Microcontroller Basics
A Microcontroller is a small and low-cost microcomputer, which is designed to perform the specific tasks of embedded systems like displaying microwave’s information, receiving remote signals etc.The general microcontroller consists of the processor, the memory (RAM, ROM, EPROM), Serial ports, peripherals (timers, counters) etc.Types of MicrocontrollersMicrocontrollers are divided into various categories based on memory, architecture, bits and instruction sets. Following is the list of their typesBit − Based on bit configuration, the microcontroller is further divided into three categories.8-bit microcontroller − This type of microcontroller is used to execute arithmetic and logical operations like addition, subtraction, multiplication division, etc. For ...
Read MoreWhat are the different types of LED available?
LEDs (Light emitting diodes) are very widely used in today's electronics equipment and they are ruling the world's display technologies today. LED's are used for much electronic equipment. Mostly they are used as panel indicators on televisions, radios and other domestic electronic and industrial equipment. There are different types of LEDs.Traditional inorganic LEDs − These are used for small LED lamps, panel indicators etc.,High brightness LEDs − These are used for domestic lighting.Organic LEDs − Organic LEDs uses organic materials and are replacing the traditional types of LEDs with increased efficiency.
Read MoreWhat are the career prospects in VFX?
Career prospects in the VFX (Visual Effects) industry are enormous, especially in a country like India which not only has a huge domestic market for VFX-enriched content in its mass media entertainment programs but is also a massive base for VFX job work for the global entertainment industry.The Right SoilIndia has the right eco-system to provide high-quality VFX output at an affordable cost and at scale. VFX requires the animators to be creative, imaginative, skilled in application software and willing to work long hours and at wages that very few other countries can match. So, yes, the opportunities in VFX ...
Read MoreHow will drones help improve the security?
Proper security involves all-around surveillance or observation of people, their behavior and actions, immovable property like land and building as well as movable property stationed there. Surveillance is generally conducted with the help of methods that either have limited mobility or are stationary like, CCTV cameras, GPS tracking dependent on satellite connectivity and not helpful in close observation, stake-outs, which are time-consuming, data-based profiling and biometrics and some other methods.Drone Has Turned the TableAll these methods have their own level of advantages and limitations but when it comes to drone technology, the efficiency, and effectiveness of any security operation increase ...
Read MoreHow does a refrigerator keep the temperature cool inside it?
In ancient times the food was preserved by conventional techniques like salting and pickling which were not helpful all the time. These days refrigerators are utilized to protect food for long periods by cooling it.This cooling procedure keeps bacteria away from attacking and ruining the food, which thus lessens food wastage. The refrigerator is one innovation that has positively changed the way we live. It has made it feasible for everybody to store or preserve food for long periods of time.A Refrigerator functions on 2 basic principles:As a fluid dissipates, it absorbs the warmth from the surrounding ranges.The inverse happens ...
Read MoreWhich Storage drive is better, SSD or HDD?
A great many people now purchase laptops for their processing needs and need to settle on the choice between getting either a Solid State Drive (SSD) or Hard Disk Drive (HDD) as the storage component. So which of the two is the better decision, an SSD or HDD?There's no straightforward response to this question; every buyer has different necessities and we need to evaluate our choice in light of those requirements, your preferences and obviously the cost.Despite the fact that the cost of SSDs has been falling, the cost per gigabyte advantage is still firm with HDDs. However, in the ...
Read MoreWhat is the principle behind wireless charging?
In the present world, technology has got very advanced. Most of our daily tasks have been automated which has made us more reliable on electronic gadgets. Wireless Charging gives an advantageous, safe, and solid approach to charge and power a large number of electrical gadgets at home, in the work, and in industries.By removing the use of physical connectors and links, remote charging makes it efficient and brings cost and safety advantages over the conventional charging wire. From cell phones to hand-held mechanical gadgets and heavy duty gear applications, wireless power keeps them protected, constant and maintains the reliable exchange ...
Read MoreEPC Gen 2 Tag Identification Layer
Tag identification layer of Electronic Product Code (EPC) Gen 2 lays down the method by which the readers can receive the identifiers from the tags. EPC Gen 2 (second generation) RFID (Radio Frequency Identification) network has two main components, tags and readers. RFID tags are affixed on objects with EPC encoded on them for identification. EPC helps to check identities of objects like inventory, assets and people, and track them. Readers are the intelligent part of the system that tracks the tags. The tag identification layer addresses the multiple access problem of getting messages from unknown number of tags.Working PrincipleIn ...
Read MoreWhat is backscatter?
Backscatter is a method that uses an incident radio-frequency (RF) signal to transmit data without a battery or power source. It employs passive reflection and modulation of the incoming RF signal, and converts it into tens or hundreds of microwatts of electricity, that can be encoded for data communications.It differs from other wireless communications since the communication is half duplex in nature, i.e. both the sender and receiver cannot transmit simultaneously. The mains advantage of backscattering is that it’s low energy requirements and low complexity of deployment.Architecture of backscatter communicationsA basic backscatter communication system has two main components: tags, and ...
Read MoreEPC Gen 2 Physical Layer
Physical layer of Electronic Product Code (EPC) Gen 2 defines method of transmission of bits across the network. EPC is a universal identifier encoded on RFID (Radio Frequency Identification) tags to check identities of objects like inventory, assets and people, and track them. The second generation of this technology, as laid down by EPCglobal Tag Data Standard, is called EPC Gen 2.EPC Gen 2 RFID network has two main components, tags and readers. Tags are affixed on objects that enables them to be identified or tracked. Readers are the intelligent part of the system that tracks the tags. The physical ...
