NodeMCU - (MCU = stands for MicroController Unit(which really means it is a computer on a single chip)) NodeMCU is an open source platform based on ESP8266 which can connect objects and let data transfer using the WiFi protocol.  NodeMCU is an open source firmware and development kit that helps you to prototype or build IOT products. The NodeMCU development board can be easily programmed using the Arduino IDE Microcontroller - ESP-8266 32 bit clock speed = 80 Mhz operating voltage = 3.3 volts input voltage = 4.5 - 10 volts FlashRAM(SRAM) - 4MB/64Kb Digital i/o pins - 11 Analog i/o pin - 1 ADC Range - 0 - 3.3 volts Application Prototyping of IoT devices Low power battery operated applications Network Projects Project Requiring multiple i/o interfaces with wifi module and bluetooth facilities

Arduino is an open source hardware and software company, project and user community that designs and manufactures single-board microcontroller and mocrocontroller kits for building digital devices. Arduino is an open-source platform used for building electronics project. The boards are equipped with sets of digital and analog input/output pins.

Logic Gates are the basic building blocks of any digital system. it is an electronic circuit having one or more than one input and only one output.  AND Gates A circuit which performs an AND operation. OR Gates A circuit which performs an OR operation. NOT Gate NOT Gate is also known as Inverter. NAND Gate A NOT-AND operation is known as NAND operation. NOR Gate A NOT-OR operation is known as NOR operation. XOR Gate XOR or Ex-OR gate is a special type of gate. it can be used in the half adder, full adder and subtractor. XNOR Gate XNOR gate is a special type of gate. it can be used in the half adder, full adder and subtractor.

                            ideal diode Ideal diode is two terminal which acts as perfect insulator when reverse biased and acts perfect conductor when forward biased. Characteristic  1. When ideal diode is forward biased. it acts as perfect conductor with zero resistance and zero voltage drop across it. When forward bias voltage increases the depletion layer width is also decrease and due to decrease in depletion layer the resistance across the diodes in forward bias condition decreases. 2. When ideal diode is reversed biased it acts as perfect insulator with infinite resistance and zero current through it. When reverse bias voltage across the diode increases the depletion layer width is increases and due to increase in depletion layer width the resistance in reverse bias condition across the diode increases. 3. Thus  Ideal diode acts as automatic switch. 4. which is closed in forward bias(i.e. acts as a cl...

The brain of computer is the microprocessors that you generally known it as CPU(Central Processing Unit).  The first microprocessor that was made is 8085. which has very few basic functionality. All the arithmetic and logical task performed by these processors. Today's microprocessor has millions of transistors. That helps them to works so fast and efficient. Intel is one of leading company in this field.

Electronic and communication  engineerin g Let talk about detail knowledge about electronic and communication engineering. This is basically focus on studying about different types of electronic devices and electronic equipments. Which can communicate with different types electronic devices through network and share information and ideas.  How electronic devices connected. Communication - it has basically three main parts - Transmitter, Channel and Receivers. 1. Transmitter where input takes and convert the physical message into electrical signal and then converted into analog signal or digital signal. 2 Channel - in this section now signal can transfer from one place to another place via channel like (wireless)air, water and wired( coaxial cables, optical fibres). 3. Receiver - here after signals traveling through channel it reaches on the side of receiver and then from that analog or digital signal we convert into it in electrical signal then using transducer electrical sign...

How do I choose the branch of engineering for myself? when a student wanted to pursue a engineering career. There are various points before choosing a definite branch. Because engineering is broad field to learn how technology work. what excites you to learn more that decides which branch is perfect for your career. because if you cannot choose a perfect branch in engineering then it should be very difficult to survive four years of journey.  1. Never choose any branch on the basis of highest salary or demand. Because each engineering field has maximum opportunities that you can grab and make a successful career.  2. In today's world Demand of quality Engineer are increasing not a tag of engineering. So, never do wrong decision for your career. 3. Contact with different friends, families or relatives who are pursuing engineering in that particular area where you want to interested to take admission. 4. You can also visit different types of website and read a lot of contents ...

                      Sustainable energy There are various types of energy which is most important for our life. but when we are talking about sustainable energy this means that which is eco-freindly and available for long duration. like solar energy, water energy, wind energy. Many developing countries are now working to maximise the production amount of sustainable energy which is beneficial for the public health and natural earth.

Renewable sources of Energy Solar energy is now one of the best resource of energy. Because it comes in the category of Renewable sources of Energy. it is eco-freindly. And, it is available for free anywhere in the world. Today governments are continuously working to reduce the carbon emissions of each state. So that we live in a village or city with pollution free. Thare are many houses which set up a solar panels on their roof and save his money. Because, Continuous and huge demand of electricity causes the increment in electricity bills. Solar energy is the cheapest source of energy. Most of the countries are continously setting the big plants of solar panel to fulfill the huge demand of electricity. Today we are using solar energy for cooking food by using solar cookers and water heating. 

                      VIRTUAL REALITY VR is a computer generated simulation or replacement of real environment. and feel the virtual world substitute of digital world.its mental teleportation. its all starting from sensorma which is a revolutionary motion picture system that takes you to the another world.  with 3d display and vibrating sit  the viewer have 3d view of streets and feeling the vibration of motorcycle and fan are also attached that blow air on your body and also experiencing the smell of the city. this idea is very intersting and attracting the attention of many people. in 1968, The famous MIT computer scientist ivan sutherlandis being the godfather of VR display. he created the first vr head set with his colleagues has started the first virtual headset experiment.  he also created a sketch pad in 1963 in 1987, the actual term virtual reality being coined, And defining the virtual reality virtual means b...

how to get dream job? generally we have more dreams to fulfill so we are starting our career as a emlpoyes.  Part time and Full time If you want to get jobs in your life with us we will help you to find very good job that help you to get achievements in your life.
