The authors propose a radar made with the ultrasonic sensor type HC - SR04, developed for Arduino. The novelty added by this paper is the development of specific libraries aiming to interface the ...

Abstract: We present an ultrasonic transducer interface IC that includes an 8-bit, 40 V pp, 400 mA current output DAC for arbitrary waveform transducer excitation and a ±25 V analog multiplexer. The ...
