Based on Atmega 16 ultrasonic distance gauge

In order to solve the short distance ultrasonic distance measuring device, measurement accuracy is low, the circuit complex and technically difficult, and difficult to debug and other shortcomings. Article Atmega16 microcontroller as the core, developed a high-precision, real-time response to, a good man-machine interface, communication ability of the ultrasonic range finder. This paper introduces the principle of ultrasonic distance measurement system are introduced in the hardware components and circuit design, complete software system designed to achieve precise range of the range finder. The tests can better achieve distance measurements, have wide application.
