Summary of the Circuit

This circuit is designed to interface a joystick module with an Arduino 101 microcontroller to control a traffic light system. The joystick's position is read by the Arduino's analog inputs, and the microcontroller outputs signals to control the green, yellow, and red lights of the traffic light. The joystick also includes a switch that is connected to a digital input on the Arduino for additional input functionality. The circuit is powered through the Arduino, which provides a common ground and 5V supply to the joystick module.
