Welcome to the next tutorial of our raspberry pi programming tutorial. The previous tutorial showed us how to set up a weather station using the Internet of Things (IoT) on a Raspberry Pi 4. First, we studied how a weather station works on a fundamental level. Then we developed a Python script to collect data from the station. In contrast, we'll construct an automatic gate using a Raspberry Pi, a load cell, and an HX711 weight sensor.
These pressure-sensitive gates are common in shopping centers and showrooms; they open when someone is in the immediate vicinity and close again when the person is out of sight. Like the Automatic Gate, we just made, this one will open in response to weight or pressure and stay that way until the force is removed. If ...
Hello friends, hope you all are fine and having fun with your lives. Today, I am going to share a tutorial on DC Motor Speed Control using Arduino in Proteus ISIS. In my previous post, we have seen How to design a DC Motor Direction Control Project using Arduino in Proteus ISIS and if you haven't checked it out then I would recommend you to have a look at it first. Because, in today's tutorial, I am gonna extend that tutorial and will add the DC Motor Speed Control in it. So, today, we will control both the direction as well as speed of the DC Motor. Moreover, you should also have a look at How to use Arduino PWM Pins if you are not much familiar with PWM control.
In the previous tutorial, we have seen How to control the direction of a DC Motor, w ...
Hi Guys! I hope you’re doing great. Today, I am going to share Chapter Zero of the ESP32 Programming Course. I have called it Chapter 0 because today, we won't practically work on the ESP32. Instead, I’ll walk you through the detailed theoretical Introduction to the ESP32 Module, where we will discuss the ESP32 Pinout, Datasheet, Specifications, Features, Applications etc. in detail.
ESP32 is an embedded module that supports both WiFi and BT(dual-mode) connectivity and is thus used in Cloud-based IoT projects. ESP32 is the upgraded model of the ESP8266 module and is designed by Espressif Systems in China.
The following tables show the main features and technical specifications of the ESP32 module.
ESP32 Technical Specifications

Hello friends, hope you are fine and having fun with your lives. Till now we have seen two tutorials on Pixy Camera module, in the first tutorial we have seen How to Get started with Pixy Camera and after that we have seen How to Install Pixy Camera software which is named as PixyMon. So, now I hope that you have installed the Pixy camera software and have the Pixy Camera module in hand along with USB to Mini USB cable. Because in this tutorial we are gonna plug our Pixy Camera module with moduter and will upload the latest firmware in our Pixy Camera Module, which isn't much difficult and would be a piece of cake if you followed all the instructions carefully.
Pixy Camera comes with some old firmware which is up ...
Fluid mechanics is considered to be one of the essential branches of Mechanical Engineering. Fluid Mechanics comprises two words, fluid, and mechanics, with different meanings and research criteria. In this article, I will extensively introduce fluid mechanics and its importance in daily life. So without wasting any time, let us start:
Introduction to Fluid Mechanics
What is Fluid?
We remember in the early classes, we used to study three states of matter, and afterward, they became four named: Solid.Liquid.Gas. Plasma.
The definition of fluid is the state of matter that can be liquid or solid. We might have noticed that whenever the matter is in any stage, the criteria to know its state is to understand how much stress it can bear, and we name th ...
Companies usually outsource electrical engineering when internal capacity and project demand no longer align. A firm can be staffed well enough and still come under pressure once a few permit sets, coordination rounds, and late design revisions land at the same time. In that situation, outside support is less a strategic slogan and more a delivery decision.
Sometimes that help comes from a freelance electrical engineer brought in for a defined package. Sometimes it comes from a larger external team that can handle production work at scale. The appeal is fairly straightforward. A project keeps moving, the internal team has room to think, and the firm does not have to solve a short-term workload spike with a long-term hiring commitment.
Capacity ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you How to use Data types in Python. It's our 2nd tutorial in Python series. In our first tutorial, we have seen a detailed introduction to python and we have also installed PyCharm IDE to work on python.
Today, we will understand data types in detail as in order to design an efficient program, you need to select correct data types. Incorrect selection may cause memory loss and may slow your application. So, let's get started with data types in Python:
Data types in Python
Data Types are used for the classification or categorization of similar data packets. There are numerous data types available in python, which we can use depending on our projects' requirem ...
Today's post based on my personal experience so I thought of sharing it with you guys. Today I thought of using PICkit3 for programming PIC microcontroller. Before that, I was using PIC JDM Programmer for PIC , the only reason for switching is the usb port as I want to burn the PIC on my laptop instead of PC, as my laptop don't have serial port. So, I connected PICkit3 with my laptop and tested it with MPLAB and it worked well. But actually the project on which I am currently working demands MikroC (Client's requirement to use MikroC compiler but personally I always prefer MPLAB).
Anyways I thought it wont be much of an issue to connect it but when i practically did that i was kind of surprised, there was no method anywhere (at least i didn't fi ...
Hey Friends! This is a platform where we strive to keep you updated with useful information that exhibits technical aspect in any way so you don't get overwhelmed by all the data placed across the web and find all information in one place. Today, I am going to give you a quick review about e-commerce store that deals in electronic devices and components called WinSource which is an electronic components distributor from China. You must also have a look at BC107 - an NPN transistor which is an essential component for many electronic circuits mainly used for amplification and switching purpose.
If you are a student and technology geek, you need to streamline your electronic projects every now and then. You can find electronic components anywhere t ...
Hello Pupils! I welcome you to the board. I hope you are fine. In today's tutorial, we will design a project Metal Detector using 555 Timer in Proteus ISIS. All of us perceive the situations when at the public places such as on airports or in shopping malls where sharp metallic objects such as a knife or illegal guns or even a nail cutter are not allowed, there are walkthrough gates at every entrance so that any person with the forbidden material when passes through the gate, the alarming buzzer automatically switched on. This happened because the walkthrough gates have the Metal Detector circuit in them that works immediately when such a situation occurs.
In this session, we'll learn:
What are Metal Detectors?
How does the 555 Timer collabor ...
