Traffic Light Controller is an Android application developed by LekPKD in the Education & Reference category. It serves as a sample controller for Arduino projects, specifically for controlling traffic lights. The application allows students to connect their Arduino board to their Android device via Bluetooth and control the traffic lights using predefined values.

This controller supports four phases of traffic lights: top, bottom, right, and left. Each phase is represented by a specific value: 1 for the top phase, 2 for the bottom phase, 3 for the right phase, and 4 for the left phase. The application also provides values for connected and disconnected states of the Bluetooth connection, which are 9 and 8 respectively.

With Traffic Light Controller, students can gain hands-on experience in programming Arduino boards and learn about traffic light control. The application offers a practical approach to understanding the concepts of traffic light sequencing and synchronization.

Please note that this application is solely intended for educational purposes and serves as a sample for Arduino projects. It does not provide a comprehensive solution for real-world traffic light control systems.
