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)

Here the another Line Follower robot tutorial… The robot mechanical design not included, you may create the shape and the mechanical design of your line follower robot by your self. Just use motor gearbos which have high torque…

This line follower robot use the following module:

• Proximity sensor: 8 pcs of phototransistors
• Microcontroller: ATMega16
• Motor driver: L298 module
• Programming language: C

Here the complete robotics tutorial based on youtube video. There are 40 long time videos which will explain about robotics. Tired to watching this video online..? Then try to download the video using keepvid.com.
