Analysis

The main component that used for this project are light dependent resistor (LDR) sensor, relay and PIC16F877A microcontroller.

Conclusion:

As the conclusion, the objective of this project is achieved. All the component for this project was purchased. Then, I got and learn more information about the component for this project.

WEEK 1 : FYP 2 : RESEARCH ON PROJECT

Proceed to the next level from fyp semester 1, I do some research from the work flow to do some confirmation what type of circuit have to run my project. The circuit that will design depends on the flowchart of my project. So, after that i need to making the program code for the normal mode and flexible mode.

As the conclusion, it is very important to understand the circuit, classified the type and its function all of the circuit to make sure there is no problem occur in the future in the part of the combination the circuit and the programming development.

EXPECTED OUTCOME

Development of flexible traffic light using verilog HDL and implemented the verilog HDL using ALTERA DE2 for proof the concept in normal mode and flex mode.

• This project required students to develop a state machine based controller for traffic signals at a four-way intersection. The intersection has two travel lanes in each direction; north, south, east and west. In addition, each direction has a dedicated left turn lane. Each lane contains a sensor to indicate if a car waiting at a red light. Travel lanes also contain additional sensors to indicate if cars are approaching the intersection.

• This project design of a low cost performance traffic light system. This type of traffic light is suitable for town and small city where sophisticated traffic light system is too costly. Written in verilog on Quartus II software and implemented on DE2 FPGA Board.

AIM N OBJECTIVES

• To develop flexible traffic light controller
• To develop verilog HDL for flexible traffic light systems
• To implement the verilog HDL using ALTERA DE2 for proof the concept
