Control Flow Statements – Part 2

Hello everyone, in this article, I am writing about “Switch case in C” which is another type of control flow statement. If you come here looking for if - else, then go to this article. Switch Case in C The syntax of “Switch case” in C is- switch (expression) { case 1:...

If-Else in C

Control flow statement in C (If - Else) – Part 1 This article is all about the control flow statement in C (If - else). It means if you want to control the certain execution of the program according to the condition described by you. For example, you want to check if...

Serial Terminal Using NodeJS

In this tutorial, we will describe a small project in NodeJS viz Serial Terminal using nodeJS. I am assuming that you have basic knowledge of nodeJS. This project can be done with some simple procedure. This is also useful for communicating with the Arduino or any...

Control Arduino using Node JS

As the title says, this tutorial will teach you how to control your Arduino by Rpi, Computer or Laptop. I am not a big fan of the Windows so I will use Ubuntu (Linux). Basically, Rpi also uses Linux so there will be the same steps for Rpi as well. For windows though,...

Functions in C/C++

What are the functions in C and why should we use them? Suppose you have to write a code in which you have to find out the sum and difference of two numbers three times. Well, it’s very simple to do that but now you have to write the same code three times. To make...

Loops in C

What are the loops in Programming and what are they use for? Suppose you have given a task to print your name 5 times. Simple right? You can just print your name 5 times in the main function. But in programming, you don’t want to write the same code for doing the same...

Connect NodeMCU to Server

Introduction Hello everyone, this another post on NodeMCU. In this post, I am going to write about how to connect and send the request from your esp client to the server. If you have little idea about NodeMcu or Esp8266, you can go back to previous posts. Let’s get...

Connect Arduino with Computer using HC05 Bluetooth Module

At some point in time, you may want to connect and send some data to your computer from Arduino. In this article, I am going to tell you how to connect your Arduino with your computer using over bluetooth using an HC05 bluetooth module. For this little project, we...

I2C Communication Introduction

I2C Communication W have already discussed UART and SPI before. Next, up is I2C communication often pronounced as I-squared C or I-2-C communication. This is a protocol designed by Phillips in ’90s for communicating between devices inside the TV set. I2C simple, short...

Arithmetic Operation in C

Hello there, in the previous tutorial of datatypes, we have discussed some data types in C. In this post, we are going to use some of those concepts here. Also, we are going to understand arithmetic operators and operation in C. Problem Statement The problem statement...

SPI of AVR

SPI of AVR In the previous article of spi introduction, you have got the idea about the basics of SPI communication. Let’s implement  SPI communication in Atmega 16 of AVR. Registers of SPI Till now, you must have got an idea of how things in the embedded world work....

GPIO Control by ESP as Web Server-IOT

Hello there folks, welcome to the second part of the home automation ESP 8266 tutorial. In the previous post, we are able to set up our ESP and burned our Arduino firmware into that chip. Well in this post, I will show you how to control the GPIO through Wifi. Let’s...
