Interfacing Fingerprint Sensor with PIC Microcontroller EMBEDDED By Saddam   Sep 11, 2018 5 Interfacing Fingerprint Sensor with PIC Microcontroller Finger Print Sensor,  which we used to see in Sci-Fi movies a few years back, is now become very common to verify the identity of a person for various purposes. In present time we can see fingerprint-based systems everywhere in our daily life like for attendance in offices, employee verification in banks, for cash withdrawal or deposits in ATMs, for identity verification in government offices etc. We have already  interfaced it with Arduino  and  with Raspberry Pi , today we are going to  interface Finger Print Sensor with PIC microcontroller . Using this  PIC microcontroller  PIC16f877A Finger Print System, we can enroll new fingerprints in the system and can delete the already fed fingerprints. Complete working of the system has been shown in the  Video  given at the end of article.   Required Components PIC

Thermal Printer interfacing with PIC16F877A EMBEDDED By Sourav Gupta   Sep 19, 2018 0 Thermal Printer interfacing with PIC16F877A Thermal printer  is often referred as receipt printer. It is widely used in restaurants, ATM, shops and many other places where receipts or bill is required. It is a cost-effective solution and very handy to use from the user’s side as well as from the developer’s side. A thermal printer uses a special printing process which uses thermochromic paper or thermal paper for printing. The printer head is heated at a certain temperature that when the thermal paper passes from the print head, the paper coating turns black in the areas where the printer head is heated. In this tutorial, we will  interface a thermal printer CSN A1 with widely used PIC microcontroller PIC16F877A . Here in this project, a thermal printer is connected across PIC16F877A and a tactile switch is used to start the printing. A notification LED is also used to notif
