This PIC16F877A tutorial document was written Lukas Hoffmann. This tutorial containing the explanation about microcontroller PIC16F877A and the sample code using C/C++ programming language.

There are some simple interesting project in this tutorial such as how to make blinking LED, how to display message on computer screen, how to drive DC motor and Servo motor, how to manage input sensor (photoresistor, sonar sensor, IR sensor etc)

Before read the rest article/tutorial, please watch the video first.. . See the robot’s movement and i’t speed. This is very great…!

You may see the video here.

This line follower robot is very small and simple. This robot is running fast and follow the line very smoothly.

C Programming for Microcontrollers – Featuring ATMEL’s AVR Butterfly and the free WinAVR Compiler

Introduction

C Programming and microcontrollers are two big topics, practically continental in size, and like continents, are easy to get lost in. Combining the two is a little like traipsing from Alaska to Tierra del Fuego. Chances are you’ll get totally lost and if the natives don’t eat you, your infected blisters will make you want to sit and pout. I’ve been down this road so much that I probably have my own personal rut etched in the metaphorical soil, and I can point to all the sharp rocks I’ve stepped on, all the branches that have whacked me in the face, and the bushes from which the predators leapt. If you get the image of a raggedy bum stumbling through the jungle, you’ve got me right. Consider this book a combination roadmap, guidebook, and emergency first aid kit for your journey into this fascinating, but sometimes dangerous world.

I highly recommend that you get the book, ‘The C Programming Language – second edition’ by Kernighan and Ritchie, here after referred to as K&R. Dennis Ritchie, Figure 1, wrote C, and his book is the definitive source on all things C.
