Audio Peak Detector with FFT Visualization Overview This script implements a real-time audio spectrum analyzer and peak detector using the microphone on the Arduino Nicla Vision board. It provides ...

README.md ECG-R-Peak-detector ECG R-peak detecting with Arduino Uno We used ECG sensor which is self-made. Depending on Arduino input voltage (0V ~ 5V) -> End of the sensor circuit, there is a ...

The Arduino needs a little help to read the pulses from the tube in the form of a simple circuit. The circuit acts as a peak detector and the peaks last only about twenty microseconds.

This audio peak detector allows a pair of stereo channels to be monitored on a single LED.Identical circuitry is used in the left and right channels. Use is made of the switching levels of Schmitt ...

In this paper, a new fast peak detector for single or three-phase unsymmetrical voltage sags is proposed. The proposed detector is modified from a single-phase digital phase-locked loop based on a d-q ...
