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 readers, I hope you all are doing great.
ESP32 is a powerful chip for Internet of Things applications. This tutorial is also based on one of the ESP32 applications in the field of IoT.
Project Overview
In this tutorial, we will learn how to update LCD display with new data or input using a web server created with ESP32.
Fig. 1
To achieve the target, we will be using an HTML (Hypertext Markup Language) form to provide web input and then update the text displayed on LCD. The values or input received from the webserver will be further stored inside a variable in the code for further use (to display on LCD).
We have already posted a tutorial on LCD (Liquid Crystal Display) interfacing with ESP32. In that tutorial, we demonstrated how to displa ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to share a detailed Introduction to MC34063. It's normally required for the construction of DC to DC converters. MC34063 has a high current output switch, Pulse Width Modulation (PWM) controller with current limiting, compensated reference of internal temperature, a comparator and a driver.
For the inverting, boost and buck applications there is no need of a huge complicated external components, instead they can be performed using minimum external components. MC 34063 operates properly in the temperature ranging from 0 to 70 degree celsius. MC34063 ha s wide range of applications in real life e.g. portable equipment, Human Machine Interface (HMI), test and m ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today, I am going to give a detailed discussion on Introduction to LM318. LM 318 is basically a high speed Operational Amplifier (Op-amp). It provides higher slew rates and wide range of bandwidth. LM-318 has processing speed 10 times higher than the common operational amplifier. It has unity gain frequency compensation. External components are not required for its operation.
Feed forward compensation increases the slew rate up to 150 V/us for inverting applications. It also doubles the bandwidth as compared to the earlier. In LM 318, in order obtain the high stability level we overcompensation can be used with amplifier. LM 318 setting time can be reduced by adding an extern ...
Hi Guys! Hope you are getting along with life pretty well. I always strive to keep you updated with most valuable information related to engineering and technology.

2n7002 is an N-Channel MOSFET which is mainly d ...
Hi Guys! I welcome you on board. In this post today, we’ll discuss the KSC1845 NPN Transistor. We will have a look at the KSC1845 Datasheet, Pinout, Power Ratings, Equivalents & Applications in detail. As it's an NPN transistor, electrons are the majority charge carriers and thus play a major role in conductivity. KSC1845 is mainly used for fast-switching and amplification purposes.NPN transistor carries 3 terminals, known as:
Emitter
Collector
Base
If the applied voltage at the base terminal exceeds 0.7V, it will forward bias this NPN transistor and the current will start to flow from Collector to Emitter. If the base voltage is less than 0.7V, KSC1845 will remain in the reverse-biased state.
I suggest you buckle up as I’ll discuss the KSC1845 ...

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 ...
