ABSTRACT
Here is a microcontroller based wireless equipment controller that can switch on or off upto four devices at a desired time interval set by the user in the transmitter. The devices can be controlled remotely from a distance upto 30 metres from the transmitter. In the transmitter, an LCD module is used to show the device numbers and preset control time for the devices (00 to 99 seconds). The 8-bit AT89C51 microcontroller is the main controlling part of the transmitter section. It is connected to the LCD modu ....etc

STEPPER MOTOR CONTROL USING
89C51 MICRO-CONTROLLER
This controller can control the rotation of a DC stepper
motor in clockwise and anti-clockwise
directions.It has application in machine control and
robotics. the block diagram of the
stepper motor control system has a power supply, microcontroller board, contrl section. Atmel
AT89C51 is a powerful, highly flexible and
cost-effective solution to many embedded
control applications.

I have made the project of wireless equipment control using at89c51 but I am facing the following problems.

1 In the project the 16X2 lcd display is not showing any display even after loading the program in controller. It just shows 16 square boxes on screen instead if showing the display of setting time for four LED.

2 Ideally Pin no 17 of TRX434 should have high logic (5v) to transmit the signal to the receiver . But at pin no 17 I am getting the voltage between 0 to 1 V. ....etc

ppt for automatic street lights control using microcontroller at89c51

Introduction

The main objective of this paper is to provide a better solution to minimize the electrical wastage in operating street lights, in this electronic era human became restless and he is not in a position to regulate the manual operations in any field, a rapid advancement in embedded systems had paved path for the virtual mechanisms based on micro controllers, this paper presents an automatic street light controller using light dependent resistor(LDR) which is also ....etc
