Hello readers, we hope you all are doing great. Welcome to the 1st lecture of Section 4 in the ESP32 Programming Series. In this section, we will interface the ESP32 module with common Embedded modules(i.e. LCD, Keypad, RTC etc.).
In today's tutorial, we will interface ESP32 with a 16x2 LCD and will display data using both Data Mode and I2C Mode. LCD is the most commonly used embedded module in IoT Projects. It is used to display different types of data i.e. sensor readings, warning messages, notifications etc.
Before going forward, let's first have a look at what is LCD and How it works:
16x2 LCD Module
LCD(Liquid Crystal Display) is a type of electronic display module that is used in a wide variety of applications and devices such as calculators, computers, mobile phones, ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to set up a free media server on Raspberry Pi. We also learned how to connect with different devices and stream media files. This tutorial will teach us how to use a Raspberry pi as a DNS server.
Prerequisites
You must have access to the following resources to follow this tutorial:
Raspbian Pi OS on Raspberry Pi (2-4).
Internet access is required.
There must be a unique identifier for every machine on the Internet to speak with each other Using IP addresses; clients can identify the servers they need to contact. However, no one is expected to remember the digits of an address; thus, DNS names are used instead. This DNS can be built on a Raspberry. It's a number-to-domai ...
Hello friends, I hope you all are doing well. Welcome to the 9th tutorial of our Raspberry Pi programming course. In the last chapter, we generated a PWM signal from our Raspberry Pi to control the brightness of an LED. We also studied different functions used in Python to perform PWM. In this chapter, we'll get a bit advanced with PWM and use it to control the speed and direction of a DC motor with the help of a motor driver IC.
To control the speed & direction of the DC Motor, we will:
Design a Circuit Diagram.Write Python code.
Components RequiredWe will use the following components to control the DC motor speed:
Raspberry Pi 4.DC Motor.Motor driver IC(L293D).Breadboard.
Jumper wires.
Controlling DC Motor speed wi ...
Hi Guys! Happy to see you around. Thank you for clicking this read. In this post today, I’ll walk you through Types of Cloud Computing.
Cloud computing is not a new term. Companies have been using this infrastructure for the past two decades. You might be familiar with this term, in case you don’t, cloud computing is the on-demand availability of computing resources over the internet. Simply put, you can process, store and manage a large amount of data using this architecture. The companies offering these services to end-users are called Cloud Service Providers (CSP). And most of these services offer the pay-as-you-go model which means you can ask for only those computing resources required for your business; you don’t pay for the resources you don’t use in the cloud computing model. This ...
Hello friends, I hope you all are doing great. Today, I am going to start a new tutorial series on Raspberry Pi 4. It's our first lecture today, so I will explain the basics of Raspberry Pi boards. In this tutorial series, I will teach you each and everything about Raspberry Pi and its programming. I have designed this guide for beginners, so we will start from the very basics and will slowly move toward complex concepts. Python programming language is used in Raspberry Pi boards, so we will study Python as well. So, we will learn both programming and hardware circuit designing in this tutorial series. Let's first have a look at What is Raspberry Pi?
What is Raspberry Pi?
Raspberry Pi is a series of Single Board Computer, developed by the Raspberry Pi Foundation in England, to teach co ...
Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to configure our raspberry pi for voice control. We also discussed some methods of reducing vexing noises so that the voice command program understands you. However, in this lesson, we will learn how to tweet from Raspberry pi.
What will we learn?
Assume you wish to add tweeting into a Raspberry Pi software you're developing. This article will show you how to build a Twitter app, get access privilege tokens, and post a tweet. On our Raspberry Pi, we'll make a simple program that tweets the result of the uptime command. This is a made-up example, but it demonstrates what is needed to tweet from a raspberry pi.
For this session, a repo has been set up. Because we'll be referring to code wit ...

Hello geeks, welcome to our new project. In this project, we are going to make a very interesting project. I think most of us have seen the scoreboards in sports, after looking at that, have you ever wondered about the working of it. Therefore, this time, we will be making something like that only with some extra features. So basically that score board is nothing but a counter which counts the scores. Most of the geeks who have an electronics background or have ever studied digital electronics must have heard about the counter.
Here, in this project, we are going to make an Up-Down counter. A simple counter counts in increasing or decreasing order but the Up-Down counter counts in increasing and decreasing order, both depending upon the input it h ...
In this article, we will discuss the introduction to organic chemistry in which we will study organic compounds, classification of organic compounds, types of formulas, use, significances, general and covalent bond characteristics of organic compounds, and homologous series and his characteristics. 9 out of 10 takes the organic chemistry too tough but I explained it easily and simply to you. This article is for beginners and clears many topics.
Introduction to organic chemistry
Old Definition:
“The chemistry of compounds obtained from living things.”
Vital force theory
Swedish Chemist Jacob Berzelius put forward this theory in the 19th century.
State
“ Organic compounds could not be synthesized in the laboratory due to the influence of a mysterious force called vital force, which occur ...
Hi guys! Hope you’re well today. In this post today, I’ll cover What is Industrial IoT (Internet of Things?)
IIoT is now a talk of mainstream conversation. This term has blown up in the past couple of years. Before we move further to describe IIoT, it is evident that industries are no longer dependent on the traditional production processes that happened to be costly and guaranteed no optimal results. Now companies are willing to incorporate automation in manufacturing and production processes. Smart systems, no doubt, are dangerous for the traditional labor workforce, but on the other hand, they create more opportunities for the people equipped with the latest business trends.
Curious to know more about Industrial IoT, how does it work, the difference between IoT and IIoT, examples of II ...
