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 UART is short for Universal Asynchronous Receiver / Transmitter....

Now we will see Quick Review of the Micromax A92 Canvas Lite and the features that are offered to the customers. Camera and Internal Storage Micromax A92 Canvas Lite packs a primary camera of 5.0 MP with Autofocus and LED flash. There is no secondary camera option present in this phone so this can be a disappointing one as the users cannot make the video calls due to the absence of the front camera....

In the process, we will also learn different types of shielding gases that are commonly used in MIG Welding. A Brief Note on MIG Welding Gas Metal Arc Welding or GMAW is the technical name to MIG Welding by the American Welding Society. Shortly after the development of the TIG Welding, engineers and scientists working on a new welding process. In this process, they used a continuous feed of metal wire as an electrode instead of Tungsten electrode in TIG Welding....

The information in the web pages can be Text in the form of HTML Documents, Images, Video, Applications etc. Web Browsers in your laptops and mobile phones are web clients. If you observed the terms Web Server and Web Client then yes, this type of communication is called as Client – Server Model....

Now it seems that Nokia is going for announcing the same on a special event which will be held in London again on 11TH July. The invites for the same has been already out by the name of ‘Reinvented’ and it confirms the date adding the time of 11:00 AM to it. This type of camera when came up with Symbian on Pureview 808 then created a lot of fuss among the users (even though this OS was not at all famous when compared with Android or Windows Phone)....

We will also see the differences between OLED and NanoCell TVs with respect to some important specifications (display type, viewing angles, burn-in, etc.). Finally, we will try to figure out which is the best for you in OLED vs NanoCell. So, let’s get started. What is OLED TV? OLED is short for Organic Light Emitting Diode. Even though it has the term LED (light emitting diode) in it, OLED is primarily used as display technology and rarely as a lighting source....

Plasma Interactive display solutions for classrooms are available in 4 sizes (50-inch, 65-inch, 85-inch and 103-inch) and come with integrated pen-touch capabilities via an Electronic Pen System. Up to 4 such pens can be used simultaneously for actions such as written annotation, drawing and moving items independently around the screen. These displays won’t be effected by the touch of your hands or clothes and will only detect electronic pens. Interactive plasma displays are equipped with cable free design and wireless capabilities....

Pull Pin Security Alarm Circuit Diagram: Components Required: LM380 Resistor 1k -3 Capacitor 0.1uF-4,250uf-1 Speaker-1 Description: The arrangement of the circuit is as follows. The circuit has a pin which is fixed to the pocket and the other end is attached to the circuit. The circuit remains inactive until the wallet is in your pocket as the circuit gets activated when the wallet is pulled from your pocket. When the wallet is in the pocket, the circuit has the pin attached thereby the circuit remains inactive....

Examples of operating systems are Windows. Linux, UNIX, apple leopard, Novel Netware, Solaris etc. All these operating systems come under general purpose operating systems (GPOS). If we look at real time operating system (RTOS) is also an operating system, which will also works as an interface between the hardware of the system and user. RTOS also do the functions like file management, process management, memory management etc. you people will have a doubt that if RTOS does the same functions like general purpose operating system (GPOS) then what is the difference?...

RS232 defines the signals connecting between DTE and DCE. Here, DTE stands for Data Terminal Equipment and an example for DTE is a computer. DCE stands for Data Communication Equipment or Data Circuit Terminating Equipment and an example for DCE is a modem. RS232 was introduced in 1960’s and was originally known as EIA Recommended Standard 232. RS232 is one of the oldest serial communication standards with ensured simple connectivity and compatibility across different manufacturers....

Galaxy Tab4 10.1 comes with a 10.1 inch WXGA 1280 x 800 display. The resolution remains same across the Tab4 7.0 and Tab4 8.0 with the only difference being the display size. Same 1.2 GHz quad core chipset runs throughout the Samsung Galaxy Tab 4 series, coupled with 1.5 GB RAM and 16 GB onboard storage. MicroSD support is 64 GB on all devices, but WiFi variant of Tab4 7....

We already made a dedicated guide on Parallel Circuits and also a comparison of Series vs Parallel Circuits. Check the above links for more information. What is Series Circuit? We already know from the previous tutorials that an electric circuit is combination of an energy source (voltage or current source), some components (resistors, capacitors, etc.) and metal conductors to connect them all. Electric Current flows from the energy source (such as a battery) to the load (such as a light bulb, which is essentially a resistor) through the conductors and the bulb glows....

CrossFire was developed by AMD, while Nvidia developed SLI. In this article, you’ll find detailed info to help you distinguish between them. So, if you’re ready, let’s start. What Is AMD CrossFire? CrossFire is a hardware technology crafted by AMD. Using Crossfire, you can use multiple compatible GPUs in a single computer unit. The motive here is to amplify the graphics performance and quality. What Is Nvidia SLI? SLI is the counterpart of CrossFire from Nvidia....

Solar concept is not new for us. As non-renewable energy sources are decreasing, usage of solar energy is increased. This solar energy is not only used on the Earth but also used in space stations where no electrical power is available. Here is the simple circuit to charge 12V, 1.3Ah rechargeable Lead-acid battery from the solar panel. This solar charger has current and voltage regulation and also has over voltage cut off facilities....

For the same, you can find a wide range of portable power options for charging your smartphone and other mobile devices. And out of all such options out there, you can primarily find solar chargers and power banks as the most viable options. To help you understand more about solar chargers and power banks as well as choose the right one between them, we are here with a complete comparison between solar chargers vs power banks....

Soldering Iron Vs. Soldering Gun: Definitions Soldering Iron You can think of soldering iron as a hand tool. As the name tells, it is used for soldering purposes. It is an electric equipment that heats the tip to melt the solder to join two work pieces. There’s typically a solder tip and a plastic handle involved in a soldering iron. Soldering Gun A soldering gun operates much like a pistol. Similar to the soldering iron, the soldering gun is also electrically powered....

Stepper Motor Control using 8051 Microcontroller Principle The main principle of these circuits is to rotate the stepper motor step wise at a particular step angle. The ULN2003 IC and the L293D Motor Driver are used to drive the stepper motor as the controller cannot provide current required by the motor. Circuit 1: Stepper Motor Control using 8051 Microcontroller & L293D The first circuit in this project is implemented using an L293D Motor Driver IC....

The counters which use clock signal to change their transition are called “Synchronous counters”. This means the synchronous counters depends on their clock input to change state values. In synchronous counters, all flip flops are connected to the same clock signal and all flip flops will trigger at the same time. Synchronous counters are also known as ‘ Simultaneous counters ’.There is no propagation delay and no ripple effect in synchronous counters....
