script setup语法识别

As an AI language model, I can understand and generate scripts in natural language, but I don't have the capability to recognize specific syntaxes of programming languages. However, I can provide you with a brief description of the Setup function in the Arduino IDE, which is used to initialize variables, pin modes, and libraries before the sketch starts running.

The basic syntax of the Setup function is:

void setup() {
// statements
}

The function header indicates that the function has no return value (void) and takes no arguments. The statements inside the curly braces are executed once when the sketch begins. Common statements used in the Setup function include:

- pinMode(pin, mode): sets the mode (input or output) of a digital pin.
- digitalWrite(pin, value): writes a digital value (HIGH or LOW) to a pin.
- analogReference(type): sets the reference voltage for analog input pins.
- Serial.begin(speed): initializes the serial communication with the specified baud rate.
- LibraryName.begin(): initializes a library.

The Setup function is called automatically by the Arduino IDE before the loop function.
