Secret RFID Iphone box

Here's a video of it working: https://streamable.com/2jgh7 Make your own secret stash hidden as nothing more than an empty iphone box. Lock the box by sticking either of the two rfid tags over the reader (bottom left corner of the box). Unlock it by putting a specific pattern of, in my case, the blue rfid tag, wait two seconds, the white rfid tag, wait two seconds, and then the blue rfid tag again. This can be changed to any two of your own rfid tags in the code or just one instead of two.  I originally made this to be used in an escape the room I made for my friends, it worked flawlessly and it sure took them a while to figure out. Feel free to use it for whatever you like.   There are two models included, one for aligning the locking frame, and the actual locking frame itself Materials:  wires https://amzn.to/2x77Q1u arduino uno https://amzn.to/2OdlFCD 9 volt battery or alternative power source https://amzn.to/2Nzmqc9 power source for arduino (a 9 volt battery, wire leading outside the box to a wall, etc.) https://amzn.to/2oYzmdO 1 or two rfid tags of any type https://amzn.to/2N9tKMf an rfid reader https://amzn.to/2oZx1iF mini servo motor https://amzn.to/2QkufRE heres the code: //Written by Neil Sawhney #include #include #include #define SS_PIN 10#define RST_PIN 9MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance.Servo openServo;int openPattern = 0;void setup(){openServo.attach(7);openServo.write(78);Serial.begin(9600); // Initiate a serial communicationSPI.begin(); // Initiate SPI busmfrc522.PCD_Init(); // Initiate MFRC522Serial.println("Put your card to the reader...");Serial.println(); }void loop(){// Look for new cardsif ( ! mfrc522.PICC_IsNewCardPresent()){return;}// Select one of the cardsif ( ! mfrc522.PICC_ReadCardSerial()){return;}//Show UID on serial monitorSerial.print("UID tag :");String content = "";byte letter;for (byte i = 0; i {Serial.print(mfrc522.uid.uidByte[i] Serial.print(mfrc522.uid.uidByte[i], HEX);content.concat(String(mfrc522.uid.uidByte[i] content.concat(String(mfrc522.uid.uidByte[i], HEX));}Serial.println();Serial.print("Message : ");content.toUpperCase();if (content.substring(1) == "3D 29 83 B2") //change here the UID of the card/cards that you want to give access{if (openPattern == 0) {openPattern = 1;Serial.println("step 1");if (openServo.read() == 78){openServo.write(166);openPattern == 0;}delay(1000);} else if (openPattern == 1) {openPattern = 0;Serial.println(" Access denied1");if (openServo.read() == 78){openServo.write(166);openPattern == 0;}delay(1000);} else if (openPattern == 2) {Serial.println("Authorized access2");Serial.println();openServo.write(78);openPattern = 0;delay(1000);}} else if (content.substring(1) == "45 A7 D7 15"){if (openPattern == 0) {openPattern = 0;Serial.println(" Access denied3");if (openServo.read() == 78){openServo.write(166);openPattern == 0;}delay(1000);} else if (openPattern == 1) {openPattern = 2;Serial.println("step 2");if (openServo.read() == 78){openServo.write(166);openPattern == 0;}delay(1000);} else if (openPattern == 2) {openPattern = 0;Serial.println(" Access denied4");if (openServo.read() == 78){openServo.write(166);openPattern == 0;}delay(1000);} }}
