Traffic-light application in C language (AVR-007)

Learn to use microcontrollers to create traffic-light applications. In this project, the AVR-007 microcontroller from Circuits-Home will be utilized. Before developing the program, it is essential to understand the hardware specifications.

The project focuses on developing a traffic-light control system using the AVR-007 microcontroller. The AVR-007 is a versatile microcontroller that offers multiple input and output pins, allowing for efficient control of various components such as LEDs, sensors, and switches. A fundamental understanding of the microcontroller's architecture, including its pin configuration, memory allocation, and peripheral interfaces, is crucial for successful implementation.

The traffic-light application will involve programming the microcontroller to manage the timing and sequencing of the traffic lights. The typical traffic light consists of three colored LEDs: red, yellow, and green. Each LED will be connected to a designated output pin on the AVR-007. The microcontroller will be programmed to turn on each LED for a specified duration, simulating real-world traffic light behavior.

To begin, the hardware setup will require the following components: the AVR-007 microcontroller, three LEDs (red, yellow, and green), current-limiting resistors for the LEDs, a breadboard for prototyping, and jumper wires for connections. The LEDs should be connected to the output pins of the microcontroller with the appropriate resistors to prevent excessive current flow.

The programming aspect will involve writing code in a suitable language, such as C or assembly, that instructs the microcontroller to control the LEDs based on defined timing intervals. The code will include initialization routines, where the pins connected to the LEDs are configured as outputs. A loop will be created to cycle through the states of the LEDs, ensuring that the red light is displayed for a longer duration, followed by the yellow and green lights.

Testing the circuit will involve verifying the correct operation of each LED according to the programmed timing. Adjustments may be made to the timing intervals based on practical observations to achieve the desired traffic control functionality.

Overall, this project serves as an excellent introduction to microcontroller programming and hardware interfacing, providing hands-on experience in creating a functional traffic-light control system.learn to use microcontrollers to create traffic-light applications.
