Seven Segment Multiplexing using PIC18F4550 Microcontroller

As explained earlier, a seven segment interfaced with PIC uses almost an entire port (minimum 7 pins) to display a value. But a real time application, like watch, calculator etc., usually requires at least 3-4 seven segments. In such a case it is not advisable to use a port of the controller for each seven segment. In these cases, multiplexing technique is used to work with more than one seve ...

A CARBON NANOTUBE MICROPROCESSOR MATURE ENOUGH TO SAY HELLO

Did you know that researchers are looking for an alternative to silicon? Did you know in principle that Carbon Nanotubes processor could run three times faster while consuming about one-third of the energy of their silicon predecessor? The Engineers at MIT and Analog Devices have created the first fully programmable 16-bit Carbon Nanotube microprocessor. Since Silicon Transistor is no longer shrinking as it ...

How the Semiconductor Changed the World of Business

There are few items that have changed the world as much as the semiconductor. This material has revolutionized many areas of modern life, including the way in which businesses operate and so much so that it is hard to image how businesses managed beforehand without semiconductors. What is a Semiconductor? So, what exactly is a semiconductor? This is a material which has conductivity between conductors and n ...

AJIT – FIRST-EVER “MADE IN INDIA” MICROPROCESSOR DESIGNED BY IIT BOMBAY

In this modern era, the electronics industry is incomplete without microprocessors. From daily household appliances to space exploration – microprocessors are accompanying us everywhere and making lives way easier. But, independently designing and manufacturing a processor is an extremely complicated task and done by only a few countries like the US, Italy, France, Japan, Taiwan, Singapore, Malaysia, etc. I ...

TOOLS FOR THE ELECTRONICS HOBBYIST PART 1- GRAPHICAL COMPONENTS TESTER

When I started to deal with Chinese electronics suppliers from websites like Alibaba, Aliexpress and Taobao, I discovered that there are huge amount of undiscovered tools from the Chinese market. They are not easily discovered, maybe due to the Chinese language barrier, especially when we deal with a Chinese website like Taobao or maybe because most of us are used to deal with known electronics distributors ...

PNP Transistor – How Does It Work?

The PNP transistor is a mystery to many. But it doesn’t have to be. If you want to design circuits with transistors, it’s really worth knowing about this type of transistor. For example: Want to automatically turn on a light when it gets dark? The PNP transistor will make this easy for you. In my article how transistors work, I explained how a standard NPN transistor works. If you haven’t already, I’d reall ...

Surrounding Gate Transistors – Price + Size + Performance

Intel co-founder Gordon Moore predicted in 1965 that the number of transistors per silicon chip would double every two years. This came to be known as Moore´s Law which has been proven accurate for the last fifty years. Many scientists argue that the law is soon to be broken because of physical limitations. The end of Moore´s law would mean a stagnation in computer processing and power and could cause econo ...
