IoT IR Remote Control with ESP32 Arduino and IBM Watson IoT

In this article, we are discussing the overall hardware, code and library we will need. This article is not about building one particular project. Infrared (IR) remote control technology is widely used in day to day used devices. IR remote control signals are a reliable resource to control nearby electrical appliances. With the development of ESP32 like cheaper system on chip and Internet of … [Read more...]

How to Run an ESP32 on Battery

The operating voltage range of ESP32 is 2.2V to 3.6V. The ESP32 boards have an LDO voltage regulator to keep the voltage at 3.3V. The output of the regulator is also broken out to one of the sides of the board and labelled as 3V3 which can be used to supply power to the other components. The VIN pin can be used to directly supply the ESP32 a regulated 5V voltage electricity supply. In other words, … [Read more...]

Strategic Benefits of “as-a-service” with Hybrid Cloud

To maximize the benefits of hybrid cloud infrastructures, we can consider the as-a-service services of specialized providers for the management of these mostly highly complex IT infrastructures. By leveraging cloud infrastructures, organizations save costs, become more agile, and drive innovation faster. This is also shown by various surveys. Many of the IT decision-makers see it as a prerequisite … [Read more...]

Call for Code 2020: Coding Challenge to Save Mankind from Pandemics

Call for Code is a coding competition. We talked about Call for Code in the year 2018 and 2019 too. It is a multi-year initiative with 5 years commitment from IBM. To the developers, Call for Code is a chance to use the latest technologies to create a long-lasting cost-effective solution. In this year’s Call for Code Challenge, one of the themes is to mitigate the impact of global pandemics like … [Read more...]

ESP32 vs Arduino : How ESP32 is Different from Arduino

ESP32 is a low cost, low power consuming System on Chip (SoC) with integrated Wi-Fi and Bluetooth compatible with Arduino IDE. In other words, an ESP32 board can be used as "Arduino" following some guide like we have published one in the past. ESP32 is developed by Espressif Systems and has a Tensilica Xtensa LX6 microprocessor. By the phrase "Arduino", we mean the boards which are designed and … [Read more...]

How the Post-Quarantine Era Will Be for the IT Workers

The quarantine measures for coronavirus pandemic was an apt measure to control it. However, its impact already has been obvious to the whole world from an economic perspective. Quarantines travel bans, and home-stay resulted in a decline in consumer spending. Many businesses are operating at a loss. While many startups are struggling to close. These factors are resulting in unemployment and … [Read more...]

How to Scale Automating Operations for your Business

Automation solutions are gaining attraction in a wide variety of industries. Many companies rely on automation tools (such as process automation) to relieve employees of time-consuming tasks. The disadvantages force to scale such solutions. The appropriate tools have the potential to solve challenges in process automation, reduce costs and increase efficiency in the departments from finance and … [Read more...]

Linking data from different systems is at the top of the to-do list in application handling. There are many solutions for this, each with advantages and disadvantages. Apache Kafka promises to solve the problem in the way that users have … [Read more...]

ESP32 Arduino Smartwatch Detector with Buzzer

The series of article Samsung Smartwatch as Proximity Switch taught our readers to learn all required the basic to make ESP32 to respond to a specific smartwatch's BLE. The same basic was used for the IoT project Detect Smartwatch With ESP32 on IBM Watson IoT Widget. But, still today in everyday life we depend on sound clues more than the visual clues. A door bell or a smoke detector are some … [Read more...]

What is Scalability in Cloud Computing?

Scalability describes the ability of a system to grow in magnitude. Although the word scalability does not exist in the dictionary of the SAR the closest scalable adjective is of little use in telecommunications and computer engineering. Scalability, is the desirable property of a system, network or process, indicating the ability to react and adapt without losing quality, or manage the continuous … [Read more...]

What is a Cloudlet in Cloud Computing?

A cloudlet is a small-scale data centre located at the edge of the Internet to provide computing resources to mobile applications with lower latency. It is a newer architectural element of cloud computing infrastructure of a 3-tier hierarchy: mobile device or IoT hardware, cloudlet, cloud. The cloudlet concept is also known as mobile micro-cloud. The term was first suggested by Satyanarayanan as … [Read more...]
