You would have probably read about the SONAR that’s used in ships. By taking the same concept into a small form factor we get a distance sensor. This sensor is available in multiple variants and I’ll ...

Arduino enthusiasts and beginners may be interested in a new add-on board designed for the Arduino Uno microcontroller featuring 10 of the most popular modules and sensors for the Arduino platform.

If you’ve ever had to move around in a dark room before, you know how frustrating it can be. This is especially true if you are in an unfamiliar place. [Brian] has attempted to help solve this problem ...

Tilt sensors are essential components in security alarm systems today. Standalone tilt sensors sense tilt angle or movement. Tilt sensors can be implemented using mercury and roller ball technology, ...

In this experiment we are going to work with a sensor which is a resistor that depends on light. In a dark environment, the resistor will have a very high resistance. As photons (light) land on the ...
