All In One Clock 2.0

Alarm app for PSP (WIP)

This library enables you to use RTC from RTL8720-based boards such as RTL8720DN, RTL8722DM, RTL8722CSM. This RTL8720-based RTC, using Interrupt, has no battery backup. Time will be lost when powered down. To need NTP-client to update RTC every start-up.

This repository contains the code for a comprehensive security system based on IoT nodes with ESP32 microcontrollers. It consists of master and slave nodes, along with a mobile application for remote control. The system detects intrusions via motion and door sensors, activates alarms, and provides a user-friendly interface for managing security.
