Design of LCD and Keypad Interface to PIC Mircocontroller
Interfacing of LCD and Keypad are one of the important interfacing concepts of PIC microcontroller since both the input and output element can form a complete embedded system design. This tutorial is about teaching you how to get input input values from keypad by polling method and display the input into a 16x2 LCD.

Counter using 7 Segment
People / Object counters have a wide variety of applications in Banks, Hospitals, factories etc. This project focuses on building an effective counter using IR as a sensing element and capable of counting from 0 to 999. This project uses Two simple IC's ( IC 555 & IC 4026 ) with IR transmitter and Receiver    to detect the incoming people/object.

This Project comprises of Three parts
  1. IR Transmitter
  2. IR Receiver
  3. 7 Segment drivers
