Serial Port The microcontroller AT89C51 has an inbuilt UART for carrying out serial communication. The serial communication is done in the asynchronous mode. A serial port‚ like other PC ports‚ is a physical interface to establish data transfer between computer and an external hardware or device. This transfer‚ through serial port‚ takes place bit by bit. IBM introduced the DB-9 RS-232 version of serial I/O standard‚ which is most widely used in PCs and several devices. In RS232‚ high and

1. INTRODUCTION The National Heart‚ Lung‚ and Blood Institute states that “more than a million persons in the U.S. have a heart attack and about half (515‚000) of them die in each year. About one-half of those who die do so within 1 hour of the start of symptoms and before reaching the hospital”. A heart attack happens to a person when the blood flow and oxygen supply to heart muscle is blocked‚ and it is mostly caused by the Coronary Artery Disease (CAD). CAD occurs when the arteries that supply

is to design a control mechanism by which the propellers would rotate at a constant speed‚ at varying wind speeds by adjusting their pitch. This would be achieved by using wind sensors (anemometer) and a microcontroller. The sensors would measure the wind speed and feed that to microcontroller which would in turn calculate the pitch of the propellers to keep them rotating at constant speed. (Optional) After these parts of the project have been realised‚ we would enhance our project by aiming to
