Summary of the Circuit

This circuit consists of an Arduino Nano microcontroller, a servo motor, a two-pin red LED, and a limit switch. The Arduino Nano serves as the central processing unit, controlling the servo motor and the LED based on the input from the limit switch. The servo motor is connected to the Arduino for both power and control signals, while the LED is powered by the Arduino and can be turned on or off by the microcontroller. The limit switch is used as an input device to trigger certain actions when activated.
