It has a range of 2cms to 400cms. The project is build around AT89S52 which 8051 based microcontroller. The distance is displayed on Seven Segment Displays.The working of the ultrasonic sensors is quite simple and they are easy to interface with the microcontroller. The sensor module has 4-pins out of which Pin-1 and Pin-4 are +Vcc and Gnd respectively.Pin-2 is Trigger and Pin-3 is Echo pin.When a High pulse of 10us is applied at TRIG pin, the ultrasonic transmitter sends 8 consecutive pulses of 40kHz frequency. As the Eighth pulse is sent the ECHO pin of the sensor becomes HIGH. Now when the ultrasonic waves reflect from any surface and are received by the Receiver,  the ECHO pin becomes LOW.

Every year millions of computing systems are built destined for desktop computers (Personal Computers, workstations, mainframes and servers) but surprisingly, billions of computing systems are built every year embedded within larger electronic devices and still goes unnoticed. Any device running on electric power either already has computing system or will soon have computing system embedded in it.

With microcontrollers, one gets a complete miniature computing system on a single integrated circuit. The CPU, RAM, ROM and Input / Output peripherals all on a single thumb size SoC. This very popular approach to learning embedded design and development is in fact just the one side of the complete picture. Working with microcontrollers (and microprocessors) is all about software-based embedded design.

And familiarity does not necessarily beget understanding. So what exactly is FPGA?In simple terms it is a logic chip which contains a two dimensional array of logic cells and programmable switches. They are ICs that contain an array of identical logic blocks with programmable interconnections.Just as on a blank canvas you can paint any picture you want, FPGA allows an engineer to design any digital circuit. They say: just generate the bit file, download it and you’re good to go! This is a big development over the traditional microcontrollers as the architecture of such controllers does not support larger designs. For example, microcontrollers like 8051 used Harvard architecture with CISC instruction set. FPGA does not have any inbuilt instruction sets which provide the designer with much greater flexibility. A controller has its own CPU which starts the controller, retains memory and performs several tasks. Unlike microcontrollers, a FPGA will not be able to start functioning on itsown due to lack of the traditional architecture.
