Top 7 Arduino Projects Ideas & Topics For Beginners

Arduino is an open-source electronics platform. The key highlight of Arduino is that it focuses on easy-to-use software and hardware for interactive project development. 

Since it is an open-source platform, Arduino has a huge fan following. Students, aspiring programmers, and professional developers from all across the world actively contribute to enriching the Arduino community. The best part – these contributions are easily accessible to anyone who wishes to explore and experiment with the platform.

Arduino boards are exceptional tools that can read inputs and convert the same into an appropriate output. For instance, if an Arduino board reads a light blinking on a sensor, it will activate or deactivate the device. You can control the actions of an Arduino board by sending a set of instructions to the microcontroller located on the board. Also, to use Arduino hardware for creating an Arduino project, you must be well-versed with the Arduino language and the functioning of the Arduino IDE.

Today, we’ll talk about seven wonderful Arduino project ideas that you can toy with – you can either try to recreate these Arduino projects, or you can modify them into your unique creation.

So, without further ado, let’s get started!

Top Arduino Project Ideas for Beginners

1. LED Matrix Lamp

This Arduino-based project is not only beautiful but practical as well. The exciting thing about this project is that you will make it by using hot glue sticks. Other requirements for the project include an LED strip, Arduino Nano R3, resistors, capacitors, mini DC-DC step-down converter volt regulator, and DC power socket, to name a few. Also, you need a 3D printer to print the case.

Assembling the project is relatively simple. Once you assemble the lamp section, you need to add the glue sticks and arrange the wiring.

2. Mega Digital Chessboard

If you are a chess fanatic, this is the project for you!

In this project, you’ll be developing a mega digital chessboard. To make this, you will need a TFT LCD touch screen display and an Arduino Mega 2560 board. Apart from these two primary materials, you will also need a buzzer, resistor, and a soldering iron. You can also get more creative by using a 3D printer to print a pretty case for the chessboard.

As for the game, the standard rules apply. You can rotate the chessboard and make your move using drag and drop motions.

3. LED Controller

One of the easiest Arduino projects you could ever get your hands on, the LED Controller is designed to control electronic devices using smartphones.

The components required for this project are Arduino UNO and Genuino UNO, LED light, resistor, Android smartphone, and Bluetooth module. You will also need to use the Arduino IDE for this project. The circuit is minimalistic, no complicated connections involved here!

4. Wireless Weather Station Pro

As the name suggests, this is an Arduino-based wireless weather station that can measure the outdoor temperature and humidity via a sensor. Then, the data is sent wirelessly to the indoor receiver unit via transceiver modules. The system has a clock that tracks and shows the real-time even if Arduino has no power. The final output (temperature stats) is then displayed on an OLED screen. 

For this project, you require Arduino Nano, a DHT22 Sensor, an NRF24L01 Transceiver Module, and a DS3231 Real Time Clock. For the power supply in the indoor unit, you can use a 12DC power adapter, and for the outdoor unit, you can use Li-on batteries (7.5V).

5. Colour Sorter

Yes, this is an Arduino-based colour sorter system. Even though it sounds like a project for a first-grader, it is not! You need to have the basic knowledge of how Arduino works.

It is a pretty simple project. To make the colour sorter system, you will need a colour sensor (TCS3200) and two hobbyist servo motors. Other parts required for this project are Arduino Nano, breadboard and jump wires, switches, and a power jack. Also, if you want a cool design for the colour sorter, Solidworks 3D modelling software is a fantastic choice. 

So, this is how the project works – the coloured skittles will rest in the charger drop into the platform that is attached to the top servo motor. As the motor rotates, the skittles to the colour sensor that detects the colour of the skittle.

6. Compass

In this Arduino Project, you will design a digital compass using the Arduino IDE and a MEMS Magnetometer. The MEMS Magnetometer is essential for measuring the earth’s magnetic field. You will also need an Arduino Board and a few jumper wires. 

The interesting thing about this compass is that this isn’t a handheld one. Instead, it is a digital compass composed of multiple transparent images loaded into the Arduino IDE. You have to load the images in the working directory of the sketch. First, you define the image objects in the draw() section and then you use the image() function to load the background image. After this, you will see the compass image load. You can rotate the compass via the rotateZ() function. The compass arrow image is located at the top.

7. The MuttMentor

For this Arduino project, the idea is to create a smart dog collar that delivers an instant reward marker to reinforce correct behaviour on obeying a trainer’s commands. Essentially, the project is an automatic dog clicker that’ll give out marker tones when a dog follows the commands correctly. 

In the project, you will use TensorFlow to train a simple neural network to identify specific actions based on a small time window of accelerometer data while a dog performs a trick. You will need Arduino Nano, a buzzer, and a rechargeable Lithium-ion battery to build this project. So, if your dog is successful in performing the trick or command that you taught, the MuttMentor will emit a reinforcing marker tone.
