In this article we’ll investigate the importance of JSON and why we should use it in our applications. We’ll see that jQuery has got us covered with a very nice convenience function.Details
ইন্টারনেটের নিষিদ্ধ জগত থেকে শিশুদের নিরাপদ দূরত্বে রাখতে বাসায় রাউটারের অনিরাপদ ওয়েবসাইটগুলো বন্ধ রাখা প্রয়োজন।এমনকি অফিসেও অনেক সময় নিদিষ্ট কিছু ওয়েবসাইট ব্লক করার প্রয়োজন হয়। এ জন্য রাউটারে রয়েছে ওয়েবসাইট ব্লকের বিশেষ সুবিধা। কয়েক ক্লিকে তা করে নেওয়া যায়।Details
A buck converter is a voltage step down and current step up converter.The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat.Details
In this post, we will discuss all the theoretical concepts that you need to know regarding I2C before programming/testing it on real devices. As the name suggests, Inter-IC (or the Inter-Integrated Circuit), often shortened as I2C(pronounced eye-two-see), I2C (pronounced eye-squared-see), or IIC, was developed as a communication protocol to interact between different ICs on a motherboard, a simple internal bus system.Details
Would you believe that each one of you is using at least 20 microcontrollers in your house??!! Well, that’s a fact. There are more than two billion microcontrollers being produced every year.Details
How many times have you seen a wire splice where the wires are sloppily twisted together and insulated with electrical tape, or worse, yet, masking tape?? A Plague Upon such slipshod methods! Don’t even go there. Such practices will only result in heartache down the road.
Resistors can be connected in series connection alone or in parallel connection alone. Some resistor circuits are made from combination of series and parallel networks to develop more complex circuits. These circuits are generally known as Mixed Resistor Circuits.
Consider a task of moving a charge from A to B in a uniform electric field. Let this movement be against to the electric field. Some work will be done by an external force on this charge and this work will change the potential energy to a higher value.Details
Capacitor is one of the passive components and it stores energy in the form of electrical charge. Capacitor charges and discharges the charge depending on the circuit operation. It is used mainly in electronic and electrical circuits to perform different tasks, such as smoothing, filtering, bypassing, noise reduction, sensing capabilities and etc.Details
There are different types of capacitors available in the market. The key factor in distinguishing different types of capacitors is the Dielectric used in its construction. Some of the common capacitor types are ceramic, electrolytic (which include Aluminium capacitors, Tantalum capacitors and Niobium capacitors), plastic film, paper and mica.Details
