PIC Based Imaging Sonar
This PIC Based Imaging Sonar use two 40KHz ultrasonic transducers, one for transmit, one for receive. These transducers are steered by an R/C servo over 180 degrees of azimuth.The project using 2 Microchip PIC microcontrollers, a PIC16C71 for the sonar portion, and a PIC16F84 for the servo control. There are two microswitches that sense the ends of travel of the servos, and this information is stored in non-volatile memory on the PIC16F84. It can scan the full 180 degrees, or it will scan just a sector, or it will give multiple readings in a single direction. All control and output is over a single 19.2 Kbps serial port.
