In our previous guide on ESP32 Arduino With LCD, we used an I²C module. OLED displays with I²C are sold as one unit. These days, they does not cost huge. In our earlier guides we have explained about different protocols, interfaces like I²C, Serial Peripheral Interface. Another relevant tutorial is breadboard power supply module). We are using a 0.96 inch SSD1306 OLED display (blue/white) … [Read more...]

Here also you will get unique articles and news on computer hardware, Software, Networking and Protocols.
What Is a Serverless Microservice?
In our few previous publications, we discussed the commonly asked matters around serverless, FaaS, microservices such as Serverless Functions vs Microservices, Difference Between FaaS and Serverless etc. What Iis a Serverless Microservice? Serverless microservice is combination of both serverless and microservice. Serverless microservices run within vendor's serverless infrastructure only when … [Read more...]
Basics on Role of VPN in the Field of IoT for Maintaining Session Privacy
Ever experienced a breach of your privacy or security while online? A compromise of your credit card details, for instance? Did you ever wonder how it became possible that your boss knew you streamed the first three episodes of the latest season of the Game of Thrones on the torrent account, using the office's broadband connection? Ever thought how IoT prototyping can breach your security? Welcome … [Read more...]
Serverless Functions vs Microservices
Both the Serverless and Microservices reduce the time to market. Microservices is a technical term where as serverless has more a marketing term like the Cloud has when compared to virtualiation. Essentially, both Serverless and Microservices allow handling changing requirements with lesser effort which results lowering of the operation costs in the environments with larger load. Microservices are … [Read more...]
ESP32 Arduino With LCD : Connection & Code (I2C, LCD 1602A)
1602A LCD and I²C module are quite cheaper and easy to setup and code. Earlier, we have published guides on how to wire and setup 1602A LCD with Arduino UNO (which have not used the I²C module) which occupies 8 Pins on your Arduino. We have also explained about different protocols, interfaces like I²C, Serial Peripheral Interface and discussed interfacing 1602A LCD display using I²C Serial … [Read more...]
What is the Difference Between FaaS and Serverless?
One of our reader asked us why we have used Serverless and FaaS as interchangeable words in the article What Are the Real Use Cases of Serverless Architecture (FaaS)?. He is correct. Serverless and FaaS are not exactly the same. The main reason we used the terminiogies synonymously is that, the intended reader audience likely are begginers and need the basic concept, we think that confusing them … [Read more...]
Difference Between Data Science and Big Data
When we say Big Data, we are talking about the humungous volumes of non-totaled crude information with its size fluctuating up to petabytes. Big data refers to the huge volumes of data of various types, i.e., structured, semi-structured, and unstructured. If you want to learn big data science in depth and get certified too, then Intellipaat big data training is your need. Intellipaat is one … [Read more...]
What Are the Real Use Cases of Serverless Architecture (FaaS)?
In our an earlier article, we discussed about the limitations and disadvantages of the Serverless Architecture (FaaS). Now, what are the real use cases of Serverless Architecture (FaaS) which a developer should think to use it? A Serverless Architecture helps us by offloading the computational efforts on Cloud Web Services. The functionality, scalability, and security goes to the backend provider. … [Read more...]
ESP32 Arduino Wi-Fi Access Point with Wi-Fi Connection (Station)
It is possible to setup ESP32's Wi-Fi to access point and station. ESP32 can connect to another hotspot and share the connection. An access point (AP) is a networking hardware device which allows other Wi-Fi devices to connect to a network. Some basic theory required to know for making basic code better. An AP is different from a hotspot. Hotspot is the physical location (and the device) … [Read more...]
Machine Learning With Quantum Computers
Unlike a desktop computer based on transistors working on binary data, the quantum computers work on qubits whose quantum state can have an infinite number of values. Small quantum computers were built from the 1990s. Until 2008, the major difficulty concerns the physical realization of the basic element: the qubit. The phenomenon of decoherence (loss of quantum effects on the macroscopic scale) … [Read more...]
What Are the Drawbacks of Serverless Computing?
Serverless computing or FaaS provides a platform which allows the developers to execute code upon call of events. The serverless platform separates infrastructure services from the applications running on top of the platform. Automatic scaling functionality of FaaS not reduces the compute cost but and operational management overheads. In the serverless solution, we pay for the managed servers, … [Read more...]
