In this tutorial, we’ll learn how to use device-to-device (D2D) communication to make daily life a little simpler. For example, you’ll be able to control household appliances, such as the coffee machine, a light switch, or the AC — and do so from inside your vehicle. So, if you’re arriving home one evening, the presence…

Video is basically data; rather we can term it more aptly as a signal. The signal can be transmitted as analog or digital signal/data; but the thing which remains in the background is that what makes this signal so special. Let us look at this that “how video is displayed on a screen”. First we…

By Krupa Bhavsar, Applications Engineer, Dialog Semiconductor Sine waves are continuous waves, which describe a smooth periodic oscillation. These waves are generally used in signal processing and engineering fields In this article, dual sine waves with opposite polarity as shown in Figure 1 are generated without coarse PWM “steps”. For generating sine waves, one PWM…

Everyone who owns or wants to own a PC needs to know about motherboard. We all are always interested in Processor, memory-RAM, storage- Hard Disk. But we all tend to forget the most important component which ties all the above – Motherboard.Motherboard is glue which binds all the components of a Computer. Every component directly or indirectly attached/installed/connected to a system has a connection to motherboard, because it is the base on which system & its components/peripheral devices stand and perform. Technically speaking motherboard is a PCB- Printed Circuit Board that provides an interconnection to almost every component present in a PC. It is also known as system/main board. There are various roles that a motherboard plays. The important ones are: It acts as glue which binds all the components together. It’s main job is to coordinate with the various operations performed by the various components; it serves as a interface for all the modular singular components of a system like Central processing Unit – CPU, Random Access Memory – RAM, Storage device – Hard Disk ( Magnetic or Solid State); to provide slots and expansion cards to enhance the functionality of a system. There is development of new devices with new interfaces every day. Motherboard need to provide the slots to include the functionality; to deliver the power to the various components and devices as per their requirements.

如今，每当有关于下载电影，电视节目系列或任何大型文件等大型文件等的话题时，洪流是最常用的单词。有关文件文件的地址和信息。因此，什么是洪流，洪流如何成名，它们如何提高下载速度而不影响带宽以及与传统下载有何不同？现在是时候看看该软件如何获取数据了。Torrent文件可用于对等方法的方法共享下载方法，即根据其可用性以不同的作品下载文件。洪流正在使用不同的术语，您会遇到种子，水力学，节点，同伴，群等。

被用作一种无触摸方法，可为对象提供精确的距离测量，或者简单的“在那里/不存在”逻辑，接近传感器涵盖了广泛的技术，每个技术都提供了自己的一组操作原理，优势和缺点。便携式或小型嵌入式系统中一些最常见的技术包括超声波，光电，激光…

该项目与我们在DC电机控制上介绍的项目有所不同。到目前为止，这些文章包括有关控制直流电动机速度的洞察力：Arduino A an Arduino A a avr / pic / pic / arm microcontroller这次这次是AVR / PIC / ARM微控制器A远程SMS蓝牙，我们将通过…覆盖DC Motor Speed Speed Control

作为最终设计的经常被忽视或不足的方面，DC电源连接器（也称为枪管连接器）为为许多应用提供了供电的关键连接点。尽管在设计过程中是一个相对简单的组件，但对DC Power Connector的规格和命名法具有基本了解仍然很重要。规格…

In today’s age of connectivity, smartphones and tablets are becoming more of a necessity rather than a luxury. Whether it is not to miss important mails, being updated with the news or finding directions when lost – connecting to the Internet anytime and anywhere is becoming an integral part of our lives. It’s now possible to get internet access in any location as long as your phone gets a good signal from the cellular network.You can also use public Wi-Fi hotspots to connect to the Internet through a shared connection. So how exactly does the Internet, which was made for computers, work on your mobile phone?First, let’s see what Mobile Internet is. In simple terms, Mobile Internet is a smaller Internet scaled down to fit the dimensions of a web browser on a mobile phone. The mobile phone network is an example of a cellular network.

As we see the above procedure for developing as wired mouse for a purpose. The positive and the negative terminals are the output terminals. Then we see at the other end of the mouse orange and white are to be joined as we have no use of those, then we see to connect green and blue wire for negative and positive of the battery. Then here is the concept “when we apply the infrared radiation from the TV remote to the bottom of mouse (i.e. at bottom of the chip) the output terminals go high about 1.5-2 volts for 1.5 seconds then clearly we find it as a trigger (oneshot)” then we can use this for the various purposes. For the counter, i.e. the remote IR LED is fixed in the axis of IC chip then o/p is connected in the place of the clock for serial reload counter.

鼠标是计算机最重要的外围之一，尤其是对于那些不是基于触摸屏的人。令人着迷的是，如何根据需求，形状，指向技术等如何使用各种类型的计算机鼠标。曾经只有球鼠很普遍。适当的表面是…

Electricity is a must for electronic devices to power up and run smoothly. However, even minor fluctuations from a power source can be hazardous to the devices and appliances that rely on it. Although many of us take electricity for granted, to conserve power in certain cities, supplies are cut short for set intervals —…

Zigbee has often been regarded as a mini version of Wi-Fi. Keeping some features like range, power consumption apart, zigbee and wi-fi are often used in similar applications in terms of household based wireless communication. These short range wireless technologies even share common ISM band of 2.4GHz, use same spread spectrum technique. Interestingly, both of…

Second Generation (2G) technology was launched in the year 1991 in Finland. It is based on the technology known as global system for mobile communication or in short we can say GSM. This technology enabled various networks to provide services like text messages, picture messages and MMS. In this technology all text messages are digitally…

Since the invention of the Internet, a new era of convergence of technologies has ushered, bringing close distant technologies which could not have been thought to be related at all. Sure, we can send a mail from our GPRS activated cellular device, but is the reverse true? Can we send a text message from the Internet? The answer is yes and we all have used free online SMS sending websites either on a regular basis or just for testing if it works or is merely faking. The best and the most attractive part is the word ‘free’ and sometimes, ‘unlimited’ too. But have you ever wondered how this is made possible? We’re going to cruise along the path an online SMS would follow in the whole process in the next few pages.

编译器和解释器都执行相同的目的 - 将高级语言（例如C，Java）转换为二进制形式，这是可以通过计算机硬件理解的。它们包括用于执行高级程序和代码以执行各种任务的软件。特定的编译器/口译员是为不同的高级语言设计的。然而，…

GSM (Global System for Mobile Communication) and CDMA (Code Division Multiple Access) are two dominant technologies for mobile communication. These two technologies differ in the way calls and data travel over the mobile phone networks take place. On comparing both the technologies GSM has some limitation when the call quality is concerned but still has…

Even after rebooting your computer you get exact date and time. Have you ever given it a thought that how is it possible? The answer is pretty simple; there must be an independent power source running a clock which runs even when system main power is off. Let us explore it. RTC- Real…
