Fingerprint recognition lock

This was the project's final week, and as previously mentioned in the blog, the product's basic functionality is now accessible. As a result, the team's key tasks this week were as follows: 1- All of the circuits have been completed, and all of the components have been fitted together on a wooden plank to portray the project as a whole. 2- By inserting the correct and incorrect fingers, the project can be tested with the code and library. figure 4: Final circuit 3- All the team members started working on the poster, presentation, and final report which will be submitted the week after the bench inspection day. The project is done at this point, the team is now preparing for the inspection day and the completion of all the required forms.

 The team accomplished the following tasks during this week of the project: The fingerprint sensor system's code was modified to allow it to function as a whole. Prompts were established on the LCD screen such as 'place finger', which appears on the screen after the software is submitted to Arduino. When the right fingerprint or password is registered, the screen displays "recognised", whereas when the incorrect password or fingerprint is inputted, the screen displays "error," and after a second's pause, returns to the input interface. Figure 3: door lock and relay  In figure 3, it shows the connection part of the circuit which includes the solenoid lock that needed 12V at least to work, the relay module was linked with the AC adapter wire. The tasks for next week: The group will test the system next week and build the system's flooring.

The team primarily performed the following tasks during the third week of the project: 1-The circuit was set up with a working LCD screen code which worked with the fingerprint sensor. 2- The power issue with the battery and the relay module has been fixed and the circuit was linked to the lock. Figure2: fingerprint sensor 3- A breadboard was required in this case because there weren't enough pins to use in the circuit. In figure 2, male to male wires connected with the breadboard and then to the Arduino. Tasks for next week: - Connecting the relay module, lock, and power supply to the Arduino - Setting up the buzzers and led lights to the circuit.

 During this week, the team discussed the process of the project. 1- At the start of the setup, The components were gathered and their functionality was individually checked to ensure everything will work. 2- The team ran into an issue where the voltage input from the battery source was too low for the lock to function, therefore the extra supplies were requested from the EEE workshop. The components including an AC adapter to increase the input voltage and a buzzer to add an extra function to the circuit.   AC adapter   Buzzer       3-More research was conducted to make the LCD screen work with the circuit 4- The team found it difficult to write the LCD code as the code did not run as needed. Figure1: installing the LCD screen and buzzer into the system figure 2: LCD code problem Tasks for next week: - The team will try to implement a suitable code to get the LCD screen to run. - Figure out how the connect it to the outputs of the fin

The team focused on completing the following tasks within the first week of the project:   1-The team discussed the materials required for the project. 2- The discussion included an action plan for the coming weeks, and deadlines set by the team leader to ensure finishing the project on time; ensuring constant communication between the team members. 4- The team ran into a problem where there was a shortage of certain supplies that needed to be brought in from the EEE. For example, resistors, AC adapter and LED lights. The items listed below are needed for this project:   Arduini Uno   Relay module         Door lock     Fingerprint sensor  LCD Screen 16x2          Potentiometer            LED lights 100 Ohms resistors       Male to male wires.
