Ultrasonic Security System

June 29, 2012 By: admin Category: AVR, Microcontroller, Security System No Comments →

This portable security system is built based on Atmega644 microcontroller. It can detect intruders based on their physical presence. The system uses URM37v3.2 ultrasonic sensor which is connected to MCU through rs232 serial communication. To rotate sensor for wide coverage range, the system is equipped with Parallax servomotor. For user interface, there are LCD and […]

AVR Ultrasonic Spheroid Levitation Device

April 28, 2012 By: admin Category: AVR, Game, Microcontroller, Miscellaneous, Project No Comments →

The goal of this project was to design and build a ‘gaming’ device capable of levitating a ping pong ball at varying heights based on the proximity of the user to the device. The project based on ATMega16 microcontroller. The project incorporates a fairly complex mechanical system and utilizes many features of the ATmega platform […]

Interfacing SRF05 with AVR ATmega32

April 23, 2011 By: admin Category: AVR, Interfacing, Measurement, Microcontroller, Project, Sensor No Comments →

Recently, Jaime Andres Arteaga designed a simple C program to use a SRF05 ultrasonic sensor, low cost ultrasonic rangefinder up to 5 meters, with AVR ATmega32. The microcontroller sends a pulse trigger (10 us minimum) and then, the sensor produces a pulse that is proportional to the distance.

PIC Imaging Sonar

February 13, 2011 By: admin Category: Detector, Digital, Microcontroller, PIC, Project, Sensor No Comments →

This imaging sonar project uses two PIC microcontrollers, PIC16F84 for the servo control and PIC16C71 for the sonar portion. It’s equipped with two 40 KHz ultrasonic transducers, one for transmit, one for receive. These transducers are steered by an R/C servo over 180 degrees of azimuth.
