LED BRIGHTNESS CONTROLLING USING SERIAL PORT



Interfacing with pc

Interfacing is done using RS232 DS-9 port which is connected to pc & microcontroller.
On port 3,at p3.0 & p3.1 the input signal is received.
TXD,RXD pins are also used in interfacing.

Sending signals from pc

To send signals from pc we need to make a software using vb .net .This signals will vary from 0 to 255.As per this signals the PWM will vary by duty cycle in microcontroller, resulting in a c ....etc

Introduction

The Parallel Port is the most commonly used port for interfacing home made projects. This port will allow the input of up to 9 bits or the output of 12 bits at any one given time, thus requiring minimal external circuitry to implement many simpler tasks. The port is composed of 4 control lines, 5 status lines and 8 data lines. It's found commonly on the back of your PC as a D-Type 25 Pin female connector. There may also be a D-Type 25 pin male connector. This will be a serial RS-232 port and thu ....etc

Abstract
This paper proposes a novel converter topology that interfaces four power ports: two sources, one bidirectional stor-age port, and one isolated load port. The proposed four-port dc/dc converter is derived by simply adding two switches and two diodes to the traditional half-bridge ....etc
