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

In modern days, we must use various high-tech machineries and equipments to get our jobs
done and make the life easier. These machineries should be controlled by the homeowner
from any location as the homeowner might be away from home at workplace or traveling in a
different place in the weekend. Thus a system of remote monitoring and controlling are very
much necessary. Smart home is one of these types of system equipped with home appliances
which we wish to control smartly from anywhere. Some products are commercially available
which al ....etc

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
