This is an Arduino-based Proximity Sensor circuit wired using the popular HC-SR04 Ultrasonic ranging module ... If everything goes right,you should see the burning eye of the red LED when there is no ...

These fluctuations in skin conductivity are displayed on the Arduino IDE's Serial Plotter, and indicated by the three LEDs ... another for the ultrasonic sensors. The main code is a simple ...

It features two ultrasonic sensors ... in the Arduino IDE, modify the values in the ColorPalette example to match the number of LEDs and your preferred brightness level, and upload the code ...

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 ...

Before I start talking about this really cool thing called Arduino (Italian for "good friend"), let me say a few things about the fascinating subject of physical computing. Physical computing has been ...
