Capacitors, an Introduction

Capacitors are two terminal electronic component used to store energy in form of electrostatic field. They are one of the most commonly used components. Among the many uses, some are :- Providing a bypass path for noise Smoothing voltage of power supply Blocking DC current (allowing only AC current to flow) Read more about capacitors.  

Introduction to AVR Microcontrollers

Just what is a microcontroller? To get you understand quickly I define a microcontroller as a single chip computer. Yes it is a full blown computer in its own. It has a C.P.U., RAM, some amount of EEPROM (for secondary storage i.e. permanent storage without power), many on-chip peripherals(Timer,Serial communication, Analogue to Digital converters etc.). If you don’t understand, no problem I will be dealing them in detail in next tutorials. But compared to a P.C. their resources(RAM,speed etc)are less. But that is what is required ! Because P.C. is a general purpose computer, which means it can run thousands of different software that are available for specific needs. Like it can run a game. The same P.C. can run this browser in which you are reading this! It can run a custom solution for banks,railways and airways. It can run a 3D modeling, video editing & image editing software for a production company. Many of these are huge software,requiring lots of memory and CPU power. And a P.C. can run simultaneously many of these ! So to run them the host computer should have enough RAM and CPU power so that it can run heaviest of them. But in case of a microcontroller(aka MCU) which is used for a specific purpose like switching a Microwave oven heating off after […]
