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 ...
Hello everyone and welcome to this article. Previously we have been discussing different types of PCB boards and for sure we have not exhausted everything. Today we are going to focus on a very important aspect of the PCB design which is the thermal characteristics of the PCB's working environment. Up to this moment, we have interacted with boards that work best in normal working conditions. But remember there are some working conditions, that have very harsh environment such as high temperatures. Let us take for example temperature in boilers or even electric heaters. Do you think normal FR-4 boards can survive in such temperatures? Don’t you think they will melt off if exposed to high thermal radiation? Your guess is as good as mine. For us to h ...
Hello Everyone! Happy to see you here. I welcome you on board. In this tutorial, I’ll walk you through the Water Sensor Library for Proteus. You won't find this library in the proteus software, and we are introducing it for the very first time. It will help you to better understand the working/ operation of the water sensor.
If you want a proteus library of any sensor, that is not available in proteus already, you can share it in the comments below, I’ll try my best to create and share that library asap.
Before I go further, it’s better to scratch and get a hold of what is a water sensor? A water sensor is an electronic sensor, used to detect the presence of water. It detects the water by measuring the water's electrical conductivity. These sen ...
Hello friends, hope you all are fine and having fun with your lives. Today's post is about getting started with pixy camera. Now, the first thing comes in mind is what is Pixy Camera so let's first have a little introduction about Pixy Camera on which I recently worked. Pixy Camera is a small camera board which uses NXP microcontroller. Its a very powerful board and can get easily interfaced with simple Arduino UNO board. So, now we can do image processing even on Arduino UNO. Image Processing needs a powerful board that's why we can't interface simple webcam with Arduino UNO or mega etc. Before using pixy camera, when I need to do on board image processing I always used either Arduino YUN, Raspberry Pi or Arduino USB host shield but still it was ...
Hello readers, I hope you all are doing great. In our previous tutorials on raspberry pi Pico, we discussed the basic features, architecture, download and installation of development environments for raspberry Pi Pico programming. In this tutorial, we will learn how to access and control Raspberry Pi Pico and its GPIO pins to implement LED blinking using MicroPython.
Introduction
Raspberry Pi development boards are quite popular and frequently used among students and hobbyists. But the drawback of Raspberry Pi is their cost i.e., around $35-$45. So when cost of the development board is of prime importance the users prefer to use ESP8266, ESP32, Arduino, PIC etc. over Raspberry Pi. To overcome this drawback, Raspberry Pi foundations designed a new board i.e., Raspberry Pi Pico which is a ...
Hello Friends! I am back again to fill your appetite with more knowledge and skills. Today, I am going to explain the details on the Introduction to BF259. It is a bipolar NPN (negative-positive-negative) silicon transistors which comes in metal casing. It consists of one P layer that lies between the two layers of N doped semiconductor. I am going to cover all aspects related to this bipolar transistor. Let's get started and have a look, how it works and what are the applications it finds useful.
Introduction to BF259
BF259 is a bipolar silicon transistor which is made up of two N doped layer and one P doped layer.
It is mainly a three terminal device which consists of emitter base and collector.
P terminal of the transistor acts like a ba ...
Hello everyone, I hope you all are doing great and having fun. In today's tutorial, I am going to share a new software which I have named Serial Terminal. I have designed this Serial terminal in vb2010. You can download this software from below button. I have already posted a complete tutorial on How to use Serial Port in Visual Studio 2010 in which I have explained how to send and receive data via serial port. It was quite a basic software, which just transmit and receive data from a serial port but today I am gonna provide you a complete serial terminal, which will not only transmit and receive data but will also display that data in different formats.
As shown in the below figure, first of all you need to select the COM Port from which you want ...
Hello everyone, I hope you're all doing well. In the previous lecture(Chapter 0: ESP32 Pinout), we discussed the ESP32 features & specs in detail. Today, we are officially starting this ESP32 Programming Series. In this ESP32 Programming Series, we will start with basic concepts and
will gradually move towards complex topics. I will try to keep this
ESP32 series as simple as I can. But still, if you encounter any issues,
please ask in the comments, will try to resolve the issues as soon as
possible.As ESP32 has numerous features & applications, so I have divided this series into different sections. I have named the 1st section "ESP32 IDEs". In this section, we will discuss different IDEs used to program ESP32 boards. In each Chapter of this section, we will install one of t ...
Hello friends, I hope you all are having fun. Today, I am going to share the 9th tutorial of Section-III in our Raspberry Pi 4 Programming Course. In the previous tutorial, we interfaced an air pressure sensor BMP180 with Raspberry Pi 4. In this tutorial, you'll learn how to interface an MQ-2 gas sensor with a Raspberry Pi 4. Many apartments, residences, and workplaces rely heavily on these gas sensors to detect smoke or gas and alert the appropriate personnel in an emergency. In addition to gas and smoke, this sensor is sensitive to various odorous gases.
Project DescriptionToday, we will interface a gas sensor MQ-2 with Raspberry Pi 4 and will display the values on Raspberry Pi Console Window.
Components Required
These are the components use ...
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 ...
