Hello readers, hope you all are doing great. In this tutorial, we will discuss low power modes in ESP32, their purpose and their implementation to increase the battery life by reducing power consumption.
Purpose of Low Power Modes
Fig.1
Along with multiple wireless and processing features, ESP32 also provides us with a power-saving feature by offering sleep modes. When you are powering the ESP32 module from the live supply using an adaptor or a USB cable, there is nothing to worry about power consumption. But when you are using a battery, as a power source to ESP32, you need to manage the power consumption for longer battery life.
Low Power Modes in ESP32
When ESP32 is in sleep mode, a small amount of power is required to maintain the state of ...

This post is the next part of our previous post Financial Calculations in MATLAB named as Implementation of Black Litterman Approach in MATLAB, so if you haven't read that then you can't understand what's going on here so, its better that you should first have a look at that post. Moreover, as this code is designed after a lot of our team effort so its not free but we have placed a very small cost of $20. So you can buy it easily by clicking on the above button.In the previous post, we have covered five steps in which we first get the financial stock data, then converted it to common currency and after that we calculated the expected returns and covariance matrix and then plot the frontiers with and without risk free rate of 3%. ...
Hi Friends! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through Latest Proteus Libraries for Engineering Students V2.0.
We have been designing proteus libraries for our blog readers for quite a while now. You might have visited our Arduino Libraries for Proteus V2.0 and Analog Sensors Libraries for Proteus V2.0. We keep working on those libraries and make sure the bugs are removed and you always get the updated version of those libraries.
We are going to share the most advanced and upgraded version of Proteus Libraries V2.0 we have designed for our readers. These libraries are more robust, fast, and efficient than previous versions. Moreover, we have converted some digital sensors to analog sensors, helping ...
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 friends, hope you all are having fun in your life.
Today's tutorial is about the component designing in Proteus ISIS. This tutorial actually deals with the presentation of your project. Usually when students give presentation of their projects, then it is asked that add the circuit diagram of their project. Now when students open Proteus in order to design their circuit, they found out that the components they have used in their project are not available in the Proteus Directory. Now what to do ?
In that case, there's a need to design your own component in Proteus and place it in the circuit. Although, this new designed component won't work as the real co ...
Hi Fellas! I am back to give you a daily dose of valuable information. Today, I'll give you a detailed Introduction to IRF3205. It is an N-Channel HEXFET Power MOSFET that comes in a TO-220AB package and operates on 55V and 110A. It is mainly used for dynamic dv/dt rating and consumer full bridge applications.
Additionally, it falls under the category of ultra LOW on-resistance devices based on Advanced Process Technology, making it a building block of the electronic applications where fast switching is a major concern.
In this post, I'll cover each and everything related to this transistor, its main features, working, pinout, and applications. Let's get down to the nitty-gritty of this tiny component.
Introduction to IRF3205
IRF3205 is an N- ...
Hello friends, hope you all are fine and enjoying. Yesterday I got a mail from a friend, and he requested me to explain a tutorial about Seven Segment Display. So today, I am going to share my new project tutorial which is Seven Segment Display using 555 Timer in Proteus ISIS. It is a very simple project to understand Modern Digital Electronics.
As you all know, now a days all the Digital Display’s uses Seven Segment Display. So first of all let’s have a little introduction about Seven Segment Display. How they are fabricated and how their LED’s glow in such a beautiful manner? Seven Segment Display (SSD) is the form of electronic device, used to display decimal numbers. Seven Segment Displays are commonly designed in Hexagonal shape but according ...
Hello readers, we hope you all are doing great. In this tutorial, we are going to demonstrate how to interface and control a servo motor using an ESP32 board. After that, we will demonstrate how to create a webserver to control the servo motor’s shaft position with the ESP32 board.
Servo Motors are among the most important actuators in robotics, with applications ranging from RC planes to automated door locks.
Hardware components required
A servo motor
ESP32 development board
Connecting wires
Breadboard
Servo Motor
There are several specific types of electric motor applications in which the motor must rotate only at a specific angle. For such applications, we need a special type of motor with such a special arrangement that causes the m ...
Hi Friends! Hope you are doing great. Today, I am going to give you a detailed Introduction to Arduino Uno. It is a microcontroller board developed by Arduino.cc and is based on Atmega328 Microcontroller. The first Arduino project was started in Interaction Design Institute Ivrea in 2003 by David Cuartielles and Massimo Banzi with the intention of providing a cheap and flexible way for students and professionals to learn embedded programming.
Arduino UNO is a very valuable addition in electronics that consists of a USB interface, 14 digital I/O pins(of which 6 Pins are used for PWM), 6 analog pins and an Atmega328 microcontroller. It also supports 3 communication protocols named Serial, I2C and SPI protocol. You should also have a look at this vid ...
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to access Firebase (a real-time database) to store and read values or data with ESP32.
It is Google’s mobile application development platform that can be used to can access, monitor and control ESP32 from anywhere in the world with its (firebase) real-time database.
What is Firebase?
Firebase real-time database is a development platform provided by Google which included multiple services to manage and authenticate data.
Firebase is basically a mobile and web app development platform I as works great with Android APIs) that includes features like firebase cloud, real-time data and Firebase authentication etc.
As per Firebase’s official documentation (https://firebase.google.com/docs/database), whenever a us ...
