Hello readers, I hope you all are doing well. Welcome to the Section 2 (ESP32 Features) of the ESP32 Programming Series. ESP32 is equipped with numerous built-in features and in each chapter of this Section 2, we will explore one of these ESP32 features in detail.
In the previous Section(Section 1: ESP32 IDEs), we installed different software IDEs to program ESP32 boards. Among these IDEs, we are going to use Arduino IDE for programming ESP32. So, I hope all of your tools are configured properly and you are ready to explore the built-in features of ESP32.Today's the 1st Chapter of Section 2, and here we will discuss How to communicate with ESP32 Bluetooth Classic from a smartphone using Arduino IDE.
Here's the video tutorial for ESP32 Bluetooth Classic:

Hi Friends! Hope you are doing well. I always feel pleasure to keep you updated with information related to engineering and technology. Today, I'll unlock the detailed Introduction to LED. The LED stands for Light-emitting diode. LED is a PN-junction diode mainly used as the source of light.
The LED has a leg over common orthodox incandescent light in terms of efficiency, low consumption power, compact size, longer range and an ability to retain the quality for a longer period of time. It comes with a wide variety of applications ranging from automotive headlamps, camera flashes, aviation lighting, traffic signal, and medical devices.
In this post, I'll try to cover each and everything related to LED, so you don't need to wrestle your mind browsin ...
Hey pals! I wish you are doing great. Welcome to a new lesson about the Digital Logic Circuits in The Engineering Projects. In the past tutorials, we Designed the Basic JK Flip Flop. Today, we'll talk about the following Points:
What are JK Flip Flops?
What are the Master Slave Flip Flops?
How does the Circuit of Master Slave Flip Flop looks?
How types of JK Flip Flop different from each other?
How does the simulation of Master JK Flip Flip take place in Proteus ISIS?
Moreover, we'll also learn some key concepts in DID YOU KNOW portions. Yet Let's recall some points about the topic. Flip Flops are the building block of a huge number of electronic systems and devices. A Flip Flop is a Digital circuit that can take the bits as input, wor ...
Hello friends! I hope you are having a good day. Today, I am sharing a new version of Arduino Library for Proteus(V3.0). I have already shared the previous versions of this library i.e. Arduino Library for Proteus(V1.0) and Arduino Library for Proteus(V2.0). This newer version is way better than previous versions because of its realistic design and better performance. I will discuss the comparison in detail in just a bit. This Proteus Library zip file has the following types of Arduino microcontrollers in it:Arduino UNOArduino Mega 1280Arduino Mega 2560Arduino MiniArduino Pro MiniArduino Nano
We will move towards the installation, but before this, let me share the basic introduction of Arduino.
What is Arduino?
Arduino is an open-source family of microcontroller boards that is designe ...
Hello everyone! I hope you all will be fine and having fun. Today, I am going to give you a detailed Introduction to MAX232. It is an Integrated Circuit(IC) embedded in a single chip and acts as a voltage-level converter. MAX 232 is capable of converting 5V TTL Logic level to TIA/EIA-232-F level and can take up to +-30V input. It is normally used for the communication between microcontroller and Laptop/PC.We can use MAX-232 to convert Transistor Transistor Logic (TTL) voltage level to RS232 and vice versa. RS232 is the method of transferring data using serial communication. MAX 232 is a dual receiver or driver having a capacitive voltage generator to supply RS232 voltage levels from a single supply of 5V. Each receiver converts RS232 inputs to 5V either Transistor Transistor Logic (TTL) ...
Hey Guys! I aspire you a very happy and promising life. My job is to give you daily dose of information so you can stand out of the party. Today, I am going to uncover the details on the Introduction to 2sc4793. It is an NPN (Negative-positive-negative) bipolar junction transistor (BJT) which is mainly used for amplification and switching purpose. I'll give you a brief details about this transistor and try to cover as many aspects as possible related to this transistor. Let's hop on the board and explore what kind of transistor is this and what are its main applications? Let's get started.

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.

Hello friends, I hope you are all fine and will be doing something interesting in your life. in today's post, I am going to discuss Introduction to DHT22. It is a temperature and humidity measure sensing device. It is easily used but it needs a specific time for an operation. Its temperature measuring range is from -40 to +125 degrees Celsius with +-0.5 accuracy. This sensor measures moisture content and temperature. This sensor is easily connected to other microcontrollers.
DHT22 plays an important role in our environment in measuring temperature and moisture. It is a low cost easy-to-use small sensor. This sensor is used at different weather stations to measure temperature and ratio of moisture in the air, in this way, they tell about tem ...
Hi Friends! Glad to see you here. I welcome you on board. In this post today, I’ll be discussing the Introduction to BC327. BC327 is a bipolar junction transistor that falls under the family of PNP transistors. It is composed of silicone material and is used to drive load under 800mA. It’s a current-controlled device that carries three pins where small current generated at the one terminal is used to control large current at the other terminals. Read this post all the way through as you’ll get to know all nuts and bolts of BC327 covering pinout, working, power ratings, applications, and physical dimensions.
