See the video → ← What we need? And this is the voltage across my ultrasonic receiver (measured directly on the pins): After 2.5m, the amplitude of the voltage generated by the sound is less or equal to that 100mV, so, I can't get a properly response. Log in or register to post comments; Top. We are using L293D motor driver IC to drive motor since Arduino won’t be able to supply enough current to drive a DC motor. While it looks like a continuous line, it’s actually composed of many individual measurements. Utilizing Transmit Receive Switches Effectively DigiKey. Ultrasonic Proximity Detector Electronics For You. I found a big difference in the 'echo' signal when using the drive transistor pair for the transmitter, when using a decent OPA receiver, ie: CA3240. The signal is then amplified by IC1:A and IC1:B. IC1:A is self-biasing via C2 & R5. In the ultrasonic range finder, there is a transmitting transducer and receiving transducer. This signal is then demodulated to get the data and is sent out through the data pin.
