Top 10 Arduino Projects for Beginners – Part 3 🚀

The final part of our beginner series! These projects combine sensors, motors, displays, and communication modules to give you hands-on experience with more interactive Arduino applications.

21. LCD Temperature Display

Use a temperature sensor like DHT11 or LM35 and display the readings on a 16x2 LCD. This project teaches beginners how to integrate sensors with display modules, format output, and create useful monitoring devices.

22. RGB LED Color Mixer

Control an RGB LED using potentiometers or sliders to create different colors. Beginners learn analog input mapping, PWM for multiple channels, and combining signals to produce visually appealing outputs.

23. Simple Servo Robot Arm

Build a basic robotic arm using servo motors controlled by potentiometers or buttons. This project teaches motor control, coordination of multiple actuators, and introduces beginners to robotics fundamentals.

24. IR Obstacle Avoiding Car

Make a small car detect and avoid obstacles using IR sensors. Beginners learn sensor integration, conditional logic, and motor control to create an autonomous system that reacts to its environment.

25. Sound Level Meter

Measure ambient sound using a microphone module and display the level with LEDs or Serial Monitor. Beginners learn analog input reading, threshold setting, and visual representation of sensor data.

26. Water Level Indicator

Detect water levels using sensors or float switches and indicate levels using LEDs or buzzers. Beginners learn about sensors, input handling, and creating practical monitoring systems for real-life applications.

27. Traffic Light with Pedestrian Crossing

Extend the basic traffic light project to include a pedestrian crossing button. Beginners learn input-output integration, timing sequences, and conditional logic for interactive systems.

28. Bluetooth-Controlled LED

Control LEDs using a smartphone via an HC-05 Bluetooth module. Beginners learn wireless communication, serial commands, and how to create interactive projects with mobile integration.

29. Temperature and Humidity Logger

Log environmental temperature and humidity using DHT11/DHT22 sensors and display or record data. Beginners learn how to combine multiple sensor readings and visualize environmental conditions effectively.

30. Mini Home Automation System

Control lights, fans, or small devices using buttons, relays, or Bluetooth. Beginners get a taste of real-world IoT applications, integrating multiple components for practical, automated systems.
