A standard electret microphone can detect sub-audio "sounds" when some simple equalization circuitry is added.

Figure 1. Left—SpectroMarine sensor schematic, a—detection window with spectrometers and CMOS camera, b—window with LEDs for fluorescence excitation, c—mounting holes. Right—part of user-accessible ...

Ever wished your Arduino could send you an SMS alert when something important happens—like an intruder detected by your DIY security system, or a gas leak in your kitchen? With just an Arduino UNO R4 ...

One of the more interesting applications of this circuit would be to replace or to realize a smart sensor with Arduino. The 4…20 mA standard was introduced a few decades ago, to replace the existing 3 ...

Abstract: In order to simplify the complexity of ultrasonic and electromagnetic wave signal detection and improve the accuracy of partial discharge detection of power equipment, a sensor design idea ...

“Uno R4 WiFi includes an error-catching mechanism that detects run-time crashes and provides detailed explanations and hints about the code line causing the crash,” according to Arduino – Electronics ...

This build is about using the temperature sensor in your clock. The ATMega328p, the chip at the heart of all your Arduino Uno clones, has within it a watchdog timer that clicks over at a rate of ...
