Embedded Technology is now in its prime and the wealth ofknowledge available is mind blowing. An embedded systemis a one that has computer hardware with softwareembedded in it as one of its most important components,with a dedicated function within a larger mechanical orelectrical system, often with real-time computingconstraints.

Home automation is one of the major growing industries thatcan change the way people live. Wireless home automaticsystem (WHAS) is to provide those with special needs with asystems that can respond to voice commands and controls theON/OFF status of electrical devices, such as lamps, fans,television etc., in the home.

The uppermost layer is the application layer. In-between, there are other layers which may

comprise components like device drivers andcommunication protocols. A special genre of operatingsystems known as the real-time operating system (RTOS) isusually cater to the deadline-driven requirements of anembedded system.

Touch screen is an electronic visual device. It refers totouching the display on the device with finger or hand.

There are different types of touch screen is there in thisproject capacitive touch screen technology is used. This isfor aged peoples and bed patients they are struggling toget up and switch ON or OFF electrical device. For thesesmall work they need others help while using this projectby touching and giving voice command we can control thehome appliances, without struggling they can do theirwork.

ZIGBEE

Zigbee is a consortium of more than 200 major playersseeking to tap into the potential billion-dollar market ofwireless sensor networks. Zigbee protocol are intendedfor use in embedded applications required low data rateand low power consumption. zigbee’s current focus isdefined as general purpose, inexpensive, self organizedmesh network is used for home automation system.

In another method we can use this zigbee as by fixing thisin the bottom of the apartment . By touching and givingvoice command we can control the home appliances whichis in the 3rd or 4th flour of the apartment. These are thehome appliances which can controlled by zigbee. Such aslamp, fan, television, washing machine etc., in the home.

latest application of embedded system

Samsung is busy now with producing the flexible displaysamsung galaxy s4. we can use this flexibly by folding,bending and curving it. The new technology wouldmean that users can bend the screen concavely orconvexly to adjust the zoom levels.

"The 3D Air-Touch system in mobile devices can offer non-contact finger detection and limited viewpoint foroperating on a floating image, which can be applied to 3Dgames, Because of the small size and portable nature ofmobile devices, implementing a 3D system on thesedevices is different from 3D systems used on TVs and otherlarge screens.

The IoT market is surging and industry leaders predict there willbe more than 15billion nodes by 2015. According to the GSMAlliance, a quarter of these devices will be mobile handsets andpersonal computers. The rest will be autonomous devices thatwill communicate with other machines without user interaction –M2M. M2M communication is on the rise, enabling connecteddevices to exchange and act upon information without humaninvolvement. M2M technology is opening new markets, enablingdevices in our homes, offices and factories to communicate witheach other to provide comfort, convenience and security.

As the technology grows day by day, we can imagine about thefuture in which thing we may occupy every place. The proposedsystem based on Atmel and PIC microcontroller is found to bemore compact, user friendly and less complex, which can readilybe used in order to perform. So, it might be possible forinstance, to have the RTOS, storage areas or other specialsoftware in the cloud and have the embedded applicationsaccess them through internet connectivity. It is always going tobe smaller, faster, and superior in the embedded world!
