Arduino Nano is a popular board used for numerous projects, including automation solutions. It can be programmed by C, Python and Arduino IDE. It is one of the first Arduino boards that students use for several applications.

It’s similar in functionality to Arduino Uno. It functions with the help of the microcontroller ATmega328. Before we dig into the projects you can build with Arduino Nano, let’s have a look at its specifications to get better clarity when you have a look at the projects.

Arduino Nano Specifications

Digital I/O Pins: 14
Analog Input Pins: 8
Operating Voltage: 5 V
Input Voltage:: 7-12 V
Input Voltage: 6-20 V
Flash Memory: 32 KB out of which 2 KB is used by bootloader
Clock Speed: 16 MHz

You can use 6V to 20V unregulated external power supply to power the board. Alternatively, you can also connect a 5V regulated power supply.

5 Arduino Nano Projects to Try Out

1. Safety Device with GPS Tracking and Alerts

This is one of the most exciting projects you can build using Arduino Nano. This project is useful for women as a safety device. We are using Arduino Nano interfaced with GSM and GPS modules to send alerts to contacts and police by women who are in danger.

Here are the things you need:

RF transmitter and receiver
GPS module
SIM modem
Battery
Button

You can choose a GPS module with an in-built antenna and a powerful satellite search capacity. You can then program the board to receive the GPS signal and send it to a few select numbers with a specific message. So when the person presses the button, it automatically sends out an alert message to those contacts.

2. Volume Control

You can create an audio volume control device with the help of Arduino Nano and a potentiometer. A potentiometer helps in changing the resistance depending on the input, which will now be used to control the volume.

To build this project, you need the following:

PT2258 IC
Push buttons
Resistors
Capacitors
Speaker
Audio source

We will use the push buttons to increase or decrease the volume and you can test it with the help of the connected speaker.

3. Irrigation System

This is one of the often-built projects with the Arduino Nano board. You can create an automated irrigation system to water the plants with the help of this project. You will be using a humidity sensor and temperature sensor to test the water control and temperature in the soil. You will set a threshold in the code to turn on the watering system if the humidity and temperature decrease below a certain limit.

For this project, you need:

Humidity sensor and temperature sensor
Transreciever module
An OLED display

With just a few components, you can complete the circuit with Arduino Nano. You can connect it with your watering unit of the house and check if it works in real-time.

4. Key Locator

This is a cool project you can use in everyday life. How many times have you misplaced your key and searched all-around your home at the last minute?

Well, with this simple project, you can find your key quickly! All you need are:

Ultrasonic distance sensor
Bluetooth module
Battery
Electric buzzer
Bluetooth app

You will create this small circuit and attach the board to your key. You will then pair this device with your smartphone app. So whenever you want to find your key, you can just open your phone and press the find button on the app. The circuit rings from its location and you can quickly find your key!

5. Simple Tripwire Burglar Alarm

Instead of paying huge bucks for the anti-theft system for your entire home, you can create this simple tripwire alarm circuit at just a fraction of the cost with Arduino Nano.

To build this circuit from scratch, you need these components:

Ultrasonic sensor
Buzzer

After connecting these two with the Arduino Nano, you can place this circuit at a strategic position in front of your home. When someone comes close to this circuit, the ultrasonic sensor detects the movement and then sounds the buzzer. You can use a buzzer of higher audio range for a shrill sound.

Do you want to build such interesting projects? So, decide on a project and get started now!
