Read MoreUsing the WiFi Mode with ESP32
ESP32 microcontroller can connect to the internet and use the wifi. It can be used to see the network details of the available networks. It can also be used for advanced functions such as changing the MAC address of ESP32. In this article, using three different examples, the programs using the wifi with ESP32 are given. In example 1, a C program is used to scan the wifi networks available and the details are displayed. In example 2, the wifi connection is established by giving the SSID details, and in example 3, the current Mac address of ESP32 is seen ...
Read MoreUsing NoSQl Database with IOT
NoSql databases are those databases that do not store the data as data is stored in relational databases. Most of the data that is used in real life is often unstructured. These NoSQL databases provide an easy way to store this unstructured data by using key-value pairs. In this article, a NoSQL database called Firebase is used with a C program that controls the IOT circuit. The article presents the writing of the values to the firebase and getting the values from the firebase in real time and using those for controlling the circuit components. Connecting the Firebase, Wifi, C ...
Read MoreGo vs Java
Go and Java are two popular programming languages used for developing different types of applications. While both languages have their unique features and advantages, there are some key differences between them that developers should consider when deciding which language to use for their projects. In this article, we'll explore the differences between Go and Java in terms of syntax, performance, concurrency, and more. Go Java Syntax Go has a simpler and more concise syntax compared to Java. Go has fewer keywords and syntax rules, making it easier for developers to read, write and maintain code. ...
Read MoreGolang program that removes duplicates, ignores order
When working with slices in Golang, it's common to need to remove duplicate elements from the slice. While there are many ways to do this, one approach that can be particularly useful is to remove duplicates while ignoring the order of the elements. This can be useful, for example, when you want to compare two slices for equality without caring about the order of the elements. In this article, we'll explore a simple Golang program that removes duplicates from a slice while ignoring the order of the elements. We'll break down the program step by step to explain how it ...
Read MoreThings Needed to start IOT
IOT ie. The Internet of Things refers to all those devices that can communicate over the Internet and can be made accessible or connectable by anybody and from anywhere in the world. IoT is already being used or has been seen implemented in different forms such as in Smart cars and watches, Smart homes, Smart irrigation systems, Smart cities, etc. To start learning IOT, first, it is important to learn about the things that are needed to make circuits. There are some simulators available to make the beginner of IOT learn these concepts without even having the IOT devices available. ...
Read MoreGenerate UUID in Golang
Universally Unique Identifier (UUID) is a 128-bit value that is used to uniquely identify objects or entities. UUID is widely used in computer systems for generating unique IDs for objects, documents, and data records. In Golang, we can generate UUID using the "github.com/google/uuid" package. Installing the "github.com/google/uuid" Package Before we can generate UUID in Golang, we need to install the "github.com/google/uuid" package. To install this package, run the following command in the terminal − go get github.com/google/uuid Generating UUID in Golang Once we have installed the "github.com/google/uuid" package, we can use the "uuid" package to generate UUIDs. Here's an ...
Read MoreColor Shades using RGB Led
To learn about RGB led and the difference between single-color LEDs, it is important to make a circuit using a microcontroller such as ESP32 or Arduino and RGB led. Then it is important to manage that circuit using a program. There are some simulators available to make the beginner of IOT learn such concepts without even having the IOT devices available. However, to get real results, using the circuit components and making the actual circuit is important. In this article, using two different examples, the way to use the RGB led is given. In example 1, the actual circuit using ...
Read MoreGetting the current date and time with timestamp in local and other timezones in Golang
In Go, it's easy to work with dates and times using the time package. This package provides a set of functions and types for working with dates and times, including the ability to get the current date and time with a timestamp in local and other timezones. In this article, we'll explore how to get the current date and time with a timestamp in local and other timezones using Go. Getting the current date and time with timestamp in local timezone To get the current date and time with a timestamp in the local timezone, we can use the time.Now() ...
Read MoreGolang program that uses structs as map keys
Golang is a powerful programming language that provides a variety of features to work with structured data. One of these features is the ability to use structs as keys in maps. In this article, we will explore how to write a Golang program that uses structs as map keys. What is a Struct? In Golang, a struct is a composite data type that groups together zero or more values of various types. Structs are used to create more complex data types that can represent a range of objects. A struct is defined using the type and struct keywords, followed by ...
