RFID Based Attendance System Circuit Working Source Code

RFID Based Attendance System – Circuit, Working, Source Code

Attendance in colleges is generally paper based which may sometimes cause errors. Taking attendance manually consumes more time. So the proposed attendance system uses RFID technology to take attendance. In this system, each student is issued an RFID tag. Controlling unit is in the institute. Whenever the card is placed near the reader, it will …

PIC16F84A using seven segment display

How to implement free running counter in PIC16F84A using seven segment display

This post provides the implementation of free running counter ( using c language ) for PIC16F84A micro-controller. This code is written in such a way that, the counter starts from a value of ‘0’ ( displayed on the seven segment ) and then increments this value after every second. So, the seven segment display starts …
