USB Stepper Motor Driver

USB Stepper Motor Driver, PIC18F4550 USB Stepper Motor Controller

This project shows how to drive and control a Stepper Motor using a USB Interface. It is controlled via USB interface where small software running on the computer can control the stepping sequence of the stepper motor connected over USB. The stepping sequence and delay between the stepping sequence can be controlled easily with software. USB Stepper Motor Driver project is inexpensively easy to make and can be easily modified to run various types of stepper motor. 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.

lm386 amp Audio Amplifier

LM386 IC Audio sound Amplifier home made schematic and circuit diagram

This is simple Audio power Amplifier project that you can make at home easily. We will make this project using a lm386 IC which is a 8 pin IC. You can make it as small as a match box. Due to its tiny size lm386 is perfect for various projects like radio amp, tiny Guitar amp amplifier. lm386 amp is a simple Low voltage Audio power amplifier used in various audio applications. You can find schematics and components required for making this amp here.

Simple Flashing / Blinking LED with a 555 timer Circuit

555 timer IC flashing LED with 555 circuit diagram

If you are looking for a Simple circuit to blink a Light emitting diode without complex circuitry, For some small projects or to  impress your friends maybe then probably small and easy circuits with 555 Timer would be a better option to start with, a Simple Blinking circuit. With help of a Small 555 timer chip you would will be able to that just fine. 555 timer is one of a very low cost and basic IC used now a days. You can make it at very easily here.

USB DC Motor Controller using PIC18F4550

Controlling a DC motor from computer with USB Interface.

This a small project on controlling DC motor with USB pic18f4550 interface board with L293D motor controller for beginners. In robotics and controlling stuffs one of the most basic thing is to control your own applications like DC Motors , Stepper Motors , Servo (with pwm) etc etc,In this tutorial A small application [C#] is controlling pic18f4550 USB interface board with computer, enabling to control my board with keyboard to interface with L293D motor driver.
