Arduino Basics

In the previous two parts of the this tutorial, we went through a number of simple sketches to get you acquainted with the way that the Arduino handles various data types when passed through the Serial COM port. Here are the main themes from part ONE : Stage One:   Echoing data with the Arduino Stage Two: Using Delimiters to split data. Stage Three: Arduino Maths, simple addition Stage Four: Sending a double to an Arduino, and then doubling it. Stage Five: Sending Sensor data from the Arduino to the Serial Monitor Here are the main themes from Part TWO : Stage Six: ......A simple Processing Sketch Stage Seven:  Arduino and Processing join forces for more fun Stage Eight: A simple project that shows Serial communication from Arduino to Processing In Part Three - we will reverse the direction of communication and get Processing to send data to the Arduino via a USB cable, Stage Nine: A simple processing sketch that switches an LED on the Arduino Stage Ten:   A processing...

      Image source Just had a mini celebration. My Blog just hit 100,000 page-views.  To celebrate this milestone I have given the Arduino Basics Blog a little face lift (just in case you wondering why things looked a little different). If this is the first time you have seen my site, I would encourage you to have a look at my projects page , where you will find some of my Arduino/Processing tutorials and more recently the introduction of Android and Bluetooth.   Thank you to each and every one of you who have spent some time at my site, and I really hope that my effort in putting these tutorials together has either inspired you, or helped you. I have learnt a lot in the process... but this is just the beginning. 

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 ...
