Experiment with TQFP PIC18F4550 – 44 Pin package, Building and etching custom breakout board. Setting configuring and designing.

Interface single and Multiple IR sensors Module with Arduino Uno and have the result Displayed on a Liquid Cristal Display (LCD). This tutorial covers three chapters explaining step by step starting from interfacing single IR sensor, then Dual and Finally an LCD for displaying the status of the Multiple IR sensor simultaneously. The project is comparatively very easy and serves the basics of sensor interface for various applications.  Find the necessary Circuit, schematic, Source code and Project files on the project page.

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.

A Tutorial for interfacing Stepper Motor with pic18F4550 microcontroller. The Projects shows a simple stepper motor interface with two examples of source code, demonstrating various modes of stepper motor stepping along with detailed logic diagrams and circuitry. The project is posted with necessary schematic, description and project files for download.
