Anti-theft Alarm


      Anti-Theft Alarm Using 555 IC

This is an simple project to prevent the object from thefting. Let us discuss this project below.


 Components Required
   1.     555 IC
2.     10K ohm resistor
3.     10uf capacitor
4.     LED
5.     BreadBoard
6.     Connecting Wires
7.     9v Battery

Circuit Diagram


 Procedure    
· Insert the 555 IC in the breadboard and then connect resistors and capacitor shown in figure

 · Then insert an single piece wire at the 8th terminal of 555 IC

 · Then insert the another single piece wire at the 1st terminal of the 555 IC

 · Next connect an LED to the 3rd pin of the 555 IC and connect another end of Led to ground

 · Now, connect it to the power supply. When the 8th and 1st pin have been shot circuited with the wire the Led doesn’t glows


· When it’s not shoted it glows and we can connect it to the buzzer and use it as antitheft alarm.

 Note: When 8th and 1st pin shoted the power goes directly positive to negative orelse it goes another way so the led glows.

What if you could control the Internet

At present situation internet is the basic need for us, we are using the internet for many purposes from medicine to aerospace internet is used and helps in day to day life activates. Internet is spread out in all the areas and we could say it is the most powerful tool in the world, if you got a chance to control the internet what will you do.                                                Image Credit : Internet In general, more than 5 billion google searches are done all over the world and millions of hours videos are watches in facebook and YouTube daily. What if you got a chance to control the internet, whether it is possible to control the internet, the internet is actually controlled with the help of 7 keys and by 14 peoples all around the world. They maintain the DNS which helps in accessing the internet all around the world. The DNS helps in accessing ...

ARDUINO KEYPAD LOCK SECURITY SYSTEM WITH SERVO MOTOR

                    ARDUINO KEYPAD LOCK SECURITY SYSTEM WITH SERVO MOTOR ARDUINO:          Arduino is Basic system which is used for the controlling various system that does lots of work.The arduino develope in 2003,the arduino is basically a microcontroling unit the code return in the form 8 bit ,32 bit which is return in the language of C and C++`The RAM in arduino is SRAM. KEYPAD LOCK:                       A Keypad Lock is the microcontrolled Security System in which it can be controlled which is contolled by the keypad which is 4*4 matrix and we could be secured with that.Here is the simple project with that we can do the keypad security system.

Creating Artificial Planet

Already our Earth is loosing the habitable tendency due to the deforestation, Climate changes, etc. These all causes our Earth as inhabitable planet, for life better we should move into another planet to move into another planet we could create our own planet. But, it is possible to build a planet as like Earth with Atmosphere, Air, Water, Moderate Temperature, Gravity, etc. Theoretically, it is said we could build a planet like Earth. We could build our own planet right in our solar system for constant temperature as we get in our planet “Earth”. We could probably use asteroids in our solar system to build our artificial planet, but we are having only lower amount of asteroids in our solar system so we cannot build a planet as we expected so we are going to use OORT CLOUD to build our Artificial Planet but problem with this OORT CLOUD is it is so far from our Earth, we haven’t still invented that fast vehicle to bring that materials here, so this case could not help us. We have ...
