IR-2110 based squarewave inverter by using 555 Timer
Description of IR-2110 based squarewave inverter by using 555 Timer: An inverter is a device which converts dc voltage to output ac voltage at required voltage and frequency.The output ac voltage frequency can be fixed or varied .The variable frequency output voltage have several applications in conveyor,machine tool testing.This convertion can be done by controlled power on and power off devices like MOSFET and IGBTs.
IR-2110 is a high speed,high voltage power MOSFET and IGBT driver. This inverter converts the dc voltage into ac output voltage of squarewave pulses by using two jk flif flofs.
Dc signal is given to the 555 Timer,it produces squarewave pulses.these squarewave pulses are given to the two JK flif flofs,the two pulses are converted into four signals and are given to the IR-2110.From the inverter the signals are given to the four IGBTs,then the signal is converted to ac signal of required voltage and frequency.

Single Dc Motor Speed Control By Tv Remote
Abstract:– Here is a very simple example of DC motor speed control by changing firing angle of TRIAC with the help of micro controller AT89c52.In order to mange speed variations for the motor we use firing angle by using thyristor. This method is widely used method for speed variations in DC motor systems. In this project we use AT89C52 controller in the place of DIAC for firing TRIAC.A zero crossing detector circuit is used here to interrupt AT89C52 after every 10 ms. After getting an interrupt AT89C52 will fire TRIAC after some delay from 1 to 9 ms. This will reduce the current input to motor and so the motor speed will reduce.By changing the delay time with the TRIAC speed variation can be managed.
Software logic: –The complete operation is based on the software embedded in micro controller P89C51ED2.C is the programming language used in this application. Each function written has different functionality like ext1,ext2 and delay in speed. Programmed code is written on to micro controller.

Energy Saving Systems For Railway Platforms
Energy Saving System For Railway Platforms Projects main idea is to develop a micro controller based project for saving energy for railway platforms.
NEED FOR THE PROJECT: Normally in railway platforms Whether the Train is there or not, Unnecessarily all Lights in the platforms are Glowing. In present system there is lot of usefulness wastage of energy. Maximum energy is wasted at the time of no train on the platform. All the lights televisions etc are not stopped when there is no use.
AIM OF OUR PROJECT
Our project is a computer controlled system Wherein all the train arrival and departure timings are entered in it.
So we can able to switch on all the lights When the train is about to come or to leave. During the other times we can glow Some important lights so that the platform will not be left completely dark.
In this project micro controller application setup is installed at each platform. Using a remote PC we will command micro controller unit for controlling lighting system for each platform.
