AVOIDENCE DETAILS When the train arrives in a particular direction the transmitter IR senses and generates appropriate signal‚ then at the same time the receiver IR receives the signal and generates an interrupt. When the interrupt is generated the stepper motor rotates in clockwise direction. When the interrupt ends the stepper motor rotates in anti clock wise direction. • Railway Crossing Keywords: Railway gate‚ level crossing. 1.

LCD based voting machine using 8051 microcontroller Electronic voting machine has now replaced the traditional mechanism of voting due to several advantages like security‚ automatic counting etc. This project presents a way to develop an electronic voting machine which displays the count of votes on a 16x2 LCD interface. A user can get his/her vote register through a set of switches (one for each candidate). After every cast of vote‚ the subsequent count can be seen on LCD. The circuit uses AT89C51
