Arduino Basics

There are many XBee tutorials out there, but I could not find one that I could apply to my specific Arduino/Shield/Xbee configuration. While this particular configuration may not apply to you, perhaps it will send you in the right direction, so please read on. Please note, that your XBee shield may require you to perform extra steps, so please do further reading before jumping in head first. I am not an expert, so don't blame me if you fry your board. The following set of steps worked for me: Step 1: Download and Install X-CTU The easiest way to setup your XBee module is via the X-CTU software from Digi. It can be downloaded from their site here:   http://www.digi.com/support/productdetail?pid=3257 Select  the Diagnostics, Utilities and MIBs section Download and install the XCTU 32-bit ver 5.2.7.5 installer (do a virus check after download) Please note that this is for Windows platforms only ! FYI: We will run the software later Step 2: Upload the bare-minimum scrip...

Description: A 3-axis accelerometer sits at the heart of this project to provide a nifty little motion detector. Want to know who is stealing from the cookie jar? Want a simple home intrusion detector? Or to test your partner's driving skills? Then have a look at this: (Soldering required for this project) Video : Parts Required: Freetronics Eleven or any compatible Arduino Freetronics 3-Axis Accelerometer Module Male header pins Seeed Studio's Grove Base Shield Seeed Studio's Universal Cables Seeed Studio's Grove Button Seeed Studio's Grove Buzzer Mini Breadboard 4.5cm x 3.5cm Protoshield and female header pins 1 x LED 330 ohm resistor Wires 9V Battery + Battery Clip Instructions: Overlay the Seeed Studio Base Shield onto the Freetronics Eleven (or compatible Arduino). Use a Universal Cable to attach a Seeed Studio Grove Button to Analog Pin 0 on the Base Shield. The socket is located directly above the Freetronics Eleven Power plug, and next to the Reset but...

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. Video: Parts required: Arduino UNO or compatible board such as the Freetronics Eleven Seeed Studio's Grove OLED display 96x96 Seeed Studio's Grove Base Shield Seeed Studio's Grove Universal Cables Software required: Arduino IDE version 023 - later versions are NOT supported (at the time of this writing) Processing IDE Seeed Studio's Gray OLED Library - unzip these files and copy them into the Arduino Library folder Sketch: Arduino Sketch: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 41 42 43 44 45 46 47 48 49 50 51 52 53 54 55 56 57 58 59 60 61 62 63 // OLED Slideshow: Arduino Sketch written by ScottC 21/07/2012 #include <Wire.h> #include <SeeedGrayOLED.h> //From ...

In Stages 1 to 5 , we experimented with the Serial Monitor on the Arduino IDE to transmit data to the Arduino and receive data from the Arduino. We performed simple Serial communication of data in both directions. We then moved from transmitting a String of characters to the more difficult task of transmitting a double or a float. Finally, we used the Serial monitor to receive sensor data from our Arduino, and played with a couple of Arduino functions. We will now look at replacing the Serial Monitor with a much more exciting program such as "Processing" which is a free Open Source program that interfaces very easily with the Arduino. It can be downloaded here . We will use a few processing scripts to bring our Arduino Sensor projects to life ! Stage 6: A simple Processing Sketch: BLINK Arduino IDE vs Processing IDE While the processing IDE looks very similar to the Arduino IDE, it is important that you realise that the Processing sketch will run on your computer, and NOT o...

This Tutorial is progressive and will be updated from time to time. The goal is to start from a very basic form of Arduino Serial communication, and progressively add or improve components so that we can ultimately transmit data from one computer to another using an XBee. Please note: I am not an expert, but am happy to share what I have learned. The Arduino forums are a great place to ask questions, feel free to link to this blog (if required). Let us begin. Stage 1: ECHO ECHO                                                                                     Parts Required: Computer USB cable Arduino UNO (or equivalent) Arduino IDE The following code will make the Arduino ECHO anything you send to it.
