V. ControlProgram

// The LED is connected to the 8th pins of the Arduino Development Board with int ledpin = 8; // only the first execution is performed, and only one void setup () {pinmode (ledpin, output) is executed ); // set the digital I/O port mode. output is output} // This method will be executed repeatedly void loop () {digitalwrite (ledpin, high ); // set the voltage value of the 13-pin. The height is about 5 V. That is, the LED lights up delay (3000); // sets the delay time to 3000 milliseconds, in milliseconds digitalwrite (ledpin, low); // 13-pin voltage value, low = 0 V, that is, the led goes out and delay (3000); // wait 3 seconds}
 

Vi. Related PrinciplesFunction body: setup (), loop () use functions: pinmode, digitalwrite, and delay. For more information, see the official documentation: Traditional Chinese Syntax documentation.

Lab2 uses the "press the button" control led to add a button switch more than the current experiment.
