The Internet of Things (IoT) and the Industry 4.0. Distinct technological revolutions but with a common goal: To integrate equipment (digital or analog) to a computer network.
And to be part of this revolution, the developer goes out of its way to include wired ethernet modules or WIFI modules in its circuits. Which increases complexity, circuit size and development cost.
What if I told you that already has a built-in WIFI microcontroller? And that it fits in the palm of your hand? For just 1 US dollar?
Today I’m going to introduce you to the ESP8266 microcontroller, from Espressif. And for those of you who already program in 8Bit microcontrollers like the Atmega328 (one of the most common on Arduino) and struggle to build your code in the modic SR ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide a detailed discussion on Introduction to Laser Sensor. Laser sensor is basically an electronic device which we often use for the detection of accurate positions as well as small objects. Laser sensors transmit or radiate laser light. This laser light consists of light waves having same wave length. Due to this fact laser light travels in a parallel direction from the source emitting this light. Due to its travel in parallel direction it can be transmitted over long distances. This light is dangerous for the human beings.
We must avoid by looking directly into the light. It causes serious eye damaging effect and even can make anyone blind. As we ...
Hi Everyone! I welcome you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to LM2576.LM2576 is a step-down voltage regulator, also known as a buck converter, mainly employed as a pre-regulator in linear regulators. The customized output version of this buck converter gives you the ability to set the output voltage as you like better. It is available with a remarkably good load and line regulation. Moreover, it is used to drive load under 1A and is available in fixed output voltages with 3.3V, 5V, 12V, and 15V.
I suggest you buckle up and read this post all the way through, as in this post I’ll detail the Introduction to LM2576 covering the datasheet, pinout, features, and applications. Let’s jump right in.

Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to TIP41. It is an NPN power transistor. It exists in (TO-220) malleable suite which marks this expedient appropriate for acoustic, power rectilinear and swapping submissions. Its corresponding transistor is TIP42. It is intended by joining three (3) components of semiconductor material by doping with different materials. It's center portion is base which is tinny and the other two outer parts are prominently doped than the base.
Several transistors can strengthen a trivial current which will then be leading adequate to effort attention or other greater current maneuvers. These discretion are proficient to notice a shift in voltage ...
Hello friends! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to 2N3772. I have already shared basic knowledge about different IC's and transistors in my previous tutorials e.g. Introduction to IRF540, BC547, MMBD914, LM339, LM224 and LM386. You must have alook at these tutorials before going into the details of this tutorials. It will be quite helpful in the better understanding of this article. 2N-3772 is basically a type of central semiconductor. It is basically a Negative Positive Negative (NPN) semiconductor. This semiconductor is designed by the process named as epitiaxial process. The main purpose behind its designing is to provide the high power based amplification proce ...
Hello readers, we hope you all are doing great. Welcome to the 4th lecture of Section 5(ESP32 Sensor) in the ESP32 Programming Series. So far, we have discussed the ESP32 built-in sensors in this section. Today, we are going to interface an external embedded sensor(i.e. PIR Sensor) with the ESP32 Microcontroller board. At the start, we will discuss the basics of a PIR Sensor(HC-SR501) i.e. its pinout and working. After that, we will design a simple project to detect the motion with a PIR sensor and ESP32. Finally, we will display the motion detection results on the ESP32 WebServer.
We will use ESP32 interrupts to detect the motion. Interrupts are used when a microcontroller needs to continuously monitor an event while executing other tasks at the same time. We have already posted a tuto ...
Hi Guys! Hope you’re well today. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to B772.
B772 is a medium power bipolar junction transistor mainly used for switching and amplification purpose and belongs to the PNP transistor family. It comes in the TO-126 package and carries a collector current of 3A which means it can support load under 3A. The 60V is the collector-base voltage and 30V is the collector-emitter voltage while 5V is the emitter-base voltage which means it requires 5V to bias the transistor and start transistor action.
In this post, I’ll be discussing pinout, datasheet, working principle, power ratings, physical dimensions, and applications of B772.
Let’s get started.

Hey Friends! We welcome you on board. I am back to give you daily dose of information. Electronic components play an important role in the designing and working of electronic projects. Today, I am going to unlock the details on the Introduction to 1n751a. It is a zener diode, also known as highly reliable voltage regulator, which is mainly used in industrial, commercial, entertainment and computer applications. It is slightly different than regular diode, as regular diode conducts in only one direction while zener diode can conduct in both directions. I will discuss every aspect related to this zener diode, so you don't need to go anywhere and find all information in one place. Let's dive in and explore, what is it about and what are its main appl ...
Hello Everyone! Happy to see you here. I welcome you on board. In this post today, I’ll be discussing the Introduction to BC558.

Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send an email using ESP32 module. We will also learn to send text files, images or some sensor readings using the SMTP server using the ESP32 module.
In IoT (Internet of things), there are various applications where we need to send emails carrying information like sending some sensor readings, altering emails, images, text files and much more.
What is SMTP?
SMTP or simple mail transfer protocol is an internet standard for sending and receiving electronic mail (or email) where an SMTP server receives emails from the email client.
SMTP is also used for setting communication between servers.
Various email providers like Gmail, Hotmail, Yahoo, etc. have unique SMTP ...
