I am an electronic engineer (dipIETE ), hobbyist, inventor, schematic/PCB designer, manufacturer. Once the password is changed, the next time we activate the alarm, we will only be able to stop the alarm by entering the new password. This write-up is, Often an analog 0-5V or 0-10V input voltage may need to be remolded to a 0-100% pulse width, I accidentally bought a comparatively cheap turbidity sensor AZDM01. So if the alarm is not activated, on the LCD we will have the home screen of the program which offers two options, A for activating the alarm and B for changing the password.

I dont know what the problem is. I got this error when i tried to verify the codes. This device can be useful if you want to be secure and don't want anyone to come to your room or home. With this configuration you might lack digital pins if using UNO, but in case you use I2C driven LCD or different keyboard you could have enough pins at the Arduino. Pls. You can take a look at them and make your own combination. You can do that via adapter, 9 12V if powered through the Arduino board power jack, or 5V adapter if powered directly to the 5+ pin of the Arduino. The preset password is 1234 but we also have the possibility to change it. A LCD is used for displaying helpful informative, warning and error messages, A potentiometer is used for adjusting the contrast of the LCD, The LCD is driven only with 2-wires by using a resistor, a diode and a shift register, A decoupling capacitor is used with the shift register to prevent gibberish characters in LCD, A piezo buzzer is used for notifying the users when a possible threat is recognized, A loud security siren is used which is driven by a relay module, The system is enabled / disabled with RFID cards, A RFID reader is used for reading the RFID cards, The RFID reader is connected in hardware serial, A switch exists for connecting / disconnecting the hardware serial with the RFID reader, Appropriate design patterns are used in software to reduce memory usage of global variables, A PIR sensor is used for detecting possible motion, A magnetic door switch is used for detecting possible violation, The system can support also 5 more security zones (for example 5 more magnetic door switches), A GSM shield with a SIM card is used for sending SMSs and making missed voice calls, The GSM shield is driven by using a well-written custom library based on SoftwareSerial, All messages which are printed in the LCD are stored in flash memory, A microSD shield is used for storing the RFIDs, the mobile numbers and the SMS text, The main logic of the system is controlled in the software with a finite state machine, You can add / remove RFIDs, mobile numbers or change the SMS text without software changes, The PIR sensor is calibrated at boot time, All users (mobile numbers) are notified 3 times with a SMS message and a missed voice call, One line in loop function due to elegant code! 8.
