Project summary:   MQ2 gate sensor is analog type sensor which can detect LPG, Methane, CO2 and Smoke in Air. In this project we are going to calibrate LPG, CO and Smoke PPM in the air and display these values on the Nokia 5110 LCD screen. Figure 1 : MQ2 gas sensor with Nokia5110LCD In this project when you will exhale breathe on it or put a cigarette lighter near it then LCD screen reading would change. Component required: - This project is based on the Arduino uno board and we are interfacing MQ2 gas sensor with Nokia 5110LCD so we would required component which are described below. Components list:       ·           Arduino board.       ·           Arduino software.       ·           MQ2 gas sensor.       ·       ...

RFID MFRC522  Door lock system Project summary: RFID system radio frequency identification in which Information is written in the card or tag is get read by RFID module when they get in contact. In this project we are making a home lock system which would open only when an authorized card will be available and access will be denied on wrong card. Component require: - In this project we are interfacing Arduino board with RFID MFRC522 and servo motor. RFID system would send data to Arduino board and according to that data action would be taken by Arduino board. Components are listed below:         ·          Arduino board.         ·          Arduino software.         ·          RFID MFRC522 board.         ·        ...
