An ultrasonic sensor is an instrument that measure the distance to an object using ultrasonic sound waves. An ultrasonic sensor uses a transducer to send and receive ultrasonic pulses that relay back information about an object’s proximity. High-frequency sound waves reflect from boundaries to produce distinct echo patterns and return in varoius direction
Processing Application :
Processing is a flexible software sketchbook application and a language for learning how to code within the context of the visual arts. Since the, Processing has promoted software literacy within the visual arts and visual literacy within technology. There are tens of thousands of students, progrmmers, artists, designers, researchers, and hobbyists who use Processing for learning and prototyping.
