10 Most Useful Arduino Projects

Arduino is an open-source platform used for building electronics projects. It consists of a microcontroller board and software that allows users to create programs for the board. Arduino has gained popularity among hobbyists and makers because it is easy to use and has a wide range of applications.

Maze Solver Robot

This robot is designed to solve mazes. It uses IR sensors to navigate the maze and then calculates the shortest path from start to finish. The robot is able to solve any maze with more than one path and also can find its way out of a loop. The design is simple and you can easily modify it to solve your own maze.

Portable Humidifier

It’s no secret that the air indoors can be pretty dry, especially during the winter. And while there are a lot of ways to combat dry air, one of the most effective is to use a humidifier. A humidifier increases the moisture in the air, making it more comfortable to breathe and helping to prevent things like nosebleeds, static electricity, and cracked skin.

But not all humidifiers are created equal. For example, portable humidifiers are a great option if you want something that you can easily move from room to room. And if you’re looking for something a little more high-tech, there are even humidifiers that come with built-in sensors that help to automatically regulate the humidity in your space.

This portable humidifier is a device that adds moisture to the air. It is often used to improve the air quality in a room or office.

The device turns on the humidifier when humidity is detected by an Arduino-controlled sensor. It’s a fun project that isn’t difficult to put together.

Arduino Plant Watering System

An automatic plant watering system is a system that waters plants automatically. It uses sensors to detect when the soil is dry and then waters the plants accordingly.

The Instructable team will show you how to build a plant watering system that runs on Arduino power. You can get each of the components they used by following the links they provide. From hardware to code, every step of building this system is spelled out.

Drawing Robot

Drawing robots are one of the more interesting projects you can work on with an Arduino board. They’re simple to build – even if you’ve never tried a project like this before – and very precise. Plus, they’re cheap to make.

All you need is an Arduino UNO, some wire, screws, plywood, bearings, and a 3D printer. You can easily find all of these materials online or at your local hardware store. If you’re looking for an engaging project that’s also fairly easy to build, then a drawing robot is a great option.

Speedometer

Have you ever wondered how fast your car was going? Or how quickly that tennis ball was rolling across the court? If you’re interested in finding out the speed of moving objects, then this speedometer project is for you! With just a few materials – including an Arduino Nano, an ultrasonic sensor, and an LED – you can easily build this handy device.

The speedometer measures the distance of an object and displays its speed on an LCD screen. The LED will blink faster or slower depending on the object’s distance. Plus, if the object is moving in the opposite direction, the speed will be displayed with a negative sign.

TV Remote Control

Do you ever lose your remote control? With this project, you can build your own! This TV remote control is made with an Arduino Nano and a few other simple components. It uses an IR LED to send signals to the TV, changing the channel, volume, and more.

With just a little soldering experience, you can put together this handy little device. All you need is an Arduino UNO, some wire, and a 3D printed case. The different components come together to create a neat little package that you can use to control your electronic devices.

Smart Dustbin

A smart dustbin is a bin that uses sensors to detect when it is full and sends a message to the owner to empty it. This project is perfect for anyone who wants to create a more efficient way of managing their trash.

The Arduino-based project with an ultrasonic sensor is straightforwardly explained step by step, with code and parts URLs provided, and the developer is helpful with questions.

Basement Flood Alarm

A basement flood alarm is a device that alerts you when there is water in your basement. This can be useful if you live in an area prone to flooding or if you have a sump pump that occasionally fails.

The compact monitor consists of an Arduino Uno, a moisture sensor, and two buzzers. The moisture sensor is placed in the basement in an area where water would pool first in the event of a flood. The Arduino is programmed to constantly check the sensor’s readings. If the humidity level rises above a certain threshold, it activates one of the buzzers to sound an alarm. The second buzzer is connected to a rain gauge, and it will sound if more than an inch of rain falls in a day. That way, you’ll have some warning even if you’re not home when the flooding starts.

Robotic Arm

Arduino has been used for a wide range of projects, from simple tasks like blinking an LED to more complex tasks like controlling a robotic arm. A robotic arm can be used for a variety of purposes, such as manufacturing, construction, and even surgery.

The Arduino robotic arm project is one of the more popular Arduino projects. It consists of an Arduino board, two servo motors, and a few other components. The project can be adapted to a wide range of applications, such as controlling a robotic arm to pick up and move objects.

With a little ingenuity, the project can be used to create all sorts of automated devices. For example, you could use it to build an automatic feeder that dispenses food when your pet is hungry.

Or you could use it to make a simple security system that sounds an alarm when someone tries to break into your home. The possibilities are endless.

Self-balancing Robot

A self-balancing robot is a robot that can maintain its balance on two wheels. It uses sensors and motors to keep itself upright and can move in any direction.

The project consists of an Arduino board, motors, and a few other components. The sensors are used to detect the tilt of the robot and the motors are used to correct the tilt.
