While loop in Arduino
- The while loop() is a conditional loop that keeps running code inside parentheses until the provided condition is false.
- Until the tested condition is modified or forced to cease, the while loop will never escape.
- Sensor testing, calibration (calibrating the sensor input), variable increment, and other uses of a while loop in Arduino are popular.
Syntax:
while (condition)
{
// set of statements
}

Example 1:
int a=0;
void setup()
{
Serial.begin(9600);
while( a < 5)
{
Serial.println("Welcome to Arduino");
a = a + 1;
}
}
void loop()
{
}

while( a < 5)
{
Serial.println("Welcome to Arduino");
a = a + 1;
}
Serial.println("DONE");
Serial.println("Welcome to the code outside the loop");
