Introduction to Arduino MKR WiFi 1010
The Arduino MKR WiFi 1010 is a powerful microcontroller board that allows for easy and efficient control of devices remotely. It is an update to the previous MKR1000 model, with improved features and capabilities. This board is designed specifically for IoT (Internet of Things) projects, making it a popular choice among hobbyists and professionals alike.
One of the most notable features of the Arduino MKR WiFi 1010 is its built-in WiFi module. This allows for wireless connectivity, enabling users to remotely access and control their devices from anywhere with an internet connection. The board also has a low power consumption mode, making it ideal for battery-powered applications.
In addition to its WiFi capabilities, the MKR WiFi 1010 also has a powerful processor – the SAMD21 Cortex-M0+ – which operates at 48MHz. This allows for fast data processing and real-time communication with other devices.
Another advantage of using the Arduino MKR WiFi 1010 is its compact size and low cost. It measures only 67.64mm x 25mm, making it one of the smallest boards in the Arduino family. Despite its size, it packs impressive features that make it suitable for various projects without breaking the bank.
Furthermore, setting up and programming this board is relatively easy even for beginners. It can be programmed using either the Arduino IDE or through an online editor called Web Editor - both of which offer a user-friendly interface and extensive documentation.
What is a Web Server?
A web server is a computer or program that hosts websites and serves content to clients over the internet. It acts as the backbone for any website, allowing users to access web pages and interact with them. In simple terms, a web server is like a virtual storage unit that contains all the files and data necessary for a website to function.
The concept of a web server may seem daunting at first, but it is actually quite straightforward. When you type in a URL into your browser's address bar, you are essentially sending a request to the web server. The server then processes this request and sends back the relevant web page to your browser, which then displays it on your screen.
Web servers use HTTP (Hypertext Transfer Protocol) as their communication protocol. This allows for the transfer of data between clients (users) and servers over the internet. However, there are different types of web servers based on their functionality and features. One common type is an application/web server that runs programs and scripts written in various languages such as PHP or Python.
Setting up the Arduino MKR WiFi 1010 as a Web Server
Setting up the Arduino MKR WiFi 1010 as a Web Server is an essential step in controlling devices remotely using the Arduino MKR WiFi board. A web server allows you to create a website that can be accessed over the internet, and with the help of the WiFi connectivity on your board, you can control your connected devices from anywhere in the world.
To set up your Arduino MKR WiFi 1010 as a web server, follow these steps:
Step 1: Connect Your Board to Your Computer
The first step is to connect your Arduino MKR WiFi 1010 board to your computer using a USB cable. This will power up your board and allow it to communicate with your computer.
Step 2: Download and Install the Required Software
Next, you need to download and install two software programs - Arduino IDE and PuTTY. The Arduino IDE is used for programming the board while PuTTY is a terminal emulator that will help us communicate with our web server. You can download both of these software programs for free from their respective websites.
Step 3: Set Up Your Network Connection
Before we can start configuring our web server, we need to make sure that our network settings are correct. This includes setting up an IP address for our board and connecting it to our local network.
Controlling Devices Remotely using HTML and JavaScript
One of the most exciting features of the Arduino MKR WiFi board is its ability to control devices remotely using HTML and JavaScript. This allows users to operate their connected devices from anywhere in the world, as long as they have an internet connection.
To begin controlling devices remotely with this board, you will first need to set up a web server on your Arduino MKR WiFi. This can be easily done by following the instructions provided in the official Arduino documentation. Once your web server is up and running, you can start writing code in HTML and JavaScript to send commands to your connected devices.
HTML (Hypertext Markup Language) is used for creating web pages and providing structure and content to them. It allows users to create interactive elements such as buttons, text fields, and drop-down menus that can be accessed through a web browser. In our case, we will use HTML elements to control our devices remotely.
JavaScript is a programming language that runs on web browsers and lets you add dynamic effects or functionality to your web pages. With JavaScript, we can write code that sends instructions from our webpage via the internet to our Arduino MKR WiFi board.
Now let's take a look at how we can use these languages together to control devices remotely with the Arduino MKR WiFi board:
The first step is designing a user interface (UI) for controlling our devices. This involves creating an HTML page with buttons or other input elements that represent various commands for our connected devices.

The Internet of Things (IoT) is a rapidly growing technology that connects everyday objects to the Internet, allowing them to communicate and share data with each other. This has revolutionized the way we interact with devices, making our lives more convenient and efficient. One such device is the Nodemcu, which is a low-cost open-source development board that can be used for IoT projects.
In this blog post, we will introduce you to IoT and Nodemcu, and show you how to create your own smart water level indicator using this versatile board.
What is IoT?
IoT refers to the network of physical devices embedded with sensors, software, and connectivity capabilities that enable them to collect and exchange data over the Internet without human intervention. These devices can range from simple household appliances like light bulbs and refrigerators to complex industrial machines.
The concept behind IoT is to connect these devices so they can gather data from their surroundings and use it for various purposes. This could include monitoring temperature, humidity, air quality, energy usage, etc., in real time. By analyzing this data, these devices can make intelligent decisions or send alerts when certain conditions are met.
Understanding the concept of a Smart Water Level Indicator
A Smart Water Level Indicator is a device that is used to monitor and display the level of water in a tank or reservoir. It provides accurate and real-time information about the water level, making it an essential tool for managing water usage and preventing overflow.
The concept behind a Smart Water Level Indicator is based on the principle of buoyancy. As water fills up the tank, it exerts pressure on the sensor attached to the indicator, causing it to rise. This change in position is detected by the microcontroller, which then translates it into a readable form for display.
One of the main advantages of using a Smart Water Level Indicator is its ability to accurately measure even small changes in water levels. This makes it particularly useful for applications such as rainwater harvesting systems, where every drop of water counts.
In addition to providing real-time information about water levels, some advanced versions of smart indicators also come with features like setting alarms for low or high levels and remote monitoring via mobile apps.
Now that you have a basic understanding of what a Smart Water Level Indicator does, let's take a closer look at how you can create your own using Nodemcu - an open-source hardware platform based on ESP8266 Wi-Fi Module.
Materials needed for the project
To successfully create your own smart water level indicator using Nodemcu, you will need the following materials:
