Arduino boards power supply

Hello People. This article is about Arduino boards power supply. There are several power pins on an arduino board.

The different power pins are as follows:

  • VIN. This pin can take input voltage to the Arduino board when it’s using an external power source (as opposed to 5 volts from the USB connection or other regulated power source). You can supply voltage through this pin, or, if supplying voltage via the power jack, access it through this pin.
  • 5V. This pin outputs a regulated 5V from the regulator on the board. The board can be supplied with power either from the DC power jack (7 – 12V), the USB connector (5V), or the VIN pin of the board (7-12V). Supplying voltage via the 5V or 3.3V pins bypasses the regulator, and can damage your board. We don’t advise it.
  • 3V3. A 3.3 volt supply generated by the on-board regulator. Maximum current draw is 50 mA.
  • GND. Ground pins.

The Arduino Uno can be powered via the USB connection or with an external power supply. The power source is selected automatically.

External (non-USB) power can come either from an AC-to-DC adapter (wall-wart) or battery. The adapter can be connected by plugging a 2.1mm center-positive plug into the board’s power jack. Leads from a battery can be inserted in the Gnd and Vin pin headers of the POWER connector.

The board can operate on an external supply of 6 to 20 volts. If supplied with less than 7V, however, the 5V pin may supply less than five volts and the board may be unstable. If using more than 12V, the voltage regulator may overheat and damage the board. The recommended range is 7 to 12 volts.

Arduino boards power supply


There are mainly three methods of supplying power to arduino board. The Vin, 5V, 3.3V, and GND pins are Arduino power pins. You can use the Vin pin to Power your Arduino with an unregulated 7 to 12-volt power source. Like a 9V battery or a wall adapter that is in the range of 7 to 12 volts. Alternatively, you can power your Arduino through the 5V pin with an external regulated 5V power supply. It can be a wall adapter that gives out constant 5V or a DC-DC converter that is connected to a battery or a set of batteries. You can use both the 5V pin and the 3.3V pin to provide power to modules that are connected to the Arduino. But you can’t use the 3.3V pin to power your Arduino Uno/Nano.

Clients for Mobile app development

Hello People. This article discusses how to get clients for Mobile app development. Finding clients is a major problem for IT startups and entrepreneurs. Here are few useful tips to get clients for app development companies.

Firstly highlight the skill you are expert in. For example we have good command over android development so what we would do is that we find websites which have no apps yet in the playstore. We will drop a mail to owner on that website that you are lacking much audience because this era is of app users and there are trillions of folks using smart phone. We can build your app at a very reasonable price. In this scenario if client gets ready you could be able to build up portfolio.

You can also try getting business through LinkedIN. Visit your profile page on LinkedIN from your mobile app or desktop, and if business feature is turned on for you, you’ll see a box under your profile photo/headline that talks about how to showcase the services you provide. Click “Add Services,” and then fill out the form to provide details about the services you provide. Be as detailed as possible so members who view this section have a good sense for what you provide. Click “continue” and this will automatically be added to your profile.

Clients for Mobile app development

For finding clients on linkedIn, you must have a good connection with your targeted audience. You can search clients by their posted requirement like: “Looking for the freelancer designer or developer”. Once you type a statement like this one in the search box you will get the list of a result as you have to sort the list by “Content”. Then you can able to view all the posts related to that “keyword/requirement”. You have to pitch to that Author who has posted the requirement. You can simply comment or you can connect with him for further discussion.

Node Red and its application

Hello People. This article explains you What is Node Red and its application. Node-RED is a programming tool for wiring together hardware devices, APIs and online services. At the core of Node-RED is Node.js, which (as you know) is a JavaScript runtime that has an active community.

Because of its ease of use, node-red is ideally suited for building IOT and Home control dashboards and automations as well as many other applications.

Node-Red IOT and Home Automation

Industrial IOT and home automation applications will generally use one or more of the following protocols.

  • MQTT
  • HTTP

Nodes for these protocols are part of the core nodes.

Node Red and its application

Various platforms

Node-RED can be used on various platforms. That’s because Node-RED itself is a Node.js application. If you have a runtime environment for Node.js, you can run it. It is mostly used on Edge devices, cloud services, and in embedded formats.

The perfect starting point for Node-RED applications is the ADAM-6700 series modules that come complete with Node-RED installed, plus onboard I/O and an extensive built in library to assist with utilising the ADAMs functions. Other functions and sample code can be added from other Node-RED users or by building your own applications and importing them into other projects you may do in the future.

An example of an application using Node-RED could be for a specific signalling arrangement for alarm monitoring. This could include analogue, serial, or ethernet devices all covered in a single unit that provides email and SMS support via a network. It could also include a dashboard on the local network with raw data that the alarms are based on, with logging on board using an SD Card.

A router using Node-RED can provide monitoring of 4G signal reception, alerts for signal loss, network performance and data usage just to name a few. As with modern equipment, Node-RED can provide benefits to make products intuitive to the user’s requirements whether for additional features or just using the dashboard function for service acknowledgement or fault reporting.

Software Development company for IoT projects

Hello People. This article discusses how to choose a software development company for IOT projects. The Internet of Things is a concept in which many everyday appliances and consumer electronics are computerized and connected to the Internet. Choosing an IoT developer today is very difficult.

IoT development cost

IoT development is very complex and therefore cannot be cheap. Immediately eliminate companies that offer their services 2-3 times cheaper. You will probably end up with a low-quality product if you choose them.

Blog posts and social media

Regular posts on social networks and a blog by a company indicate that the company has something to share with the audience. It is a great way to understand IoT’s level of expertise and company scale. It is enough to read a few articles to understand the material’s relevance and cultural level.

Plan for long-term

When it comes to the corporate, planning for the long term is the best. As it is a far-reaching, well thought, and comprehensive strategy that has the capability to change your life completely, the former applies to it too. 

Additionally, there’s always a level of uncertainty associated with this dynamic and disruptive technology, that may lead to unpredictable consequences in the future. This calls for the need for long-term planning that allows you to stay prepared for or unexpected events and take actions based on the ever-changing business environment and changing technologies.

Software development company for IOT projects

Figure out the basics

While your business might be successful with the adoption of this smart technology, relying on mere data collection may lead to failure in the next phase of a project. IoT is more than just collecting data with the help of connected devices, and you must consider several other factors to make your IoT project successful. 

It’s worth brainstorming how you are supposed to gain profitable business values from your internet-connected assets. Moreover, while you are collecting data, you need to make sure that it is driven by the real-world needs of a business and is organized properly. 

Secure IoT Private Networking

Protecting and securing your data is a serious business regardless of what industry you’re in. To have secure networking it’s better to create different ways for customers to build and own their IoT private network from end to end.

Regardless of whether you’re utilizing AWS VPC peering, AWS Direct Connect or IoT LANs, the IOT development company should plan to scale their customer’s business without compromising on their data.

Cost of developing an IOT app

Hello People. This article discusses about Cost of developing an IOT app. From 2020, Internet of Things software development is in huge demand.

Major factors that influence your IOT development budget:

  • Number and complexity of IoT app features 
  • IoT UX complexity
  • UI requirements (number of screens, style guide)
  • App security level
  • Device types on which it should work
  • Operating system and API integrations

In addition to the above factors, IoT requires building hardware from scratch or existing hardware optimization. For this you need to conduct research regarding existing hardware options and then test and choose that one that may be suitable for your IoT business idea execution. In the case of creating hardware from scratch, the process includes lots of costly stages such as Analysis, Modeling, Prototyping, and Testing. 

Cost of developing an IOT app

You will also need IoT network and middleware. Middleware is about third-party device integration and digital ecosystem maintenance.  The type of application and its complexity also may vary. A Simple IoT app has limited device connection options and only basic features. The budget may start from $30,000

A Sophisticated IoT app could have a large number of advanced features. It includes APIs, GPS tracking, payments, and other smart device integrations. This may include sync, third-party API, and security tool integration. The product development should be estimated at $50,000 as a minimum.

The hourly rates of programmers also matter. Development outsourcing remains the most cost-effective solution, as it allows you to choose specialists from the global talent pool. At the same time, there are also outsourcing risks with respect to the failure of your project execution completely or partly as a separate factor. IOT developers charge 100 to 150 dollars per hour.

Compared to other sorts of digital development, building an IoT app is a new area where lots of challenges haven’t yet got specific solutions. IoT development involves creating a unique digital infrastructure. It is hard to predict the final cost, as there are numerous factors that may influence it. Hardware issues, difficulties with API integration, maintenance plan, unique solution promotion are among them.

IoT application in the Environmental Sector

Hello People. This article discusses about IoT application in the Environmental Sector. Using IoT, we can monitor and control our environment closely. We can also use this technology to predict environmental disasters. In that way we can implement damage-control early-on.

We can use real-time data sets to spot substantial contamination early on. Using IoT-enabled technology, such as drones, GPS sensors, animals can be detected and tracked in real-time. A potential outbreak on infectious diseases can be prevented much more efficiently. Livestock can be equipped with RFID chips, and RFID scanners. 

We can develop an IoT-system that monitors wastewater and provides a system-wide reporting solution for potential sewer overflow or discharge. It depends on water level sensors located inside manholes. These IoT-sensors relay information to a server that alerts users via an App or SMS about the potential spill-over and overflow.

IoT application in the Environmental Sector

Businesses can implement IoT systems and AI technology, to monitor their hardware. If a part has turned faulty, the IOT system may redirect the consumer to the nearest authorized repair shops.

Using IoT technology, different servers and data centers can be connected. Data centers connected through IoT technology will be able to monitor their servers in real-time . As a result money and energy can be saved, whenever the server load is lower than usual.

Many drivers in congested cities waste a considerable amount of time and money trying to find a parking space. Cities can employ IOT systems that automatically alert nearby drivers of empty parking spaces.

IoT technology can play a crucial role in smart agriculture. By attaching different sensors to crops and trees, one can gain insightful data on hydration level, nutrient levels, diseases etc. This may also decrease the use of chemical fertilizers and pesticides.

MVVM pattern in KnockoutJS

Hello People. This article discusses about MVVM pattern in KnockoutJS. Model-View-ViewModel (MVVM) is an architectural design pattern for developing software applications. This pattern is derived from Model-View-Controller (MVC) pattern. The advantage of MVVM is that it separates the application layer’s graphical user interface from business logic.

Knockout: KnockoutJS is a pure JavaScript framework to implement the MVVM design pattern in the web application development. The main key concepts of KO are:

  • Declarative Bindings
  • Automatic UI Refresh
  • Dependency Tracking
  • Templating

MVVM is responsible for handling data from the underlying model in such a way that it is represented and managed very easily. ViewModel in MVVM represents an abstract version of View’s state and actions. The view classes do not know that Model and ViewModel classes exists, also Model and ViewModel does not know that View exists. Model is also unaware that ViewModel and View exists.

MVVM pattern in KnockoutJS

Let us see the definitions of Model-View-ViewModel (MVVM) .


View is a Graphical User Interface created using markup language to represent data. View binds to properties of a ViewModel through data-bind concept, which indirectly connects to the model data. View need not be changed for any alteration done in ViewModel. Changes made to data in ViewModel is automatically propagated in View due to binding.


Model is domain data or business object, which holds real-time data. Model does not carry behaviors. Behavior is mostly implemented in business logic.


ViewModel is the center place, where data from Model and View’s display logic are bundled together. ViewModel holds the dynamic state of data. There is an implicit binder in between View and ViewModel to communicate with each other. This binding is inclusive of declarative data and command binding. Synchronization of View and ViewModel is achieved through this binding. Any change made in View is reflected in ViewModel, and similarly any change in ViewModel gets automatically reflected in View. Existence of this 2-way binding mechanism is a key aspect of this MVVM pattern.
