Bluetooth & Voice Control DIY Science Robotic Car Project

DIY Bluetooth & Voice Control Science Fair Robotic Car Project Build your own Bluetooth and Voice Controlled Robotic Car Project – a fun and educational DIY Science Project for students and beginners. This smart robotic car can be controlled using your smartphone via Bluetooth or through simple voice commands. It helps students understand real-world concepts like robotics, motor control, sensors, and wireless communication. Perfect for school exhibitions, science fairs, and robotics learning enthusiasts in BD. Overview This DIY Science Robotic Car Project uses an Arduino Uno as the main controller with an L298N motor driver to manage four geared motors. It features an HC-06 Bluetooth module for wireless communication and a LM2596 buck converter to supply regulated voltage to the control circuit. The car is powered by a 3-cell 18650 battery pack and can easily be switched on or off using a rocker switch. Students can control the movement and speed using a mobile app or voice commands, making it an excellent educational and practical robotics experience.
