To supply targeting data for the launcher, an Arduino Uno uses an ultrasonic sensor pair mounted atop a servo. As the servo rotates, the returns from the ultrasonic sensor are plotted on a screen ...

Inside [Klaus]’ device is an Arduino Uno, an HC-SR04 ultrasonic distance sensor, and an Adafruit Wave Shield. Originally, this parking/distance sensor used a small TFT to display the distance to ...

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 ...

Beginners can readily understand and tweak the code to more accurately set the different conductivity ranges. Powered by an Arduino Uno ... closing the lid, an ultrasonic sensor in front of ...

The Arduino code mainly consists of function declarations ... with only an Arduino UNO, ultrasonic sensor, force-sensitive resistor (or push button), and piezo buzzer. The tone generated depends ...

The official Arduino Blog has this week featured a new project which demonstrates ultrasonic Arduino to Arduino ... together with a pair of Arduino Uno development boards to transmit text short ...
