Proper tuning requires understanding process characteristics, including time constants, deadtime, and open-loop gain. Load ...

Using an Arduino Nano, ultrasonic sensor, and buzzer, it can sense objects in their way and provide an instant audible alert to them. So they can navigate independently. The best part of this blind ...

Enables autonomous driving of a 2 or 4 wheel car with an Arduino and a Adafruit Motor Shield V2. To avoid obstacles a HC-SR04 Ultrasonic sensor mounted on a SG90 Servo continuously scans the area.

Or, you can buy an ultrasonic cleaning machine and let it do all the work instead. These countertop contraptions—which we have not tested—claim to dislodge food bits, bacteria, and the like ...

HAL-based driver for the HC-SR04 ultrasonic sensor, implemented on an STM32F446RE Nucleo board. Key features include temperature-compensated distance calculation, pulse width validation with hardware ...
