...For instance, in a low-power IoT sensor hub application scenario, ESP32 is woken-up periodically and only when a specified condition is detected. The low-duty cycle is used to minimize the amount of energy that the chip expends. The output of the power amplifier is also adjustable, thus contributing to an optimal trade-off between communication range, data rate and power consumption. The ESP32 series is available as a chip or module. You can use Arduino-ESP32 Online Documentation to get all information about this project.

...This project provides a very low-cost open-source "Hardware and Software" for a Cardiac Rhythmic Holter. The hardware has been made very simple and is based on an Arduino Nano micro-controller with boards for SD card mass-storage, instrumentation differential amplifier and RTC. It can help monitoring arrhythmia syndromes such as bradycardia, tachycardia, extra-systoles, pause or flutter. WARNING: In no case it can be use to replace a professional medical examination. Device MUST NOT BE CONNECTED to appliance powered by mains - risk of electrical shocks ************************************************************************************** see also: ECG Logger Viewer application : https://sourceforge.net/projects/ecg-logger-viewer/

An open-hardware and -firmware project that implements a USB-input fully-digital class-D audio amplifier. All processing is done on FPGA, including the USB-physical, USB-SIE, HID interface, clock-recovery, bus voltage regulation, noise-shaping and PWM output. A Microchip PIC based remote control is also included. The remote maps to the media buttons of the USB HID interface. The volume control, next track, previous track, stop and play/pause functions are supported.

This project experiments with C language to discover and design a programmable guitar amplifier effects micro controller computer section of a tube and solid state designed guitar amp. This a collaboration electronics project with my son. The goal of this project is to use Arduino hardware with C language programming to manipulate the guitar signal by various effects of phaser, flanger, reverb, digital delay and echo, and tremelo.

This is a tiny module for embedding in a replica M41A prop from the Alien series of movies. Based around the PIC32MX695F512H chip it has 512KB of flash for sample storage, a 12 bit DAC module and 1.8W audio power amplifier, dual 14.4mm red 7-segment LED display, plus a whole host of additional features.
