It does its job using an ultrasonic distance sensor and an Arduino Pro Mini. The bracelet has two feedback modes: audio and haptic.

This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module,used here for non-contact object detection purpose. The HC-SR04 module includes ultrasonic ...

At this point, note that Mode 1 (Default Mode) uses the echo & trigger pins like a standard ultrasonic sensor whereas Mode 2 (TTL Serial Output Mode) uses software serial. So, if you wish to use Mode ...

Ultrasonic sensor powered by Arduino UNO The servos should not be powered by the Arduino directly due to insufficient current supply, which could damage the voltage regulator. Instead, an external ...

// Written by AnyalogbuEC for demonstration purposes. // This program measures distance using an ultrasonic sensor. // Visual indication of distance is provided by an LED. // The distance is also ...

Designed for short-range applications from 2" to 6", the RPS-400-6 ultrasonic sensor measures 0.75" x 2" x 1.5" and comes standard with integrated background suppression.
