In this project we will interface a push button switch with PIC16F877A 8-bit microcontroller. If you are new to PIC microcontroller programming we suggest you to execute the basic led blinking project here before trying this project. If you don't have your own hardware for this project, you can schedule this project on our company hardware and access it remotely.

Complete this project and update here to consider it for online course requirements and earn certificate.

The required hardware and software for this project is as below:

A breadboard

A push button switch

Hookup cables

Development board hosting PIC16F877A 8-bit microcontroller

MPLAB IDE from Microchip

PICKIT3 Programmer, connecting cable from PICKIT3 to your computer.

Power supply for the development board

Switch connections

An electrical switch is any device used to interrupt the flow of electrons in a circuit. Switches are essentially binary devices: they are either completely on (“closed”) or completely off (“open”).

PORT B, PIN 5 is connected to one side of the push button switch. An external resistor is connected to VDD(+5V) on one end and to PORT B, PIN 5 on the other end. The +ve end of the led is connected to the PORTA, PA0 pin and -ve end of the led is connected to the ground through a 1K resistor.

Prepare source code, Compiling source code, creating binary
