREE If you happened to land on this page and missed PART ONE , and PART TWO , I would advise you go back and read those sections first. This is what you'll find in partone : Downloading and setting up the Android SDK Downloading the Processing IDE Setting up and preparing the Android device Running through a couple of Processing/Android sketches on an Andoid phone. This is what you will find in part two : Introducing Toasts (display messages) Looking out for BluetoothDevices using BroadcastReceivers Getting useful information from a discovered Bluetooth device Connecting to a Bluetooth Device An Arduino Bluetooth Sketch that can be used in this tutorial InputStream and OutputStream We will now borrow some code from the Android developers site to help us to establish communication between the Android phone and the Bluetooth shield on the Arduino. By this stage we have already scanned and discovered the bluetooth device and made a successful connection. We now need to create ...
