NXP Semiconductors LPCXpresso ]]>Development Platform]]> includes low-cost LPCXpresso target boards to boost development. LPCXpresso Development Boards work with the NXP ARM Cortex MCUs, the LPCXpresso IDE (Integrated Development Environment) and other industry leading partner toolchains.


The ]]>LPCXpresso boards]]> feature an LPC target MCU, a connector for external debug probes, and Arduino Uno and Pmod™ shield connections for access to more off-the-shelf expansion hardware (MAX, V2, and V3). LPCXpresso boards are easily upgraded with hardware expansion baseboards, Arduino shields and Pmod boards (MAX, V2, and V3).

The target portion of LPCXpresso boards can be connected to expansion boards to provide a variety of interfaces and I/O devices. The on-board debug probe can be used to debug other targets (all board types except MAX versions).

Designing an Open loop Boost Converter SMPS Part 1.1

Designing an Open loop Boost Converter SMPSIn this tutorial, an open loop boost converter SMPS will be designed. The Boost Converter is one of the topologies of Switched Mode Power Supply (SMPS). It has a DC source as Input power like a battery, generator or rectifier. In the case of a boost converter, the output power is always greater than the input power.

So, the boost converter circuit will step up the power from one DC level to a higher DC level. The method of converting one DC voltage to a different DC voltage is called DC to DC conversion. The boost converter is a DC to DC converter which steps up the input signal to the higher voltage level.

Scientists Create Sensor that can Transform any cloth into Fitness TrackerA group of researchers from the Harward University in the US has developed a soft, stretchy fabric-based Sensor that can turn any cloth into a fitness tracker. It’s a highly sensitive soft capacitive sensor composed of silicone and fabric that moves and flexes with the human body to unobtrusively and accurately detect movement.
 
The technology involves a thin sheet of silicone i.e. a poorly conductive material which is flanked by two layers of silver-plated, conductive fabric i.e. a highly conductive material, forming a capacitive sensor. This kind of sensor registers movement by measuring the change in capacitance, or the ability to hold electric charge of the electrical field between the two electrodes.

Everyone must be familiar with the term - Switched Mode Power Supply or SMPS. Yes, they are used in every personal computer. In fact, the Switched Mode Power Supply is widely used with many other devices. Once it is understood that what SMPS actually is, its countless applications can be easily imagined. 
 
An SMPS is used for converting the electronic power supply efficiently. Any SMPS has some storage components which store electrical energy to supply to the load device and some switching components which turn on and off at high frequencies charging and discharging the storage components.

Li-Fi: Using Visible Light for Lightning Fast Data Transmission

Li-Fi: Using Visible Light for Lightning Fast Data TransmissionThe ubiquitous nature of the internet is probably a major reason for making our lives the way it is today. In the present scenario, it has become a necessity of the modern world. Its capabilities are not limited to over knowledge regarding the usage of Wi-Fi. Another superior technology of Li-Fi is ultimately going to change our perception of the internet.

Wi-Fi is a commonly used wireless technology which uses radio waves to connect devices to the internet but with the growing demands and increase in the network congestion, the present technology won’t be able to deliver the desired results for a long time. Consequently, while exploring the possibility of alternate choices the term ‘Li-Fi’ was devised. Here we are going to illustrate the concept of Li-Fi technology, how does it work, and how is it different from the conventional Wi-Fi technology.

Make a Battery Level Indicator using LM339 IC (Part 7/9)

Make a Battery Level Indicator using LM339 IC This era is an era of portable devices. Like smartphones and tablets are small computers that can be taken anywhere, more and more gadgets that can be taken anywhere are the new craze. These light-weight and portable devices are being developed in domains of electronic applications. All such devices are run on batteries.

The batteries are the lifeline of all such devices. The use of batteries itself though requires certain precautions. The most common issue with the use of batteries is their overcharging and over discharging. Also, it is important to keep track of the charge level of batteries attached to a device, so that it can be timely charged before it discharges to the level that the device gets nonoperational.

Arduino LCD: How to Connect a Liquid crystal display up to the Arduino

Arduino LCDYou are aware of various pros of an LCD (liquid crystal display) and its ability to perform and therefore in this Arduino LCD tutorial of arduinomylifeup, we will learn how to connect a simple 16×2 LCD up to the Arduino with this good little device.

If you had some experience with the LCD boards, you must be aware of the fact that they are not assembled with header pins and hence, will need to be soldered on. With the availability of header pins, you can perhaps skip soldering but getting a worthy connection to the board will be challenging. The potentiometer in the circuit is used to control the brightness of the screen.

Designing Closed Loop Non – Isolated Boost Converter SMPS Part 1.2

Designing Closed Loop Non – Isolated Boost Converter SMPSThe open loop boost converter designed in the previous tutorial did not have constant and regulated voltage at the output. For a stable output, a Boost converter with error detection circuit needs to be designed. The error detection can be done by adding a feedback circuit which continuously checks the error in the output voltage and provides a regulated voltage at the output.
 
Therefore in this tutorial, a closed loop non–isolated boost converter is designed. The boost converter can be designed in two ways- Open loop boost converter and Closed loop boost converter. In the former, there is no feedback from output to input contrary to the closed loop which has a feedback circuit. So, the output of an open loop boost converter is not regulated. In the latter, there is a feedback from the output to the input. So, the output of a closed loop boost converter is regulated. 

Designing Open Loop Non-Isolated Boost Converter With Adjustable Output Voltage (Part 1.3)

The open loop boost converter designed in the previous tutorial had a fixed output voltage respective to the input voltage level. The output voltage of the circuit can be made variable by drawing the output through a variable resistor. The output voltage in this circuit still remains unregulated as no feedback is used.

Therefore in this tutorial, an open loop non–isolated boost converter is designed. The boost converter can be designed in two ways- Open loop boost converter and closed loop boost converter. There are certain design parameters involved in the designing of the boost converter. It is important to understand these design parameters. Any boost canverter can operate in either of the two possible modes of operation.
