The quick road test, oh it’s a simple approach to display the distance measurements on the Arduino Serial Monitor. I will use this sensor (or its latest version) in a more complex project in the next ...

Instead, it relies on an ultrasonic distance sensor to detect a hand (or foot) waved in front of the door. An Arduino Leonardo runs the show, sounding a buzzer when the ultrasonic sensor is triggered.

Ultrasonic Sensor Measurement: The HC-SR04 ultrasonic sensor measures the distance to an object by emitting a sound wave and measuring the time it takes for the echo to return. The sensor is connected ...

One of the common applications of ultrasonic sensors is parking assistance systems of automobiles by using an Arduino UNO board, HC-SR04 sensors, RGB LEDs and Buzzers. Assume that four distance ...

Buy arduino, buy sound shield, buy distance sensor shield, plug into each other, burn example code, stuff components inside box. Not only is this not a hack but he might as well have just bought a ...

The Arduino board is used as a wearable. This is fitted with a module-sized set of ultrasonic sensors. The sensor allows people who are blind to effortlessly navigate their surroundings and identify ...
