Latest How To

In today’s age of connectivity, smartphones and tablets are becoming more of a necessity rather than a luxury. Whether it is not to miss important mails, being updated with the news or finding directions when lost – connecting to the Internet anytime and anywhere is becoming an integral part of our lives. It’s now possible to get internet access in any location as long as your phone gets a good signal from the cellular network.

You can also use public Wi-Fi hotspots to connect to the Internet through a shared connection. So how exactly does the Internet, which was made for computers, work on your mobile phone?

First, let’s see what Mobile Internet is. In simple terms, Mobile Internet is a smaller Internet scaled down to fit the dimensions of a web browser on a mobile phone. The mobile phone network is an example of a cellular network.


As we see the above procedure for developing as wired mouse for a purpose. The positive and the negative terminals are the output terminals. Then we see at the other end of the mouse orange and white are to be joined as we have no use of those, then we see to connect green and blue wire for negative and positive of the battery.

Then here is the concept “when we apply the infrared radiation from the TV remote to the bottom of mouse (i.e. at bottom of the chip)  the output terminals go high about 1.5-2 volts for 1.5 seconds then clearly we find it as a trigger (oneshot)” then we can use this for the various purposes. For the counter, i.e. the remote IR LED is fixed in the axis of IC chip then o/p is connected in the place of the clock for serial reload counter.


Mouse is one of the most important peripheral for computers, especially for those which are not touch screen based. Fascinating is the concept that how various types of computer mice are available depending on the need, shape, pointing technology etc. There was a time when only ball mouse was prevalent. A proper surface was needed to make it work and regular cleaning was mandatory too. Then came in the optical technology giving us LED and laser based mice which, now has removed the barriers of wiring too. These optical mice are now the present and probably future of this palm sized computer peripheral. This article would detail with difference between a general optical mouse and its sub-type, a Laser mouse. Obviously, both these mice are based on light based tracking method but stand apart when detailed in numerous other terms.
