Welcome to the next tutorial of our Raspberry Pi programming course. Our previous tutorial taught us to make a button-controlled "music box" that plays different sounds depending on which buttons are pressed. In this lesson, we will configure our raspberry pi for voice control.
What will you learn?
Like the Amazon Echo, voice-activated gadgets are becoming increasingly popular, but you can also construct your own with a Raspberry, a cheap USB mic, and some appropriate software. Simply speaking to your Raspberry Pi will allow you to search YouTube, view websites, activate applications, and even answer inquiries.
What will you need?
Because the Raspberry Pi lacks a soundcard or audio port, this project requires a USB microphone or a camera with a ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give you an elaboration on Introduction to LM2575. LM2575 is specially designed to simply the design of switching power supplies. It can be done by providing all the necessary active functions required in Integrated Circuit (IC) for step down regulators. LM-2575 can deliver load current of around 1A along with the good line regulation as well as load regulation. LM 2575 has different builtin functions e.g. frequency compensation, cycle by cycle current limiting, oscillator with the fixed frequency and a lot more.
LM-2575 has many amazing features i.e. it can reduce the heat sink size due to its higher efficiency parameter. In some cases even heat sink is ...
Hello friends, I hope you all are doing great. In today's tutorial, I am going to share new Magnetic Reed Switch Library for Proteus. We are quite proud to share it as its not been designed before. Our TEP Team has designed it and I think they need a little appreciation. :P You can interface it with any Microcontroller like Arduino, PIC or 8051 Microcontroller etc.
As Proteus is a simulation software so we can't produce magnetic field in it. That's why, we have placed a TestPin and when you provide HIGH Signal to that TestPin then it will act as it has magnet around. Similarly, if you provide LOW Signal to that TestPin then it will behave normal and will sense no magnet around. Rite now, we have just designed two Magnetic Reed Switches but soon we ...
Hello friends, I hope you all are fine and having fun with your lives. Today, I am going to share a very basic and introductory tutorial named How to use Arduino Serial Read. I am sharing this tutorial because I am getting a lot of emails in which users normally ask about basic Arduino tutorials as they are very new to them. So, I thought of sharing this very basic Arduino tutorial in which we are going to have a look at how we can use the Arduino Serial Read command.
I selected this tutorial as my first tutorial in this list of Arduino basic tutorials because learning to use Serial port is very necessary as it's one of the best troubleshooting tools for your code. I have also given a Proteus Simulation in which I have received the incoming data f ...
Hey Guys! Hope you are getting along with life pretty well. Welcome you onboard. Today, I'll unlock the details on the Introduction to Arduino Micro. It is a Micro board, based on the ATmega32U4 microcontroller and comes with built-in USB, making it easily compatible with the computer.
Arduino Micro, as the name suggests, is the smallest board in the Arduino Community. It is comparable to its counterparts like Arduino Nano and Arduino Promini.
In this tutorial, I'll discuss each and everything related to Micro board including its main features, pinout, pin description, the software used and applications. Let's dive in and explore everything you need to know about this tiny board.

Hi everyone! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to P6KE220A.The P6KE200A is a transient voltage suppressor (TVS) diode that uses clamping action to provide circuit protection against overvoltage. It is widely used in low-voltage supplied ICs and MOS technology due to its quick response to transient overvoltages. For P6KE200A the clamping voltage is 246V and the breakdown voltage is ranged from 190V to 210V.
I suggest you read this entire post till the end as I’ll detail the complete introduction to P6KE200A covering datasheet, pinout, features equivalents, and applications of this component P6KE200A.

Hello Everyone! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to Arduino USB Host Shields.
With Arduino USB host shield you can interface the USB device to your Arduino board. This USB host shield is based on MAX3421E which is mainly known as the USB host controller that contains the analog circuitry and digital logic required to apply the USB full speed peripheral to USB specifications rev. 2.0.
Moreover, this shield is compatible with TinkerKit which projects you can plug this TinkerKit module with the Arduino Boards.

Hello friends, I hope you all are happy, healthy, and, content. Today, our discussion is all about "Diodes". Whoever has been a science student, knows about diodes. Although it seems to be a tiny component of a circuit, apparently it is true but it has a lot of complexities or you can say, it's a storm in a teacup. You might have read a lot about diodes in physics, in today's discussion we would be moving step by step into the pool of diodes from definition to working of diodes, their types, and then lastly its applications. Let's get started!
Diode Definition
First things first, Let's define diode,
A diode is a basic discreet electronic component made up of semiconductor material, used in electronic circuits, which allows unidirectional c ...
Hello Friends! I aspire you a very happy life. Whenever you come over and visit our site, we feel happy to keep you updated with relevant information that can help resolve your questions and queries. Most of the hobbyist and students take interest in electronic devices and components that are the building blocks of electronic projects. Today, I am going to uncover the details on the Introduction to DG408. It is a multiplexer, also known as data selector, that comes with 8 channel input, in which of one the eight inputs is connected to the common output for the transmission of data over network in a specific bandwidth and time. It is an ideal choice for audio signal routing and single supply system. I'll discuss each and everything related to this ...
