Setup() in Arduino:
As the name suggest this function is used to setup the input, output pins in the arduino word. In this function you can do the serial initialization also.Function prototype:
void setup() {//Initialize
}
Functions used inside setup():
Serial.begin(baudRate); // Initialize serial communication at given baudRatepinMode(pinNumber,INPUT); //Initialize pinNumber as a input
pinMode(pinNumber,OUTPUT); //Initialize pinNumber as a output
Loop() in arduino:
This function is a super loop in the arduino world. This loop has life as like as the supply to the controller has. This loop will be executed infinite times. It is similar to while(1) and for(;;) in c and c++.while(1){ void loop() {
//your functions == //your funcions == for(;;)
} }
