HOVERBOARD

Project Description:

Hoverboard project involves creating a remote control hoverboard using an Arduino and a Bluetooth module. The hoverboard will be controlled via a smartphone or other Bluetooth-enabled device, and it uses DC motors for propulsion. The project demonstrates the principles of remote control systems, motor control, and Arduino programming. This project is ideal for students and hobbyists interested in robotics and remote-controlled vehicles.

Components Required:

• Arduino Uno with cable x 1
• Motor Driver L298N x 1
• DC Motors x 2
• Bluetooth Module HC-05 x 1
• Jumper Wires – Male to Female x 14
  – Male to Male x 2
• Chassis for hoverboard x 1
• Wheels x 3
• Power supply 12v Li-ion battery 18650 x 1

Learning Outcomes

• Introduction to Robotics: Understand the basics of robotic movement and control using DC motors and Arduino.
• Hands-On Engineering: Gain experience in assembling a functional remote-controlled vehicle.
• STEM Integration: Explore the integration of multiple components (motors, controllers, communication modules) in a project-based learning environment.
• DIY Robotics: Encourage creativity and problem-solving by allowing students to create their small DIY robots, combining education and entertainment.

This project will result in a fun and interactive remote-controlled hoverboard, providing an excellent introduction to robotics, motor control, and Bluetooth communication.
