Arduino was born on the Ivrea Interplay Design, and its hardware boards can learn inputs, a finger on a button, turn it into an output, gentle a sensor, activate an LED, arduino if else and way more. The undertaking goals to construct Arduino based mostly RTC by interfacing Arduino and IC DS1307 or DS3231 as timekeeping units. An RTC is powered by a battery and keeps track of time even when there isn't any power. The venture is to construct an 8x6 RGB LED matrix using Arduino Nano, HC-06 Bluetooth Module, and an Android Telephone with a customized app. The Voice-Activated Home Automation mission is carried out using Arduino UNO, Bluetooth, and a smartphone to manage voice commands units. The Voice-Activated Residence Automation system will help us management completely different masses (electrical appliances) with easy voice commands. The motor will rotate in a reverse path if we change the leads. An actual-time clock is a timekeeping gadget current in computers, servers, and other embedded techniques as an Integrated Circuit (IC).
