Home Security using GSM, this project secures your home and also creates a log of door activity mean open and close. It has four door sensors and if state of any door changes it will send a text on your cell. you can use these switches as per your requirements for example you can use a break beam detector instead of switch or can use PIR sensors too. So its up to you that what kind of security you need to implement. Here is a view of complete hardware



Here is Circuit Diagram

Though its a bit late.. but its never too late

Rickey's World wishes you a very very Happy New Year.. may this year brings lots and lots of joy and prosperity to your life

Last year has been great for all of us and I wish this year brings more happiness

Once again Happy New Year 2012 from Rickey's world team...!!!

Hi Friends,

I have a great news to share with all of you I hope you all know about Asia's Biggest Magazine Electronics For You. In December 2011 edition of EFY, Rickey's World is featured in the Top 5 useful websites for microcontroller and its really proud moment for us that we are #3

I really want to thank everyone for having faith on us and considering us as best resource We will always make sure we stay the best and improve everyday.

A Closer look:

Many of you should made Thermometer using LM35 and 2*16 LCD its very simple. Nokia 3310 LCD is very handy to use in this kind of applications, it is slim and have a lots of graphical details options, you can make symbols, icons with your display too.
This project will guide you to make a Thermometer using Nokia 3310 LCD, you have to use Library of this LCD which is available on this site to get it click Here, try making different kind of Display Graphics using this Library

This Project uses PIC12F629 and DS18B20, one wire temperature sensor from Maxim IC Reports degrees C with 9 to 12-bit precision, -55C to 125C (+/-0.5C). Each sensor has a unique 64-Bit Serial number etched into it - allows for a huge number of sensors to be used on one data bus.
