Worldwide, there are a lot of Samsung Galaxy smartphone users and integrating ESP32/Arduino Bixby can help them easily automate their devices and homes within the Samsung ecosystem. The method we are describing to integrate does not require a hub. So, for the Samsung smartphones such as S22 Ultra, using the Bixby voice control, we can turn on/off our devices or add more automation. For this … [Read more...]

ESP32 Arduino IoT Relay Control with Google Home, Alexa and Manual Switch
Recently I have discovered a no-code IoT platform named SirnicPro for Arduino, ESP32-based projects which offers almost everything the professional IoT devices allow. No-code platform means the Arduino sketch is automatically generated. Practically there is nothing to learn since everything is click, configure and generate. This is kind of project is quite difficult to produce with a … [Read more...]
Getting Started with Arduino IoT Cloud with ESP32
Arduino IoT platform is great particularly if you want to avoid backend configuration, and management and want a nice mobile app UI. There are certain differences with self-hosted IoT solution and platforms such as IBM Watson IoT. As it is officially from the creators of Arduino, it is easy on certain parts of the work but it is obscured too. The documentation is not easy for everyone and that is … [Read more...]
ESP32 Arduino IoT Relay Control (PHP MySQL Based Self Hosted)
This is the first guide for the series of guides to replace the setup for IBM Watson IoT based projects. If you look at our old articles and GitHub repository, you will realize that we were publishing IBM Watson IoT-centric sketches for the past 4 years. A significant time and effort were spent and our innocent readers were using them. Suddenly they came to know that IBM Watson IoT platform will … [Read more...]
How to Create Own PHP Based IoT Webserver for ESP32 Arduino
You can create your PHP MySQL-based personal IoT web server, even use WordPress or some PHP-based admin panel, toggle button, gauges etc. We can always send HTTP POST Request to a Secure Webpage with PHP, but that will need a web server which will support the protocol. You can do it with ThingsBoard, but that is not what we are talking about. We are talking about a simple setup where you … [Read more...]
Reading Voltage With Arduino
Reading voltage with Arduino is easy. You'll need only a potentiometer to adjust the resistance. Despite being easy, this project is great for kids because it explains the basics of the 5V logic of electronics. The components you need are a breadboard, an Arduino Uno R3, a potentiometer and two jumpers. With digital input, 5V is perceived as HIGH and 0V as LOW. But, electricity does not only … [Read more...]
How Ultra-Wideband Technology Works
Ultra-Wideband Technology (UWB technology) has been a highly-anticipated, promising technology for the commercial market. The most important feature is its use of extremely large frequency ranges with a bandwidth of at least 500 MHz. Ultra wide bandwidth (UWB) signals are based on pulses of the shortest possible duration. UWB signals don't contain complete sinusoidal oscillations. When they are … [Read more...]
5 Ways to Keep Your Computer Safe
We rely on our computers more and more every day. They are an essential part of our lives, both professionally and personally. Computers store so much of our data, and sadly cyber attackers are constantly looking for any weakness they can exploit. So it's essential to keep them safe from harm to avoid a wrong moment. These five steps will keep your computer and privacy safe from online criminals … [Read more...]
ESP32 Arduino WS2811 Pixel/NeoPixel Programming
The WS2811, WS2812, WS2812B, WS2813, and SK6812x are known as NeoPixel or Pixel. They are RGB LEDs with a controller. Particularly WS2811 RGB LED strings are commonly sold in India during Diwali and in North America during Halloween, Christmas etc. Bhoot Chaturdashi in India and Halloween in North America are equivalent. Indian wedding typically involves a lot of lighting. These occasions … [Read more...]
ESP32 Arduino : Control LED with a GUI Toggle Button
Designing two buttons with separate ON/OFF functions is easy and usually, we can avoid async server or dynamic programming language. When we need a checkbox, we can use Javascript on the server side. iOS style toggle button is essentially a checkbox (or a radio button or it can be anything similar). Fundamentally toggle button is a "cheating"! You can create a toggle switch just with CSS 3. It is … [Read more...]
What to Look For When Buying a 4K Laser Projector
A home theatre experience should be easy to set up and use. Since there are many projectors to buy, you need to think of the price and features. If you don't care about cost, but do want plenty of features then one option is perfect for you. Another great choice if the price isn't a problem is to go with one of the other great options. The cost of 85-inch and 98-inch television is huge and … [Read more...]
