What is Arduino Shield? Arduino Shields are add-on boards than can be plugged on top of an Arduino board and provided additional capabilities and functionalities to an Arduino Board. They have the same pin position as an Arduino Board and are usually designed to implement a specific function. Why Do We need Arduino Shields? While it is easy to play around with Arduino by placing components on a breadboard, it is not a preferrable option to design a final product with breadboards....

IMPORTANT NOTE: I have mentioned this already in the previous tutorials but I will repeat it in every LPC1768 Tutorial. Download both the Datasheet and User Manual for LPC1768 MCU from the official NXP website. I cannot explain / discuss each and every topic in detail. You have to look up for the topic of discussion in those documents and gather additional information. Introduction DAC is short for Digital to Analog Converter....

A Brief Note on LuminAID Before diving in, I want to talk about LuminAID and why we chose this particular brand. While we were looking for Solar rechargeable lights, we came across some offerings from LuminAID. After reading about them and watching their humanitarian work, we became fully invested. The catastrophic earthquake that struck Haiti in 2010 was the triggering point in starting LuminAID. Anna Stork and Andrea Sreshta started LuminAID as an answer to the question: What could we do to help in such situations?...

Introduction Today’s personal computers are more powerful than ever. The technological development in the PC hardware space has been tremendous particularly in the fields of processors and graphics cards. Irrespective of how powerful a computer is, you have only a couple of ways to interact/communicate with it: using keyboard and mouse. A keyboard has number of switches using which you can type letters or send commands. You cannot use a keyboard as a pointing device (technically, you can but it is not ideal)....

Don’t worry. We are here to help you. In this guide, we will see all the basics of surround sound and the Multi-Channel Home Theatre Audio System. Introduction The term “Home Theatre” has different meanings for different people. Enthusiasts and movie lovers might dedicate an entire room to home theatre. They fill up the room with a screen and projector (usually this is the case but sometimes a large screen TV as well), a cool sound system, comfortable chairs, lighting, etc....

What Is A Multimeter? A multimeter is an electronic device to measure all the different parameters of electricity. An electrician uses a multimeter to check different aspects of electric circuits and appliances. The different aspects include measurement of current in amp, voltage in volt, and resistance in ohm meter. There are two types of multimeters available in the market; analog and digital multimeter. Digital multimeters are more popular as they are more accurate in readings....

Hence, RC oscillators are more suitable for low frequency applications. An RC oscillator consists of an amplifier and feedback network. This feedback network is a phase shift network made with number of capacitors and resistors which are arranged in a ladder fashion. That’s how this oscillator is also called as ladder type RC phase shift network. The basic principle of the RC phase shift oscillator is that before feeding back a portion of the output of the amplifier to the input, the amplifier output passes through a phase shift network....

The intake of energy is also low. One of many features of RV microwaves includes their vibration confrontation, which makes them bear any bump on the roads. It also heats the food more quickly and saves time. A fan is present inside the microwave, which spreads the hot air eventually on the food. Advantages and Disadvantages of RV Microwaves PROS: It makes it safe to cook food in it. Comes in a dense project....

Jammer circuit produces the high-frequency signal which will confuse the receiver of the particular system from receiving the signal, even though circuit is working properly, user of the system feels that circuit is not working properly. This type of high frequency signal generation through jammer is called noise and the circuit is called jammer because it will mix the main signal with noise signal. Now let us know about simple FM Radio Jammer Circuit and its working....

The size of the display is 4.5 Inches which is available with the resolution of 480 x 854 pixels (which is not that clear but matched the PPI index of Micromax Canvas 2). The processor available with this device is the Dual Core Processor which is clocked at the frequency of 1 GHz and supported by the RAM of 512 MB. The primary camera available on this device is 5MP and that of the secondary camera is 1....

But one component that most people neglect is the primary storage drive. Other than the storage capacity offered by it, you should also check the type of storage drive that you get. This is due to the reason that you can find both HDD and SSD drives out of which an HDD offers more storage and an SSD offers much higher storage speeds. But if you wish to know more in detail, here is a complete comparison between SSD vs HDD for Gaming....

It is powered by a 1.5 GHz CPU with 1 GB of RAM and an internal storage of 4 GB, which will have an option to be expanded up to 32 GB via microSD card....

Car Batteries on the other hand are designed to supply the necessary short bursts of high energy to start the car. Hence, they are also known as Starter Batteries. Once the car is started, the car’s alternator will kick-in and produces the required power. An important difference between Deep Cycle Batteries and regular Car Batteries is that deep cycle batteries can be discharge up to 80% of its capacity (although it is not recommended to discharge a battery below 50%), whereas the car battery must be almost fully charged at all times i....
