Estimate ocean wave height (or vessel heave), waves direction, and period from accelerations using IMU on esp32 using advanced Kalman filters

This repository contains a curated set of coding problems and solutions to help you prepare for TCS recruitment exams like NQT, Ninja, and Digital.

Monitor sound frequencies in real time using Arduino UNO inbuilt Analog Comparator

C++ Library for Audio Digital Signal Processing

my own audio visualizer (library), because after effects sucks

Melody player & scaling

Arduino library for the TSL235R light to frequency convertor

Advanced Arduino Frequency Scanner This project upgrades the basic pulse‐counting scanner into a high‐resolution, wide‐range instrument using Arduino’s Timer1 Input Capture. You’ll get instant period readings, automatic smoothing, dynamic range up to several MHz, and a clean I²C LCD interface.

APDOB - Adaptive Periodic-Disturbance Observer

Frequency display of ADC data on ESP32 for tuning musical instruments

LibGaussianBlur is a C++ and Py library designed to apply Gaussian blur to images using the Fast Fourier Transform (FFT)

Arduino project to measure mains/grid frequency and publish it as SSE and MQTT streams

This project involves the creation of a jamming device using a Digispark USB development board. The repository includes scripts and code that enable the Digispark device to disrupt various wireless signals, such as Wi-Fi or Bluetooth, for educational and testing purposes. The project aims to demonstrate the vulnerabilities of wireless communication

Program drawing given server response time on chart.

This is an example app for the CustomMatPlot Library.

A simple MEMS I2S microphone and audio processing library for ESP32.

This project implements a versatile waveform generator using an ESP32 microcontroller. It generates various types of waveforms with adjustable parameters such as frequency, amplitude, and phase. Additionally, it features sweep and burst modes for more complex signal generation.

FIR and IIR digital filter design tool. Available on the Mac App Store.
