Quark is an electrical measurement probe and debugging tool powered by open-source software written in the Arduino environment. Currently featured on the crowdfunding site Crowd Supply, the Quark ...

Measuring an inductor is not something that most multi-meters can do. You usually need a high precision resistor (1% or better) in series with the inductor, a function generator to put a signal ...

Have you ever found the need to measure the capacitance of a capacitor? No multimeter handy (for shame)? Well, as it turns out you can actually measure capacitance using your Arduino Uno, with no ...

This project uses an Arduino microcontroller with an HC-SR04 ultrasonic sensor to measure distances. The Arduino emits ultrasonic pulses and measures the time it takes for the echo to return. This ...

Abstract: We connected $\mathbf{p H}$ sensor and solar cell into Arduino Board to control data transmission via red laser communication or popular known as visible light communication (VLC). The ...
