Actually arduino sent " wrong" string. Android program then shows wrong password message.

Actually i set two command, one is "open" and another is "close" and password may contain any digit, later or symbol or combination of them as you like. In the app i used two buttons one for open the door and another for closing the door. When password is given to password box and open button is clicked than app joint the "open" command with the password and sent it to arduino. I add sign with command for that I will separate command and password by using this. After receiving the string from phone arduino program separates command and password from the receive string and save them into two separate variables. Then check the password first, if password matched with saved password then open the door for "open" command, and close the door for "close" command.

Out1 and Out2 of report motor driver is connected to the dc motor of leaser movement mechanism. L293D has two input voltage, one for ic itself and another for motor voltage. I have connected 5V to both pin, our motor will run well. This driver has 4 ground pin, and all are connected to ground. Heat sink is not required here. A 5V regulator ic (LM7805) is used here and its input is connected to the output of an ac adapter.

A.5V to 12v ac to dc adapter will work fine. The output of the adapter is directly connected to arduino vin pin because arduino board has an internal voltage regulator. Tx pin of hc-05 is connected to arduino rx pin, and rx pin of hc-05 is connected to arduino tx parts pin. This may be a bit confusing but the fact is that, the data transmitted by hc-05 is received by arduino ( hc-05 tx to arduino rx and the data transmitted from arduino is received by hc-05 (arduino tx to hc-05 RX). The circuit diagram, Proteus source, breadboard connection diagram, Fritzing sketch all are uploaded herewith. Attachments Step 5: Arduino Program for Bluetooth Control Password Protected door Lock The code for bluetooth control smart door lock is very simple. I have designed android application in such that it sent a command with the password.

Enable pins 1 and 9 (corresponding to the two motors) must be high for motors to start operating. When an enable input is high, the associated driver gets enabled. As a result, the outputs become active and work in phase with their inputs. Similarly, when the enable input is low, that driver is disabled, and their outputs are off and in the high-impedance state. For details of L293D check the datasheet attached herewith or click here. Voltage regulator (LM7805 This is a 5 volt regulator.


Output of ac adapter is given to input of the regulator. Output of the ic is regulated. This output is given to L293D and microcontroller. Pinout and datasheet of the ic is attached. Attachments Step 3: tools and Supplies for Smartphone control door Security. Soldering Iron and Solder if you want to use pcb instead of breadboard. Hot Glue gun. Access to a computer Step 4: Circuit Connection of Arduino and Android Control door Lock circuit connection for our smart door lock is not so complex.

Motor Driver ic (L293d l293D is a dual H-bridge motor driver integrated circuit (IC). Motor drivers act as current amplifiers since they take a low-current control signal and provide a higher-current signal. This higher current signal is used to drive the motors. L293D contains two inbuilt H-bridge driver circuits. In its common mode of operation, two dc motors can be driven simultaneously, both in forward and reverse direction. The motor operations of two motors can be controlled by input logic at revelation pins 2 7 and. Input logic 00 or 11 will stop the corresponding motor. Logic 01 and 10 will rotate it in clockwise and anticlockwise directions, respectively.
