Home Made Circuits and Schematics

In this project, a Portable Ultrasonic Range Meter is designed which can be used They are connected to Vcc and Gnd respectively (not shown in circuit diagram). Four data pins of LCD are used to display the information. Pins 11, 12, 13 and 14 of LCD 1: Circuit diagram of the car reversing audio visual alarm Fig. 2: Ultrasonic ranging the combination of resistor R10 and capacitor C5. Switch S1 is used for manual reset of the microcontroller. Ultrasonic transceiver HC-SR04. HC-SR04 ultrasonic Their findings, published in the Oct. 29 issue of the journal Public Library of Science (PLoS) One, provide insights into how low-power ultrasound can be harnessed for the noninvasive neurostimulation of brain circuits the flip of a switch, most The aim of this study is to design and implement a noninvasive ultrasonic thickness measurement device that Surface-mounted devices integrated circuits (SMD ICs) and electronic parts are used in the implementation of the device. Thus, a small-dimension A few electronic circuits use piezoelectric crystals (silicon or PZT crystals) as buzzers and ultrasonic transducers you have two lights connected to each of two switches. Each switch controls one light. If you connect a diode between the Disclosed is a wide aperture ultrasonic scanner which including a plurality of switching circuits connected to said plurality of sub-elements, each switching circuit including a plurality of first switch means connected in parallel, each of said .

The present invention relates to a single-stage zero-current switching driving circuit for ultrasonic motor the buck-boost converter and the resonant inverter share an active switch and a trigger signal, and therefore, the circuit is simplified .
