Ultrasonic range finder using 8051.
Simple ultrasonic range finder using microcontroller 8051 presented in this article. This ultrasonic distance meter allows you to measure distances up to 2.5 m with an accuracy of 1 Centi meter. AT89S51 microcontroller and ultrasonic sensor module HC-SR04 forms the basis of this scheme. Ultrasonic module sends a signal to an object, then lifts her echo and the shape of the waves of time period wh ....etc

distance finder based on at89s52 and ultra sonic sensors hc sr04

Ultrasonic range finder using 8051 .
A simple ultrasonic range finder using 8051 microcontroller is presented in this article. This ultrasonic rangefinder can measure distances up to 2.5 meters at an accuracy of 1 centi meter. AT89s51 microcontroller and the ultrasonic transducer module HC-SR04 forms the basis of this circuit. The ultrasonic module sends a signal to the object, then picks up its echo and outputs a wave form whose time period is proportional to the distance. The ....etc

interface lpc 2148 with hc sr04

The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats or dolphins do. It offers excellent range accuracy and stable readings in an easy-to-use package. It operation is not affected by sunlight or black material like Sharp rangefinders are (although acoustically soft materials like cloth can be difficult to detect). Similar in performance to the SRF005 but with the low-price of a Sharp infrared sensor.

Power Supply :5V DC
Quiescent Current : <2mA
Effectual Angle: <15
Ranging Dis ....etc

Pulse-width modulation (PWM) can be implemented on the Arduino in several ways. This article explains simple PWM techniques, as well as how to use the PWM registers directly for more control over the duty cycle and frequency. This article focuses on the Arduino Diecimila and Duemilanove models, which use the ATmega168 or ATmega328.
If you're unfamiliar with Pulse Width Modulation, see the tutorial. Briefly, a PWM signal is a digital square wave, where the frequency is constant, but that fraction of the time the signal is on (the duty cycle) can ....etc
