Hello Guys! Hope you’re well today. Happy to see you around. I welcome you on board. In this post today, I’ll detail the Introduction to 1n5822.
The 1n5822 is a Schottky diode that comes with a low forward drop voltage around 0.525V which means it needs 0.525 voltage to conduct the current in forward biased direction. It supports a load under 3A and is an ideal pick for switching applications with low current ratings. And the 40V is the maximum repetitive peak reverse voltage Vrrm of this tiny device.
Just bear with me for just 2-min as I’ll be discussing the datasheet, Pinout, specifications, and applications of this tiny little device.
Let’s get started.

Hello readers, today we will learn about the messaging protocol supported by ESP32(called MQTT protocol), which is used for IoT applications. The communication protocol to be used for data transmission and connectivity in web-enabled devices depends upon the type of IoT application.
The Internet of Things (IoT) is a network of interconnected computing devices like digital machines, automobiles with inbuilt sensors, having unique identifiers and the ability to communicate data over a network without the need for human intervention.
Before implementation, let's first have a look at what is MQTT Protocol?
What is MQTT?
MQTT stands for Message Queuing Telemetry Protocol and is a messaging or communication protocol used for IoT applications.

Hello learners, Welcome to another tutorial on signals and systems. We are learning about the responses of the signals. We all have experience in situations where the change in the frequency of a system, such as radios or control systems, results in a change in the working or result of that system. So we have the idea that frequencies play an important role in different types of systems. In the previous lecture, we saw the impulse response of the system. Our mission today is to learn about the frequency response of the LTI system. We will learn all the basic information about the topic and will revise some important points as well. To do this, have a look at today’s concepts:
What is the LTI system?
What is frequency response?
How is frequency response performed without the function i ...

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 LM258. LM-258 has two internal Operational Amplifiers (Op-amps) which are frequency compensated internally. They are specially designed to perform their tasks from a single power supply source using a wide range of voltages. They can also perform different operations using split power supply. LM-258 low power supply current drain does not depend upon the magnitude of the power supply source.
LM 258 has a lot of features including high DC voltage gain, large bandwidth, different input voltage equal to power supply, large output voltage swing, common mode input voltages include ground. These were the few of m ...
