4 Wheeled Robot Design Basics and Challenges

4 Wheel Drive Robot Differential Steering Design challenges and chassis designing

4 Wheel Robot Design: This article deals with some of the design oriented challenges that come in the way of designing a 4 Wheel Robot that uses Differential Steering for taking turns (left and right) or to make a Complete 360 Degree in-place (pivot) rotation (zero-radius turning). Attention to some basic details can help a beginner to make an efficient robot without loss of much energy and torque.

The project is posted with necessary schematic, description and project files.

Infrared IR Sensor Interface with PIC18F4550 Microcontroller

IR Sensor Interface with PIC18F4550 Microcontroller project - Digital Input

This project demonstrates simple IR sensor Circuit Module interface to a pic18f4550 microcontroller to blink few leds. This project also shows how to take digital input from a pic18f4550 by setting few pins digital hence reading the sensor value as 0 and 1. This is very simple, easy, low cost and inexpensive to make, the IR sensor can be simply replaced by push switches. The source code can be easily modified for various other related microcontroller projects, Find the Digital input Source code, schematics and necessary project files which is coded with Mplab IDE C18 compiler. Mplab X IDE version project also included.

PIC18F4550 Tutorial: Blink LED - 2

PIC18F4550 Programming Tutorial , chapter 4 and method 1 for programming

Chapter4: Blink an led using PIC18F4550, Method 2 Header files
This is another tutorial for programming a PIC18F4550 Microcontroller, blinking a simple LED using header files.
My previous tutorial explained about programming pic18f4550 in a direct approach, however this tutorial focuses on the usability of the header files. This article projects another methodology of  pic18f4550 programming. A usual way of coding everything in one file may lead to confusion and it is sometimes hard to check for errors, specially while handling complex coding, hence diving the code in various header files has its advantage. This tutorial explains how to create and use User defined header files with sample code and project. Also it lists some benefits for adapting to such kind of programming habits with a simple example of blinking an led with source code.

PIC18F4550 Tutorial: Blinking an LED

How to blink an led using pic18f4550, Method-1, This article is the third chapter for  learning various methodologies of programming a pic18f4550. Here we will discuss the various blocks of coding and alternatives while programming a pic18f4550.

This simple example of blinking an led is intended to explain few basics things that need to be taken into consideration while  programming a pic18f4550. I have also provided the sample coding with proper description for both mplab ide and mplabx ide.

L293D Motor Driver IC

L293D Motor Driver IC controller working and description with pin configuration

L293D Motor Driver IC

L293D, is a Motor Driver IC which allows the motor to drive on either direction. L293D is a 16-pin IC which can control a set of two DC motors simultaneously in any direction. It means that you can control two DC motor with a single L293D IC.The l293d can drive small and quiet big motors as well, Check the Voltage Specification at the end of this page for more info along with a sample project and L293D IC Logic Description.
