nokia N900

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...

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 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,...
