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

Electrically stimulating nerve tissues associated with vision (such as the retina) to help transmit electrical signals with visual information to the brain through intact neural networks. This is the basic concept of the artificial vision system. This idea is rational and feasible, and therefore has sparked R&D throughout the world.
There is more than one specification for the system. Many types of systems are being proposed because of its potential for the development of various types of devices with existing technologies. Such devices take ....etc

A new device to help the blind to see has been developed by scientists. The electric lollipop or BrainPort vision device captures images using a small camera and then turns the image into tiny tingles on the tongue. Tingles are sent to the brain, which then turns the tingles into pictures. After a few days of practicing people, who otherwise could not see, they were able to distinguish shapes, read signs and even read letters. This amazing new device can help people to interact with their environment so never before experiences.

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
