The Internet of Things ( or IoT) is a network of interconnected computing devices such as digital machines, automobiles with built-in sensors, or humans with unique identifiers and the ability to communicate data over a network without human intervention.
Hello readers, I hope you all are doing great. In this tutorial, we will learn how to send sensor readings from ESP32 to the ThingSpeak cloud. Here we will use the ESP32’s internal sensor like hall-effect sensor and temperature sensor to observe the data and then will share that data cloud.
What is ThingSpeak?
Fig. 1: ESP32 ThingSpeak
It is an open data platform for IoT (Internet of Things). ThingSpeak is a web service operated by MathWorks where we can send sensor readings/data to the cloud. We ...

Hi Friends! Hope you are doing great. Today, I am going to give you a detailed Introduction to Arduino Uno. It is a microcontroller board developed by Arduino.cc and is based on Atmega328 Microcontroller. The first Arduino project was started in Interaction Design Institute Ivrea in 2003 by David Cuartielles and Massimo Banzi with the intention of providing a cheap and flexible way for students and professionals to learn embedded programming.
Arduino UNO is a very valuable addition in electronics that consists of a USB interface, 14 digital I/O pins(of which 6 Pins are used for PWM), 6 analog pins and an Atmega328 microcontroller. It also supports 3 communication protocols named Serial, I2C and SPI protocol. You should also have a look at this vid ...
Hello friends, I hope you all are doing great. In today's tutorial, I will share a Proteus Library of another embedded module i.e. NodeMCU. NodeMCU is a microcontroller board and if you are new to this board, you should read Introduction to NodeMCU to get your hands dirty. NodeMCU is not present in the components library of Proteus and using this library you can easily simulate NodeMCU in Proteus.We can't add WiFi and BLE capabilities to our module in the Proteus software, that's why it will just perform the basic functions i.e. sensors interfacing, PWM, I/O control etc. So, you can use it for simple code testing and can also use it to design circuit diagrams of your projects.So, let's have a look at How to download NodeMCU Proteus Library and simulate it:
NodeMCU Library for ProteusFirst ...
Hello friends! I hope you will be absolutely fine and having fun. Today, I will give you an elaboration on Introduction to SG3524. I have already shared articles on Introduction to 74HC245, 74HC595, CD4051, L293D, L298, LF351 and LF411. You should also go through all of these tutorials in order to have a better understanding. SG 3524 consists of all the important functions necessary to design inverters.
Moreover, using SG-3524 we can also design regulation power supplies as well as switching regulators. This all design is based on a single chip. High power applications can also be controlled through this device. SG-3524 is especially designed for voltage doublers without transformers, transformer coupled DC to DC converters. Their design was als ...
Hi Folks! I welcome you on board. Thank you for clicking this read. Happy to see you around. In this post today, I’ll walk you through the Introduction to CA3140.The CA3140 is a general-purpose op-amp that comes with a 4.5MHz frequency. It is a BiMOS Operational Amplifier incorporated with MOSFET Input/Bipolar Output that extends the advantages of both… high-voltage bipolar transistors and high-voltage PMOS transistors on a single integrated chip.
I suggest you read this post all the way through as I’ll detail the complete Introduction to CA3140 covering datasheet, pinout, features, and applications. Let’s jump right in.

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 ...
Hello everyone! I hope you all will be absolutely fine and having fun. Today I am going to given elaboration on Introduction to L293D. L 293D is basically a high current dual motor driver/controller Integrated Circuit (IC). It is able to drive load having current up to 1A at the voltage ranging from 4.5V to 36V. Motor driver usually act as current amplifier because they receive a low current signal as an input and provides high current signal at the output.
Motors usually operates on this higher current. L-293D has to builtin H-Bridge driver circuits and is able to control two DC motors at a time in both clockwise and counter clockwise direction. It has two enable pins and they should be kept high in order to control the motor. By changing the p ...
Hello everyone! I hope you will be absolutely fine and having fun. Today, I am going to explain all of you about Introduction to 74HC595. It is basically a shift register. It has an ability to store and to shift the data of 8 bits. First of all the data is written on the register serially and then it goes to the storage register. All of the output lines are controlled by this register.
74HC595 register is a very high speed device based on Complementary Metal Oxide Semiconductor (CMOS). 8 bit data register receives the data from the input DS. This data is then transferred from the input shift register to the output shift register. 74HC595 has a vey wide range of applications in daily life. It can be used as serial to parallel data converter, can ...
