I’ve grouped these projects by category, to make them easier to find.
Arduino LED Projects
The epitome of Arduino is learning how to flash an LED. (Am I right?!) But beyond just sending a HIGH and LOW signal to a digital pin, you can add logic, additional outputs, and create some pretty cool sequences using Arduino and LEDs. I recommend checking out these projects first if you’re brand new to Arduino and want to practice your new skills.
Featured Arduino Project: Record and Play Back a Push Button Sequence
Another Arduino Project for Beginners uses push-buttons and LEDs to record and playback a sequence. The concept behind this project can be used for Arduino games, Escape Rooms, or just to show off intermediate skills using Arrays, Debouncing, and Digital I/O. Here’s a quick demo video of the result.

Components You’ll Need for Arduino LED Projects
In addition to the push-button sequence project, here are some additional projects using LEDs.
Arduino Projects using Sensors
To use sensors with Arduino, you need to become familiar with how to interface them with Arduino digital and analog inputs. Most sensors have anywhere from two to four pins. Typically, sensors have three pins including ground, power, and signal. You can wire the sensor directly to the Arduino or set up your project on a breadboard.
Featured Beginner Project: Arduino Weather Station
This project uses an Arduino nano, a BME280 sensor, and an OLED display, along with a breadboard and jumpers to create a weather station. The BME280 sensor captures temperature, humidity, and pressure measurements and sends them to the Arduino via I2C.

Here are some additional ideas for beginner Arduino projects using sensors.
Arduino Bluetooth & Communication Projects
The third set of Arduino projects for beginners has to do with Bluetooth and communication protocols (Serial and WiFi). As a beginner, it’s important to learn how to use the on-board features of the Arduino. However, once you understand how to use sensors, the next step is to learn how to communicate with other devices. In these projects, you’ll explore ways to interface the Arduino with Python, Bluetooth Low Energy (BLE), and If This Then That (IFTTT).
Featured Beginner Project: Control Arduino with Python
This project sets the Arduino as a Serial device. Rather than using the Serial monitor to send a bit of data, you’ll use a Python script to write 1’s and 0’s to the Arduino. The Arduino will then turn on and off an LED. You can use this methodology as a starting point for more sophisticated Python projects to control Arduino hardware.

Arduino Motor Projects
The last batch of projects interfaces the Arduino with both servo and DC motors. While you don’t need a motor controller to drive servos on the Arduino, you will need one for DC motors and stepper motors. I recommend the L298N or the L293D chips. If you plan on driving a bunch of servo motors, you may want to consider an I2C servo driver that has its clock. That way you don’t tie up the Arduino while you’re trying to process multiple signals.
Featured Arduino Project for Beginners: Face Tracking
In this project, learn to control a pan-tilt servo mechanism with your face. We’ll use OpenCV for facial recognition and Python to send position data to an Arduino. The Arduino is connected via Serial and maps the position data to control the pan-tilt servos. It’s a pretty fun project, that’s sure to impress a crowd. Give this project a try!

Here’s a list of additional Arduino projects using motors.
Once you have a firm grasp on the fundamentals with Arduino, the next step is to work on more advanced topics such as Robotics or the Internet of Things. If you’re looking to get into the world of robotics, consider enrolling in my Build Arduino Robots course.
