+ | ====== loop() ====== | ||
+ | After creating a setup() function, which initializes and sets the initial values, the loop() function does precisely what its name suggests, and loops consecutively, | ||
+ | |||
+ | ====Example==== | ||
+ | |||
+ | <code cpp> | ||
+ | int buttonPin = 3; | ||
+ | |||
+ | // setup initializes serial and the button pin | ||
+ | void setup() | ||
+ | { | ||
+ | beginSerial(9600); | ||
+ | pinMode(buttonPin, | ||
+ | } | ||
+ | |||
+ | // loop checks the button pin each time, | ||
+ | // and will send serial if it is pressed | ||
+ | |||
+ | void loop() | ||
+ | { | ||
+ | if (digitalRead(buttonPin) == HIGH) | ||
+ | serialWrite(' | ||
+ | else | ||
+ | serialWrite(' | ||
+ | |||
+ | delay(1000); | ||
+ | } | ||
