Remote Control Car w/Arduino Uno, L298N Motor Driver, HC05 Bluetooth Module & Android Smartphone

The video tutorial demonstrates the setup and configuration of a remote-controlled car using an Arduino board. The instructor replaces a 9V disposable battery with a 7.4V rechargeable lithium battery and rewires the system to use a single battery. A Bluetooth module (HC05) is added for remote control via an Android phone. The instructor configures the remote control to move the car forward, backward, and stop, but notes that turning and speed control are not yet programmed. The video concludes with a recap of the components used, including the L298N motor driver and the importance of future adjustments.
