In the previous post we have seen the project description of Voice Recognition Project using EasyVR shield. Today we will have a look at Getting started with EasyVR commander. EasyVR shield is a module which is used for voice recognition. First of all, we save our commands in the EasyVR shield and then we use these commands to control anything. In this project, I need to control the robot with voice commands like when someone says FORWARD then the robot start moving in forward direction.
Now first of all what I need to do is to save this FORWARD voice in the shield, which we will see today how to save the command in the shield and after that I will show you the Interfacing of EasyVR shield with Arduino UNO. So that when I say Forward the motor sta ...
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 ...
Hi Guys! Happy to see you around. I welcome you on board. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to JRC4558.The JRC4558 is a single silicon-chip monolithic dual operational amplifier. This amplifier is a high-performance device and is internally compensated. It is widely used in sample and hold amplifiers and pedal circuit designs. The JRC4558 is available with a remarkable input impedance of around 5 MO, a high voltage gain of around 100 dB, and a good slew rate of around 1.7V/µs.
I suggest you buckle up as I will walk you through the complete introduction to JRC4558 covering datasheet, pinout, features, alternatives, and applications. Let’s jump right in.

Greeting, and welcome to the next tutorial of our raspberry programming tutorial. In the previous tutorial, we learned how to build a smart attendance system using an RFID card reader, which we used to sign in students in attendance in a class. When it comes to building a face-recognition program on a Raspberry Pi, this tutorial will show you how. Two Python programs will be used in the lesson, one of which is a Training program that analyzes a collection of photographs of a certain individual and generates a dataset. (YML File). The Recognizer application uses the YML script to detect a face and afterward utters the person's name when the face is detected.

Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share my knowledge about Introduction to 74HC245. 74HC 245 is a eight (8) bit transceiver. It has three (3) output states. 74HC-245 is designed for a-synchronous transfer of data between different data buses. The external timing requirement can be reduced by the implementation of control function. You should also have a look at Introduction to 74HC595.
There are two internal amplifiers in 74HS 245. They are named as A and B. Data is transferred from A amplifier to B amplifier and vice versa. Hence two way communication is done in 74HC-245. This communication depends upon the logic level on the direction control input (DIR). Out enable pin (OE) is used to ...
Hello Guys! I hope you’re well today. Happy to see you around. Thank you for clicking this read. In this post today, I’ll walk you through the Introduction to TL082.The TL082 is a wide bandwidth dual JFET input operational amplifier. High speed, low cost this device comes with internally trimmed offset voltage. It is available with a fast slew rate, a large gain bandwidth, and a low supply current.
I suggest you buckle up as I’ll discuss the complete Introduction to TL082 covering datasheet, pinout, features, and applications. Let’s get started:

Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to give you a detailed Introduction to ULN2003. We will also discuss the ULN2003 Datasheet, Pinout, Circuit Diagram & Proteus Simulation. If you have ever controlled any motor (i.e. DC Motor, Stepper Motor etc.) with a microcontroller (i.e. PIC, Arduino etc.), then you must have heard about drivers. Why do we need to use drivers? We use drivers (to control motors) because of two reasons.
First: Microcontrollers operate at 5V while motors operate at different voltages (5V, 12V, 24V etc.).
Second: Motors are Inductive loads thus they produce back emf, which may damage your microcontroller permanently (if not handled correctly).
Because of these two reasons, we have to use the driver in between t ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to explore my knowledge about Introduction to LM317. It is basically a positive voltage regulator having three terminals. It can a supply a current more than 1.5A and voltage in a range of 1.25V to around 37V. You should also have a look at this LM 317 Calculator.
For the adjustment of output voltage only two external resistors are required. It has improved standards of line regulation as well as load regulation. Full overload protection e.g. current limiting, area protection can be achieved using LM317. If its adjusting terminal is disconnected, even then all of the protection circuits will work properly. We can also use LM317 as precision current regulator ...
Hello friends, I hope you all are doing great. In today's tutorial, we are gonna have a look at detailed Introduction to HC-06.
