Hello friends, hope you all are fine and enjoying life. Today's post is about removing a small error named as Recognition Failed in EasyVR, which I encountered while working with EasyVR shield with Arduino UNO. I have posted a complete project on EasyVR shield around a year ago in which I haven't mentioned this error because at that time I didn't encountered it. But today while working with EasyVR shield, I encountered this problem so I thought to share it with you guys.
EasyVR shield is a voice recognition module which is used for recognizing voices and operating accordingly. Using this module, one ca quite easily control anything using voice. In the previous project, I have controlled a robot using voice commands like when I say Forward then it ...
Hi Guys! Welcome you on board. Happy to see you around. In this post today, I’ll detail the Introduction to LM2596.LM2596 is a step-down voltage regulator, also known as a buck converter, mainly used to step down the voltage or to drive load under 3A. It carries remarkable load and line regulation and is available in fixed output voltages including 3.3V, 5V, and 12V. It also comes with a customized output version where you can set the output voltage as per your requirement.
Just stay with me for a little while, as in this post I’ll walk you through the Introduction to LM2596 covering the datasheet, pinout, features, and main applications of this tiny device. Let’s jump right in.

Hey Guys! Hope you’re well today. Happy to see you around. In this post today, I’ll detail the Introduction to 1n4734a.The 1n4734a is a Zener diode used as a low-current voltage regulator. It is composed of silicon material and is employed as a shunt regulator in many applications. This Zener diode conducts the current in both directions in contrast to a normal diode that conducts in one direction only i.e. conducts in forward biased condition only.
I suggest you read this post all the way through, as I’ll be discussing the datasheet, pinout, features, and applications of 1n4734a. Let’s jump right in.
Introduction to 1n4734A
The 1n4734a is a Zener diode used in clipping circuits with a high power rating.
It comes in the DO-41 package and is used as a low-current voltage regulat ...
Hello Guys! I welcome you on board. Happy to see you around. In this post today, I’ll walk you through the Introduction to Arduino MKR GSM 1400.
The Arduino MKR GSM 1400 is a microcontroller board that is based on the SAMD21 microcontroller. This device connects with a cellular network for developing communication. This GSM board is a one-stop solution for developing your sensor network or you can use it as a device sending a text message about the occurring of certain events remotely.
A module from u-blox, the SARA-U201 (which is a power chipset that activates using multiple cellular range bands) is responsible for GSM / 3G connectivity inside the device.
I recommend you read this post till the end as I’ll detail the complete Introduction to A ...
Hello everyone, we are back with a new project and we hope you all are doing well. In this article, we will discuss a project named Smart Irrigation System using Arduino UNO. We will use different sensors to measure the environmental and crop parameters which are responsible for good production. We will also make the water pump system automatic which will open the water valve automatically according to the soil moisture of the crop.
We will discuss all points and concepts briefly in this article and also provide a Proteus Simulation to observe how it will work in the real world. Complete fully explained code and simulation are also provided below as you go ahead in this article. You can download it from there.

Hello friends, i hope you all are fine and enjoying in life. On a friends request, today i am going to share a new tutorial which is 'Getting Started with Arduino Software'. Previously i have uploaded a large no of project tutorials made on 555 timers and some MATLAB based Simulations. Now we are going to touch the next level and from now on we will work on mostly projects containing Arduino microcontroller.
To get started with Arduino microcontroller, we first need to learn the operating software of Arduino microcontroller. This tutorial is very informative and i will be using Arduino software 1.0.5. It is a very basic level software and very easy to learn. IF you have already worked on Arduino software then you don't need to go through it. This ...
Hello Everyone! Hope you’re well today. In today's tutorial, we will have a look at D13005K NPN Transistor. We will also study D13005K Datasheet, Pinout, Power Ratings, Equivalents & Applications. As its an NPN transistor, so major charge carriers are electrons. D13005K is mainly employed for switching and amplification purpose.
Let's first recall NPN transistors: NPN transistor consists of 3 terminal, named as:
Emitter.
Collector.
Base.
If we provide voltage > 0.7V at base terminal, NPN transistor gets forward biased & starts conducting. If Base voltage D13005K NPN Transistor:
D13005K NPN Transistor
D13005K is a bipolar NPN transistor, mainly used for amplification and switching purposes.
It contains three layers where two n-doped layers surround one p-doped la ...
Hi Guys! Hope you’re well today. I welcome you on board. In this post today, I’ll walk you through the Introduction to Arduino Nano 33 BLE.
Arduino Nano 33 BLE is an advanced version of Arduino Nano board that is based on a robust and powerful processor the nRF52840 from Nordic Semiconductors, a 32-bit ARM® Cortex™-M4 CPU. It comes with a crystal oscillator frequency of around 64MHz. It features 32 times bigger program memory than the Arduino Uno board, helping you store programs with much larger memory. With this device, you can produce a lot more variable as it comes with RAM that is 128 times bigger than the RAM of Arduino Uno.
Before you move further, I recommend you read this article on the Introduction to Arduino Nano which we have publish ...
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 ...
Hi Friends! Hope you’re well today. I welcome you on board. Happy to see you around. In this post today, I’ll walk you through the Introduction to SR5100.
The SR5100 is a Schottky diode used to generate extremely fast switching. It is also called a hot-carrier diode and is protected against overvoltage. It comes with a high surge current capability and low forward drop voltage. It contains a forward rectified current around 5 A and terminal resistance around 28 C/W.
