RFID? What is RFID? How to use RFID with Arduino? How Does RFID Works? These are the questions which we are going to Answer Today. RFID stands for R(Radio) F(Frequency) Id(Identification) thus meaning RFID = Radio Frequency Identification. Use of RFID: 1. RFID is one method for Automatic Identification and Data Capture 2. Track Progess in Assembly Line 3. Managing supplies in Warehouse and many more. Components of RFID Module: As we discussed earlier, RFID stands for Radio Frequency Identification. RFID Module has two components namely: 1. RFID Reader 2. RFID Tag Describing the Components of RFID Module: 1. RFID Reader: It consist of a Controlling circuit + RF Module + Antenna Coil. It is used to generate High Frequenct RadioWaves or Electromagnetic Waves 2. RFID Tag : It consist of an Embedded Circuit + Antenna Coil. It is a passive element and is used to transfer data to the RFID Reader Working of RFID Module: The step by step working of RFID is as given: ...

THE FOLLOWING TUTORIAL VIDEO SHOWS YOU  THE VARIOUS DETAILS OF THE IR SHARP SENSOR OR THE IR DISTANCE SENSOR. IT IS BASICALLY USED OT MEASURE DISTANCE IN THE RANGE OF 10-80 CM. BELOW 10 CM, IT DOES NOT MEASURE DISTANCE ACCURATELY, AND THUS THIS REGION IS CALLED BLIND SPOT. THE PIN DIAGRAM FOR THE SENSOR IS AS FOLLOWS: 1. PIN 1 - DATA PIN CONNECTED TO PIN A0 OF ARDUINO 2. PIN 2 - GND PIN 3. PIN 3 - VCC PIN ONCE THE CONNECTIONS OF LCD AND SHARP SENSOR ARE DONE, YOU NEED TO UPLOAD THE FOLLOWING CODE ONTO YOUR ARDUINO BOARD. CODE: #include<LiquidCrystal.h> LiquidCrystal lcd(14,15,16,17,18,19); #define sharp A0 void setup() {   Serial.begin(9600);   lcd.begin(16,2);   lcd.clear();   lcd.print("Sharp Sensor ");   lcd.setCursor(0,2);   lcd.print("Interfacing");   delay(2000);   lcd.clear();   lcd.print("Arduino Tutorial");   lcd.setCursor(8,2);   lcd.print("By:");   delay(2000);      lcd.clear();  ...
