This project demonstrates interfacing a 16x2 alphanumeric LCD with a PIC16F877A microcontroller using 8-bit parallel communication. The LCD displays the text: Line 1: EMBEDDED Line 2: SYSTEMS This project helps you understand how to send commands and data to the LCD using control signals (RS, RW, EN).

This project demonstrates using the external interrupt (INT) of the PIC16F877A. When a push button connected to RB0 is pressed, an interrupt is triggered, toggling an LED or output connected to RC0.

This project demonstrates two-digit number display (98) using 7-segment multiplexing with the PIC16F877A microcontroller. Multiplexing allows multiple 7-segment displays to share the same segment lines, saving I/O pins and reducing hardware complexity.

This project demonstrates a simple LED blinking example using the PIC16F877A microcontroller. The LED connected to PORTB Pin 7 (RB7) toggles ON and OFF every 1 second, illustrating basic digital output control.

This project demonstrates how to interface a 16x2 LCD with the PIC16F877A microcontroller in 4-bit mode. It displays two messages on the LCD: "EMBEDDED" on the first line and "SYSTEMS" on the second line.

This project demonstrates interfacing a 4x3 matrix keypad with a PIC16F877A microcontroller and displaying pressed keys on a 16x2 LCD.

This project demonstrates controlling a relay using a PIC16F877A microcontroller. A push button connected to RB0 acts as the input. When pressed, the relay connected to RB1 is turned ON; when released, the relay turns OFF.

This project demonstrates **Timer0 interrupt** in the PIC16F877A microcontroller. The LED connected to RB0 toggles ON and OFF based on timer overflow events.

This project demonstrates how to interface a 7-segment display with a PIC16F877A microcontroller. The display counts 0 to 9 with a 1-second delay between each digit, showing how segment encoding and port control work in embedded systems.

This project demonstrates how to control 8 LEDs simultaneously using PORTB of the PIC16F877A microcontroller. All 8 LEDs are turned ON for 1 second and then OFF for 1 second — a simple but essential step in learning digital output control.
