If we use the 8th row of the matrix for the character display, then their will be no room for cursor. Normally we display a character in 5x7 matrix and left the 8th row for the cursor. You can not display character greater than 5x8 dimension matrix. Where 5 represents number of coulombs and 7/8 represent number of rows. On a character lcd a character is generated in a matrix of 5x8 or 5x7. Like if the lcd is denoted by 16x2 it means it has 16 coulombs and 2 rows. M denotes number of coulombs and n represents number of rows. All character lcd's performs the same functions(display characters numbers special characters, ascii characters etc).Their programming is also the same and they all have the same 14 pins (0-13) or 16 pins (0 to 15). Many multinational companies like Philips, Hitachi, Panasonic make their own custom type of character lcd's to be used in their products. In both situations, the scanning system will go back to the corresponding result, success otherwise crash.ДЇingerprint Sensor Interfacing using ArduinoД¬haracter lcd's come in many sizes 8x1, 8x2, 10x2, 16x1, 16x2, 16x4, 20x2, 20x4, 24x2, 30x2, 32x2, 40x2 etc. Similarly, for 1: N matching, the scanning system will look for the complete finger records for the finger matching. For 1:1 fingerprint matching, the system will evaluate the exits finger with a precise pattern which is selected within the module. When matching, a user places the finger using an optical sensor then the system will produce a pattern of the finger & compares it with the finger library templates. So that the system will check the finger images to process as well as to generate a pattern of the finger and it will be stored. In fingerprint enrolling, every user requires to place the finger twice. The fingerprint processing mainly includes two elements namely enrollment and matching. The working principle of the fingerprint sensor mainly depends on the processing.

The capabilities of image processing are good, and can effectively capture pictures up to 500 dpi resolution.

Optical technology which is used is professional, and exact module developed techniques.

Power use is low, excellent performance, small in size, and less cost.

The fingerprint reader can perform lesser growth and can be fixed into a range of end products.

It includes image collection as well as chip algorithm.

The features of this sensor include the following.

However the conventional Attendance system without involving IoT can also be built by following the link and Fingerprint sensor can be further used for many other biometric applications like Voting Machine, Security system etc. This information can then be displayed in the dashboard of ThingsBoard making it available for the required authorities to view and analysis information over the internet without having any direct physical access to the hardware. Here, we will build a biometric attendance system using Arduino that scans for finger print and on successful identification of the person it will log the information to a cloud platform like ThingsBoard by using the ESP8266 Wi-Fi module.

Most conventional attendance systems available today store the information over a micro SD card and have to be connected to software via a computer to access the information. In this project our aim is to leverage this IoT into the boring attendance system to make it smart and more effective. Primarily, fingerprints and iris images are considered to be the most reliable for use in biometric systems. With the recent development of various cloud based computing and storage systems, data can be securely stored and retrieved whenever required. The process of manually taking and maintaining the attendance records becomes highly cumbersome Biometric systems have reached a sufficiently advanced stage wherein they can now be deployed in systems without hampering portability. The most common means of taking attendance in the classroom is by calling out the roll numbers of students or asking the students to manually sign the attendance sheet, which is passed around during the lecture.

But today with the advent of IoT, Smart cities etc the idea no longer sounds strange, we have devices around us that have become smarter by being able to communicate with the internet.ДЄttendance plays a major role in educational institutions. Few years back if you were to tell someone that the Geyser and bedroom lights in your home are connected to the internet, they would be baffled and might even criticize it as over-engineered products.
