Most often ultrasonic transducers are used for distance measurements, and in the DIY world, usually as a way for robots to detect obstacles. But for a weekend project, [Vinod.S] took the ultrasonic ...

The main goal of this application is to design an ultrasonic qualitative distance estimation sensor using Dialog Semiconductor’s SLG47105V. The system is designed using high-voltage (HV) macrocells ...

Although ultrasonic sensors have been around for several decades, their popularity in sensing applications continues due to their capability, flexibility and relatively low cost. Products like ...

This series of projects explore concepts of radio communications. We use LEDs to generate (very high frequency) radio waves and photo-resistors to take the place of radio antennas. These ideas are ...
