Arduino程序结构:lopQ Blink I Arduino 0021 ⊙@回图四 Blnk§ Blink Turns on an LED on for one second, then off for one second, repeatedly This example code is in the public domain void setup[ // initialize the digital pin as an output // Pin 13 has an LED connected on most Arduino boards: pinMode (13, OUTPUT); loop函数一直循环运行 void loops digitalWrite(13, HIGH); / set the LED on delay(1000) // wait for a second digitalWrite(13, LOW); / set the LED off delay(1000); // wait for a second5 Arduino程序结构：loop() loop()函数一直循环运行
