Methodology

This project is divided into two part which are hardware and software.

For hardware part, the component use is ultrasonic sensor also known as transceiver or transducer. A signal is shot from transducer 1 to transducer 2 and timing measured. Immediately, the roles of the transducers are reversed. Now the transducer 2 shoots the signal and transducer 1 receives it, and again timing is recorded.

For this project, the software use is PIC. There are three software files, suffixed ASM (TASM grammar), HEX (MPASM) and OBJ (TASM) The MPASM hex file has configuration and data EEPROM values embedded in it. PIC16F628 microcontroller is pesponsible for generating and sending pulses to the ultrasonic transducers and for timing the return of the received signal. The result of its calculation are shown on LCD.
