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 everyone! I hope you all will be absolutely fine and having fun. Today, I am going to provide you the discussion on Introduction to LM393. LM-393 has two internal operational amplifiers. These are internally frequency compensated. These are specifically designed to perform their tasks using a single power supply sources. LM-393 can also perform its operations properly by using split power supply. The current drain supply does not depend upon the magnitude of the power supply.
One of the most amazing feature of LM 393 is that ground is included in its common mode input voltage. Moreover, LM 393 has a lot of features e.g. wide voltage supply ranges, a very small current drain supply, low input offset current, low input bias current, output v ...

Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation. If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons.
First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.).
Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly).
Because of these two reasons, we have to use the driver in between t ...
