Eight obstacle avoidance robot kits ranked, from a servo-swept ultrasonic Arduino car to a mecanum robot with two infrared sensors plus sonar and a Raspberry Pi that avoids obstacles with a camera, with real specs, honest verdicts and verified Amazon links.
This tutorial shows how to interface the HC-SR04 ultrasonic sensor with Raspberry Pi Pico for contactless distance measurement using MicroPython. The HC-SR04 is a popular and low-cost ultrasonic distance sensor capable of measuring distances from 2 cm to 400 cm with an accuracy of approximately 3 mm. It operates at 5V and communicates using a … Read more
In this tutorial, we will learn to use or interface HC-SR04 ultrasonic sensor with STM32 Nucleo and program it using STM32CubeIDE and HAL libraries. At first, we will take a look at the ultrasonic sensor, then interface it with our STM32 Nucleo and program it for contactless distance measurement using STM32CubeIDE. For demonstration, we will … Read more
In this tutorial, we will learn to interface HC-SR04 ultrasonic sensor with TM4C123 Tiva C Launchpad. HC-SR04 is a contactless ultrasonic based distance or range measurement sensor. It provides an output signal in the form of active high signal and the duration for which the output signal remains high depends on the distance between the … Read more
