ATMEGA32 for Obstacle Detection and DC Motor Retardation 🚥🚘

Overview

This is a college course project that endeavors to leverage the computational capabilities of the ATMEGA32 chip to develop a sophisticated system, in conjunction with sensors, to ensure the utmost safety of passengers. Through the utilization of LED string lines, we aim to provide accurate indications of the proximity of objects to the vehicle from the LEFT, RIGHT, and FRONT directions. In the event of an absence of response, the ATMEGA32 chip assumes control and adeptly directs the car by implementing precise adjustments in its course and applying appropriate braking measures to guarantee optimal outcomes.

System Flowchart

Functionality of the Left & Right Proximity Sensors (GP2D120)

• At 8 units distance, 2 LEDs light up.
• At 6 units distance, 2 LEDs light up, and the car takes a 45-degree clockwise/anticlockwise turn if the driver does not respond.
• At 4 units distance, 4 LEDs light up, and the car takes a 90-degree clockwise/anticlockwise turn until the driver responds.

Functionality of the Front Proximity Sensor (GP2D120)

• At 10 units distance, 2 LEDs light up, and the car slowly brakes ensuring a pseudo-constant speed given that the driver does not respond.
• At 8 units distance, 4 LEDs light up, and the car slowly brakes ensuring a pseudo-constant speed given that the driver does not respond.
• At 6 units to 4 units distance, 4 LEDs light up, and the car brakes to a halt until the driver responds.
