The nano sensor interface presented below is a microcontroller-based universal sensor interface with a power-saver mechanism. The idea, centered around an Arduino Nano (v3) microcontroller, was ...

An intelligent obstacle avoiding robot built with Arduino ATmega328 that uses an HC-SR04 ultrasonic sensor mounted on a micro servo for 180° environmental scanning and autonomous navigation. This ...

Ultrasonic range sensors can have varying fields of view. Some are around 15deg and some can be nearly 90deg. Multiple sensors mounted at different angles is superior to scanning for fast robots.

This project uses an Arduino Uno and an HC-SR04 ultrasonic sensor to measure the distance of nearby objects and display it on a 16x2 LCD. If an object is too far, it shows “Seems safe ... 💡 ...
