[Klaus] wanted some sort of aid for parking his car, and after running across a $4 ultrasonic sensor, decided to build his own speaking distance sensor (.de, Google Translation). Inside [Klaus ...

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 ...

Ultrasonic sensors are an inexpensive way to make robots see. The sensors send out sound waves to detect objects. While both glass and most plastics are solid objects that impede sound, acoustically ...

The sensors attached to the Arduino had an approximate scanning range of 3m, and the ultrasonic units were modified to broadcast an analog signal at 40 kHz.

Seeing as Arduino is good for controlling motors and sensors, Randy added a PING ultrasonic sensor to the front of the vehicle too.

With the Arduino-based open source project looking for crowd-funding on the Kickstarter website, the AI robot kit has an integrated HD camera and ultrasonic sensor to allow it to recognise and track ...

Arduino-powered obstacle-avoidance cars made by learners at Karare AIC CDC school in Marsabit./STEPHEN ASTARIKOA quiet transformation is unfolding at Karare AIC CDC Primary School in Marsabit.In a ...

For the physical feedback, Denver has made some vibrating boxes that you put in your pockets. An Arduino polls the ultrasonic sensors and provides feedback via the boxes. This completely frees up the ...
