ARDUINO UNO RFID WINDOWS 10 UNLOCK

Introduction: ARDUINO UNO RFID WINDOWS 10 UNLOCK

Unlocking windows 10 pass or pin protected with the help of arduino and a RFID card.

The idea around this DIY project is simple. We need a HID capable device, a RFID card and reader. When the arduino reads the RFID card, and the id is the same with the one we entered , it presses the correct combination of the keystrokes ( password) and then presses enter.

#include
#include #define SS_PIN 10 #define RST_PIN 9 MFRC522 mfrc522(SS_PIN, RST_PIN); // Create MFRC522 instance.

uint8_t buf[8] = { 0 }; /* Keyboard report buffer */

int cardCount = 0; void setup() { Serial.begin(9600); randomSeed(analogRead(0)); delay(200); SPI.begin(); // Initiate SPI bus mfrc522.PCD_Init(); // Initiate MFRC522

} void loop(){ // Look for new cards if ( ! mfrc522.PICC_IsNewCardPresent()) { return; } // Select one of the cards if ( ! mfrc522.PICC_ReadCardSerial()) { return; } //Show UID on serial monitor String content= ""; byte letter; for (byte i = 0; i < mfrc522.uid.size; i++) { content.concat(String(mfrc522.uid.uidByte[i] < 0x10 ? " 0" : " ")); content.concat(String(mfrc522.uid.uidByte[i], HEX)); } content.toUpperCase(); if (content.substring(1) == "10 4B 58 7E" , "30 F1 CA 80") //change here the UID of the card/cards that you want to give access { delay(50);

delay(100);

buf[0] = 0; buf[2] = 0x26; // letter 9 Serial.write(buf, 8); releaseKey();

delay(200);

buf[0] = 0; buf[2] = 0x28; // letter Enter Serial.write(buf, 8); releaseKey();

delay(900);

cardCount++; } else { return; }

if(cardCount= 1 ){ delay(50);

buf[0] = 0; // Win buf[2] = 0x28; // letter enter Serial.write(buf, 8); releaseKey();

delay(50);

buf[0] = 0; buf[2] = 0x52; // letter Up Serial.write(buf, 8); releaseKey();

delay(50);

buf[0] = 0; buf[2] = 0x52; // letter Up Serial.write(buf, 8); releaseKey();

delay(50);

buf[0] = 0; buf[2] = 0x28; // letter Enter Serial.write(buf, 8); releaseKey();

delay(50);

buf[0] = 0; buf[2] = 0x28; // letter Enter Serial.write(buf, 8); releaseKey();

cardCount--; } }

void releaseKey() { buf[0] = 0; buf[2] = 0; Serial.write(buf, 8); // Release key }

Step 3: ( Details)

Change this part of the code to the keys you want to be pressed.

copy and paste the code as many times you want. check the map of the cosponsoring codes for each key. you can find it here.

buf[0] = 0; buf[2] = 0x26; // letter 9 Serial.write(buf, 8); releaseKey();

delay(200);

Change the id to the id of the card, ring or thing you want to use

content.toUpperCase(); if (content.substring(1) == "10 4B 58 7E" , "30 F1 CA 80") //change here the UID of the card/cards that you want to give access { delay(50);

Step 4: Covert Serial to Keyboard

Connect the 2 pins as seen in the image for 1 sec

Fire up Flip 3.4.7
File -> open the USBKeyboard-master\firmware\Arduino-keyboard-0.3.hexDevice -> select -> Atmega16u2 ( or your chip)Settings -> communication -> usbRun

Step 5: DONE

Reboot and test

Unplug and plug Arduino usbTest to txt file or lock the pc (win key + l)Enjoy
