Arduino is an open source micro-controller board designed for technical as well as non technical user. School level students to the engineering students and other non technical persons and hobbyists are taking the advantage from the Arduino microcontroller. The today's educational system can be improved by this device and this is fun too. I have posted some simple tutorial about arduino microcontroller with simple projects but today i am going to post a little bit difficult project here. This projects utilizes the serial communication between arduino and computer and the arduino output
can be controlled by computer. Lets explain slowly.
