arduino mega password security system shield
this is a sheild for an arduino mega. this security system can be accesed using RFID and IR and a keypad for the password.
copy the code and get ur IR and RFID UID numbers using the dumpinfo code and then put it in the relevent place don't worry i have putt XX XX XX XX for that type the RFID code and just erasethe other numbers for the ir UID number
u will need: 16x2 LCD DISPLAY, 3X4 MATRIX KEYPAD,ARDUINO MEGA WITH THIS SHEILD,MALE PIN HEADERS,A LOT OF LEAD, MFRC522 RFID READER WITH CARDS OR MABYE TAGS, A 10K POTENTIOMETER.
copy this code and paste it in the arduino software
/* * THIS IS A MULTIPURPOSE PASSWORD SECURITY SYSTEM USING RFID AND A KEYPAD AND A REMOTE. * * IF U WANT TO TYPE PASSWORD, THEN WAIT TILL IT ASKES TO "SCAN CARD OR TYPE" AND TYPE THE NUMBER * IF U WANT TO USE THE CARD THE CARD HAS TO BE REGISTERED FIRST.ALL U HAVE TO DO IS PRESS AND HOLD THE RED BUTTON AND SCAN THE CARD. * OR ELSE U CAN JUST USE THE ARDUINO REMOTE ( 1,2,3 ARE TO SWITCH LIGHT_1,LIGHT_2 AND FAN RESPECTIVELY) (PLUS AND MINUS AND PREV AND NEXT ARE USED TO CLOSE THE SERVO MOTOR) (AND CH AND 0 ARE TO SWITCH ALL THE SYSTEMS AND SWITCH OFF ALL THE SYSTEMS OFF REESPECTIVELY) * * * KEYPAD CONNECTIONS (D1,D2,D3,D4,D5,D6,D7) * IR RECEIVER PIN 10 * SERVO SIGNAL 8 * MFRC522 RST PIN 9 * LCD PINS (A1,A2,A3,A4,A5) * GREEN LED 15 * RED LED 14 * SWITCH 16 * POTENTIOMETER WIPER PIN (VO)OF LCD GND PINS = SERVO(BROWN WIRE) LCD(VSS,RW,K,) MFRC522 GND PIN SWITCH GND PIN IR RECIVER GND PIN POTENTIOMETER GND +5v PINS = LCD (VDD,A) SERVO (RED WIRE) SWITCH +5V PIN IR RECIVER VCC PIN 3.3V PINS = MFRC522 VCC PIN ONLY * Typical pin layout used: * ----------------------------------------------------------------------------------------- * MFRC522 Arduino Arduino Arduino Arduino Arduino * Reader/PCD Uno/101 Mega Nano v3 Leonardo/Micro Pro Micro * Signal Pin Pin Pin Pin Pin Pin * ----------------------------------------------------------------------------------------- * RST/Reset RST 9 5 D9 RESET/ICSP-5 RST * SPI SS SDA(SS) 10 53 D10 10 10 * SPI MOSI MOSI 11 / ICSP-4 51 D11 ICSP-4 16 * SPI MISO MISO 12 / ICSP-1 50 D12 ICSP-1 14 * SPI SCK SCK 13 / ICSP-3 52 D13 ICSP-3 15 -------------------------------------------------------------------------------------------- */ #include <IRremote.h> #include <Servo.h> #include <deprecated.h> #include <MFRC522.h> #include <MFRC522Extended.h> #include <require_cpp11.h> #include <SPI.h> #include <MFRC522.h> #include <LiquidCrystal.h> #include <Keypad.h> #define SS_PIN 53 #define RST_PIN 9 #define BUTTON_PREV 0xFF22DD #define BUTTON_next 0xFF02FD #define BUTTON_PLUS 0xFFA857 // type the ir numbers here #define BUTTON_MINUS 0xFFE01F // example : 0x XX_XX_XX #define redLED 14 //define the LED pins #define greenLED 15 #define LIGHT_1 22 #define LIGHT_2 24 #define FAN 26 #define SD_ChipSelectPin 17 char* password ="32369"; //create a password int pozisyon = 0; //keypad position int RFIDState= 0; int SENSORState=0; int RECV_PIN = 10; const byte rows = 4; //number of the keypad's rows and columns const byte cols =3; const int RFID = 16; const int SENSOR = 17; char keyMap [rows] [cols] = { //define the cymbols on the buttons of the keypad {'1', '2', '3', }, {'4', '5', '6', }, {'7', '8', '9',}, {'*', '0', '#',} }; byte rowPins [rows] = {1, 2, 3, 4}; //pins of the keypad byte colPins [cols] = {5, 6, 7, }; bool door = true; Servo myservo; IRrecv irrecv(RECV_PIN); decode_results results; MFRC522 mfrc522(SS_PIN, RST_PIN); Keypad myKeypad = Keypad( makeKeymap(keyMap), rowPins, colPins, rows, cols); LiquidCrystal lcd (A0, A1, A2, A3, A4, A5); // pins of the LCD.
