Hello friends, today's post is, as the name suggests, about the Voice Recognition using EasyVR Shield. Voice recognition is quite a difficult task and usually done on software like MATLAB, but what if someone needs a stand alone project, a kind of autonomous voice recognition project, which doesn't use computer.
EasyVR is the solution for such projects. I recently did one project on this module named as Voice Recognition using EasyVR Shield and it worked really cool so I thought to share this new technology with you guys. I couldn't write the next part of Proteus tutorial, actually firstly I was busy in this project and then I thought to share this one as its quite exciting one. After completing this project, I will come back to Proteus tutorial.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I will provide you document on detailed discussion about Introduction to LM224. LM-224 has four internal builtin operational amplifiers. These amplifiers are frequency compensated. The basic purpose to design these type of device is to operate it from a single power supply sources. Moreover, they are also able to perform different tasks using split power supplies. Magnitude of power supply and the current current drain both are independent of each other.
LM-224 has a very wide range of application areas which include DC gain blocks, transducer amplifiers etc. LM 224 has a large number of amazing features include wide power supply ranges, large bandwidth, low input offs ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at a detailed Introduction to TCS3200. TCS3200 is a color-detecting sensor, it consists of TAOS TCS3200 RGB sensor chip and four white LEDs. It is used to detect visible color in a measurable range. This sensor has an array of a photodetector diode, some diodes are equipped with different color filters i.e. red, blue or green color and some diodes do not have any filter.
TCS3200 has different applications such as test strip reading, sorting by color and ambient light sensing. In today's post, we will have a look at its working, protocol, pinout, specification, etc. I will also share some links where I have interfaced it with other microcontrollers. If you have any questions about it ask in the c ...
Hi Friends! Happy to see you here. I welcome you on board. In this post, I’ll walk you through the Introduction to BC639. BC639 is a high current gain bipolar junction transistor that falls under the NPN transistor family. It constitutes a high collector current and low collector-emitter saturation voltage and is widely used for amplification and switching purposes. It is used to drive load under 500mA. Collector Dissipation is 0.625W while DC Current Gain (hfe) ranges from - 40 to 160 with transition frequency 200MHz. In this post, I’m going to discuss all nitty-gritty of the BC639 transistor covering pinout, working, power ratings, alternatives, applications, and physical dimensions.

Hello everyone, hope you all are fine and having fun with your lives. In today's post, I am going to share How to generate PWM in 8051 Microcontroller. PWM is an abbreviation of Pulse Width Modulation and is used in many engineering projects. It is used in those engineering projects where you want an analog output. For example, you want to control the speed of your DC motor then you need a PWM pulse. Using PWM signal you can move your motor at any speed from 0 to its max speed. Similarly suppose you wanna dim your LED light, again you are gonna use PWM pulse. So, in short, it has numerous uses. If you are working on Arduino then you should read How to use Arduino PWM Pins.
PWM, as the name suggests, is simply a pulse width modulation. We take a pu ...
Hello friends, i hope you all are fine enjoying. Today i am going to share a new project tutorial which is Getting Started with Arduino Programming. In the previous tutorial, which was titled as Getting started with Arduino Software, I have explained in detail the basics of Arduino software. How this software is installed and run.
Today's post is also related to arduino software but, the difference is that, in previous post we learn How to use the arduino software, What are the function keys of this software and Where to write the code(sketch) and after writing the sketch, how it is debugged. Now in today's post which is ' Getting started with Arduino Programming', we will see How a Code is written in Arduino software? What are the built-in functi ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to show you Arduino 74HC595 Interfacing and we will have a loook at How to Increase Arduino Output Pins with 74HC595. Suppose you are working on some project where you need to control 20 LEDs with Arduino UNO and you know we will 12 digital Pins so we can't control all of these 20 LEDs with Arduino UNO. We can use Arduino Mega as well but if we wanna stick to Arduino UNO then we need to increase its Output Pins and we will use 74HC595 for that purpose.
You should read this basic Introduction to 74HC595, it will help you to better understand this shift register. It's a Serial In Parallel Out Shift register and we will give it value serially from single Pin of Arduino and ...
Hello friends,I hope you all are fine and having fun with your lives. In today's tutorial, I am going to share a new Proteus Library named as Flex Sensor Library for Proteus. I am quite excited while sharing this one because we are the first one to design this library and share it online. Although, I wanna add one thing here that most of the flex sensors are analog sensors and their resistance changes over bending and believe me I have tried my best to design an analog sensor but despite the efforts we couldn't so I am sharing a digital version of Flex Sensor. So, its not gonna detect how much its bent but it will detect whether its up or bent. So, I thought to share it with you guys. It's better to have something than nothing. You should also have ...
Hello everyone, I hope you all are fine and having fun with your lives. Today, I am going to share a very basic project named as Line Following Robot using Arduino. I have designed a three wheeler robot and have placed IR sensors beneath it to detect the black line and then I have made it move over this Black Line.
This Line Following Robot is not doing any extra feature i.e. turning or rotating back. It will just simply move in the straight line. I have also posted a short video at the botton of this tutorials which will give you better idea of how this robot moves. You should first read this tutorial and design the basic robot and once you are successful in designing the basic Line Following Robot then you should have a look at my recent Project ...
In today's tutorial, we are going to see how to install Arduino driver in Windows. In the previous post, we have seen what is Arduino? and why is it so popular and whats its use? Now, afer getting the basic knowledge of Arduino, the next step you need to do is to install Arduino driver in your computer so that it got recognized by your computer as Arduino. If you don't install the Arduino driver in Wndows then you won't be able to program Arduino using Arduino software.
tis tutorial is quite basic and is for the newcomers, who wants to start working on the Arduino software, if you have already run some codes on your Arduino then its not for you. You can skip it. Anyways, It's quite easy and it won't take much time. So let's get started with it.
I ...
