Project Title: Traffic Light Simulation using STM32F407

Project Overview:

This project demonstrates a traffic light simulation using the STM32F407 microcontroller and its onboard LEDs. The simulation controls the green, red, and orange LEDs to emulate different traffic light states and patterns, providing a practical exercise in GPIO configuration, SysTick timer usage, and interrupt handling in embedded systems. The project includes individual LED blinking, combinations of LEDs, multi-LED patterns, and sequential LED patterns, all with precise timing managed by the SysTick timer. This project aims to enhance understanding of embedded programming fundamentals and real-time system operations.

Project Goals:

1. Individual LED Blinking:

Green LED: Blink on and off every 1 second. Red LED: Blink on and off every 1 second. Orange LED: Blink on and off every 1 second.

2. Combinations of LEDs:

Green + Orange: Both LEDs turn on together for 1 second, then turn off together for 1 second. Green + Red: Both LEDs turn on together for 1 second, then turn off together for 1 second. Red + Orange: Both LEDs turn on together for 1 second, then turn off together for 1 second.

3. Multi-LED Pattern:

Green + Orange + Red: All three LEDs turn on together for 2 seconds, then turn off together for 2 seconds.

4. Sequential LED Pattern:

Green → Red → Orange: Turn on each LED sequentially with 2-second intervals, and turn them off in the same sequence.

Components:

-STM32F407VGT6 microcontroller -Onboard LEDs (Green, Red, Orange)

Project Structure:

GPIO Configuration:

-Initialize the GPIO pins for the onboard LEDs. -Configure the GPIO pins as output using the GPIO_Pin_Init function.

SysTick Timer:

-Initialize the SysTick timer to generate interrupts every 1 ms. -Implement a delay function using the SysTick timer. -Create an interrupt handler for SysTick to keep track of time.

Main Application:
