Explanation of the components:
Bluetooth Device: This component represents a device capable of Bluetooth communication, such as a smartphone or a Bluetooth remote control. The user interacts with this device to send commands to the car wirelessly.
Bluetooth Communication: The Bluetooth module, usually an HC-05, enables wireless communication between the Arduino and the Bluetooth device. It receives the commands from the Bluetooth device and sends them to the Arduino for processing.
Arduino Board: The Arduino serves as the brain of the system. It receives the commands from the Bluetooth module and processes them to control the motors and react to sensor inputs, if any.
Motor Driver: The motor driver (e.g., L298N) is an essential component for controlling the motors. It takes the control signals from the Arduino and converts them into appropriate voltage levels and currents to drive the motors.
Motorized Wheels: These are the wheels of the car that are connected to the DC motors. The motorized wheels are responsible for the car’s movement.
Motor Control Signals: These signals are generated by the Arduino and control the speed and direction of the DC motors. By varying these signals, the Arduino can make the car move forward, backward, turn left, turn right, or stop.
Motor Drivers: The motor drivers receive the control signals from the Arduino and act as power amplifiers to drive the DC motors connected to the wheels. They provide the necessary current and voltage levels to make the motors rotate as per the commands from the Arduino.
Power Supply: This is the power source for the entire system. It supplies power to the Arduino, the motor driver, and the motors. Usually, a battery pack is used to power the car.
Working Principle
The Bluetooth controlled car receives commands from a Bluetooth-enabled device (smartphone, remote control, etc.), and these commands are processed by the Arduino. The Arduino then generates motor control signals, which are sent to the motor driver to drive the DC motors. The motorized wheels move the car accordingly. Additionally, if there are any sensor inputs, the Arduino can use this feedback to adapt the car’s movement, such as avoiding obstacles when detected by the sensors.
