Hello readers, I hope you all are having fun in your lives. Welcome to the 2nd Chapter of Section-2 in the ESP32 Programming Series. In today's lesson, we'll go over another built-in feature of the esp32 module that helps it stand out from the competition: BLE or Bluetooth Low Energy. In the previous tutorial, we discussed the Classic Bluetooth in ESP32, which is considered the predecessor of Bluetooth Low Energy(which we are going to discuss today). We will first look at, what is BLE? and why is it used?, and then will design some examples to utilize the ESP32 BLE in Arduino IDE.
What is BLE?
There have been numerous adjustments and upgrades to Bluetooth's characteristics since its inception, where Bluetooth 4.0(also called BLE or Bluetooth Smart) is the most influential.
B ...
Major League Hacking, also known by its official acronym MLH, organizes student hackathons. MLH was established in 2013 by Mike Swift, who previously worked for SendGrid and Jonathan Gottfried, who formerly worked for Twilio. The two are former developer evangelists.
All hackers at MLH events have, for the last two years, been getting a special voucher code from Domain.com. With this coupon, and several other deals, the students at each event can register a free domain (.com, .net or even .org), get better prices on hosting.
Additionally, the most innovative domain name at each MLH event gets rewarded with a bag full of great hacker gear.
What exactly is MLH?
At first, MLH was intended to facilitate North American student-run university hackathon ...
Hi readers! Hopefully, you are doing well and exploring new things daily. We live in an era where technology is growing faster every day. Imagine a world where you can play casino games with Bitcoin, bypassing traditional banking hurdles and enjoying unparalleled convenience and privacy. Today the topic of our discourse is the Online Casino Industry.
One area where the online casino business shines is embracing innovation to improve user experience and processes. The emergence of crypto coins such as Bitcoin, Ethereum, and others has paved the way for innovations in payment methods, with far-reaching opportunities within the space. Through blockchain technology, cryptocurrency is revolutionizing transactions into faster, more secure, anonymity-based alternatives to traditional banks.

Hello friends, I hope you are doing great. Today, I am going to share an expert level project which is ECG Averaging in MATLAB. If you are new to ECG then you should have a look at Introduction to ECG. I have already shared ECG Simulation using MATLAB in which we have seen how to simulate an ECG signal and then diagnose heart disease. We have also extracted ECG features in that project. So, if you guys haven't read that tutorial then I would suggest you to not read this one. First read ECG Simulation using MATLAB and then you should read this tutorial. Today's project is quite an extension of our previous project ECG Simulation using MATLAB. Our team has designed this project after quite a lot of effort that's why its not free to ...

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I would like to provide a complete discussion on Introduction to C945. You will see a detailed description on the basics of the transistor C-945 and its different parameters. I have already shared Introduction to MMBD914, 74HC245, NE556, LM348 and PIC18F4550. So, must go through these tutorials in order to have better understanding about different IC's. C-945 transistor is basically a Negative Positive Negative (NPN) bipolar junction transistor.
C945 is usually used in the electronic circuits where there is a need of high speed transistor and a low current. C-945 has three semiconductor regions named as emitter, base and collector respectively. Since C-945 is a bipolar ...
Hello Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to BD136.
BD136 is a medium power general-purpose transistor mainly used for switching and audio amplification purposes. It belongs to the PNP transistor family and comes with collector current 1.5A, indicating it can drive loads under 1.5A. The amplification factor ranges from 40 to 250, which means it can amplify the input signal up to 250 times. Both collector-emitter and collector-base voltages are 45V while the emitter-base voltage is 5V, indicating only 5V is required to bias this transistor.
I suggest you read this entire post, as I’ll be detailing complete introduction to BD140 covering pinout, working principle, power r ...
Hello friends, I hope you all are doing great. In today's tutorial, we will have a look at How to Create a Custom Filter in ASP.NET MVC. It's our 10th tutorial in ASP.NET MVC series. In our previous tutorial, we have cleared our concepts about Filters in ASP.NETMVC and we have also implemented one built-in filter of ASP.NET MVC.
Now, its time to have a look at How to Create a Custom Filter in ASP.NET MVC, in which you can specify your own authentications or handling etc. In our ASP.NET applications, we have use custom built filters a lot for different purposes. So, let's have a look at How to Create a Custom Filter in ASP.NET MVC:
Create a Custom Filter in ASP.NET MVC
In ASP.NET MVC, custom filters are handled by a base class named as ActionFil ...
In this tutorial, we will walk through the process of interfacing a pH sensor with an Arduino UNO in Proteus. To make the project more practical and user-friendly, an LCD is included so that both the sensor’s voltage output and the calculated pH value can be displayed clearly in real time. This allows the user to easily monitor the readings without needing additional software or serial monitoring tools.
The term pH, short for “potential of Hydrogen,” indicates the concentration of hydrogen ions (H⁺) in a solution and is used to determine whether it is acidic, neutral, or alkaline. A pH of 7 represents neutrality, values below 7 indicate acidity, and values above 7 represent alkalinity. Monitoring pH is essential in several fields—such as water quality testing, agriculture, food processing ...
