IV. METHODOLOGY

A.  Component Description

1. Microcontroller (ATmega328)

AVR microcontrollers (Advanced Virtual RISC) are electronic circuits that can be programmed to perform a variety of tasks automatically. An 8-bit microcontroller with 32 kilobytes of flash memory for code execution, internal and external interrupts, serial programmable USART, serial port interface, and 6-channel 10-bit A/D converter (8-channels in TQFP and QFN/MLF packages) was the preferred controller. It also has a configurable watchdog timer that can be reset when errors occur and is designed for use with the least amount of human interference, an inbuilt oscillator A, and an inbuilt serial interface.

2. Bluetooth Module

The HC-05 can work in either Command or Data mode. The HC-05's built-in push button can be used to switch between work modes. The HC-05 enters command mode when the push button is pressed. When in Command mode, the user can change system parameters (such as pin code, baud rate, and so on) by using the host controller itself or a PC running terminal software and a serial to TTL converter.

Any changes made to the system parameters will remain in effect even if the power is turned off. After a power cycle, the HC-05 will return to Data Mode. Only when in Data Mode does a transparent UART data transmission with a remote device occur.

3. L298N Motor Driver Module

The L298 motor driver module is a tough and dependable solution for controlling the service motors of the voice-controlled and obstacle-avoiding robot vehicle. It sends precise control signals to the motors, allowing the robot to move smoothly and efficiently. The advanced circuitry in the module protects the motors from over-current and over-temperature conditions, ensuring their longevity and durability. Its small size and simple interface make it a popular choice for robotics applications such as voice control and obstacle avoidance. The robot can operate with precision and accuracy, providing a seamless user experience, thanks to the L298 motor driver module at its core.
