PART -2 BEFORE READING THIS POST  I think you guy's already read part 1  If you didn't,Tap on the below 👇 pic To get a basic outline 🤔 The below project is done by me  ON JUN 10 2022 Arduino Beginner's Guide Arduino: The Beginner's Guide to Physical Computing Arduino is an open-source electronics platform based on simple, easy-to-use hardware and software. It is designed for anyone to build digital devices, from beginners to experts. With Arduino, you can create interactive devices that respond to sensors, control lights, motors, and more. In this article, we'll introduce you to the basics of Arduino, what it is, how it works, and why you might want to use it. What is Arduino? Arduino is a microcontroller board that can be programmed to interact with the physical world through inputs like sensors and outputs like lights, motors, and displays. A microcontroller is a small computer that can run one specific program at a time. In the case of Arduino, the program is w...

WHAT IS R.F.I.D !........ Radio Frequency Identification (RFID) uses electromagnetic fields to automatically identify and track tags attached to objects. An RFID system consists of a small radio transponder, a radio receiver and a transmitter. When triggered by an interrogating electromagnetic pulse from a nearby RFID reader, the tag sends digital data (usually an identifying inventory number) back to the reader. This number can be used to track inventory items.  Passive tags are powered by interrogating radio waves from an RFID reader. Active tags are battery powered and can be read by RFID readers from up to hundreds of meters away. Unlike bar codes, labels do not have to be in the reader's field of view, so they can be incorporated into tracked objects. RFID is one method of automatic identification and data collection (AIDC). RFID tags are used in many industries. For example, RFID tags attached to cars during production can be used to track assembly line progress, RFID tagged...

  WHAT IS:-(N.F.C) !............. Near Field Communication (NFC) is a set of communication protocols that allow two electronic devices to communicate over a distance of 4 cm (112 inches) or less. NFC provides low-speed connectivity through a simple setup that can be used to bootstrap higher-performance wireless connections. Like other "proximity card" technologies, NFC is based on inductive coupling between two so-called antennas present in NFC-enabled devices (such as smartphones and printers) rotating in one or both directions at a frequency of 13.56 MHz. . A globally available, unlicensed radio frequency ISM band using the ISO/IEC 18000-3 air interface standard with data rates from 106 to 424 kbit/s. The standard was provided by the NFC Forum. This forum was responsible for promoting technology, setting standards, and certifying device compliance. If it meets the criteria to be considered a personal area network, it can be used for secure communication by applying encryp...
