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 ...

Introduction: The bluetooth shield used in this project is a great way to detach the Arduino from your computer. What is even better, is that the shield allows you to control your arduino from your mobile phone or other bluetooth enabled device through simple Serial commands. In this tutorial we will connect a Grove Chainable RGB LED to the bluetooth shield directly, and send simple commands using the Bluetooth SPP app on a Samsung Galaxy S2 to change the colour of the LED (Red , Green and Blue) Parts Required: Freetronics Eleven or any compatible Arduino.

This project makes use of the Grove OLED 96x96 display to present a mini-slideshow.  Pictures on your computer are transferred to the OLED via a Processing script, and will cycle through them as many times as you choose.
