Sparkfun.com has recently released a simple, easy and useful robot platform for robotics amateurs. It is called "Magician Chassis". You can use the chassis for different kinds of robots, for example, line sensing, obstacle detecting and smart phone controlled robots. I have recently published an easy project about smart phone controlled robot. I have also used Magician Chassis on my project. I recommend this chassis for robotics amateurs and novices because it is cheaper than other products I have...

With this project/application, you can make a light sensor dependent lamp. You can make a light sensor or dark sensor with this application. The light sensor of your Android smart phone senses ambient light present in your room and sends commands to Arduino board. Your Arduino program determines the behaviour of the LED, whether it should glow bright or dim. You can also see the light sensor data on the smart phone interface. If you have never worked with Amarino before, I strongly recommend...

In this project, you can control an LED and see sensor graph simultaneously. For your convenience, I have used a simple light sensor circuit. The resistance of the photo resistor varies with the amount of light falling on it. The amount of light is varied with LED controller and the sensor data variation can be seen on the Sensor Graph. If you have never worked with Amarino before, I strongly recommend you to visit www.amarino-toolkit.net and try the basic projects published on that site. After...

If you have never worked with Amarino before, please visit www.amarino-toolkit.net and follow the instructions given on that site. Before trying this project, please read this post: http://www.buildcircuit.com/multi-color-lamp-using-amarino-android-and-arduino/   In this application, you can set MAC ID of  different Bluetooth modules. You don't need to edit the source codes to change the MAC ID. If you don't want to see the source codes, you can control an RGB LED with these...

With this experimental setup you can send some text messages from your android phone to arduino and vice versa. Basically, whatever you can see on Arduino's Serial Monitor can also be seen on the interface of Bluetooth Application that I will recommend on this article. The recommended application for this experiment is S2 Bluetooth. You can get this application for FREE. You can try this experiment with some other FREE applications also.

Some posts on this site are about serial communication between Nokia N900 and arduino. You can read about transferring data between Nokia N900 and arduino from this link: http://www.circuit-blog.com/how-to-use-nokia-n900-and-arduino-for-controlling-electronic-devices/ This time I am going to share 3 extremely useful and FREE applications that can be used for serial data transfer between your android phone and arduino. Read about a simple experiment from this link: http://www.circuit-blog.com/bluetooth-communication-between-android-and-arduino-using-free-applications/ You...

This tutorial is for novices who have never made any Android application or worked with amarino. I strongly recommend you to work with SensorGraph before you start doing this project. For doing SensorGraph project, please click on the following link: How to Make SensorGraph We need following components/equipments for this experiment: a. Android Smart Phone- I am using ZTE Blade. See the operating system specifications on the given link. Quite cheap and good looking. b. Arduino Duemilanova...

WWW.CIRCUIT-BLOG.COM Here's a very simple program to display some characters/strings on 16x2 LCD using Nokia N900 terminal and arduino. You will need following devices for this experiment. a. Nokia N900 b. Atmega328 chip c. Blue Smirf Bluetooth Module d. 16x2 LCD e. FT232RL breakout board Arduino Side Step 1: Make arduino programmer on breadboard- CLICK HERE. On this page, you will see how to connect LCD to arduino. Step 2: Change the Baud Rate of Bluesmirf Bluetooth Module- CLICK HERE Set...

This tutorial gives extremely simple easy for changing the baud rate of your BlueSMiRF Gold/silver bluetooth module. In this article, I have presented the baud rate changing steps done on Windows 7. Connection of Bluesmirf TX- RX of arduino RX-TX of arduino VCC- VCC of arduino GND-GND of arduino Connect CTS-I to RTS-O After connecting the bluetooth module, you should see RED light blinking on the board. I have used bluetooth shield, but you don't really need it. Then,...
