Below is simple program for user to enter and show float value in serial monitor
sometimes it wait for user to enter the value and sometimes it skips the loop and shows 0.00 in serial monitor.
/data from the monitor/
float change;
void setup() {
Serial.begin(9600);
}
void loop() {
Serial.println("enter float value to be displayed");
while (Serial.available()==0){
}
change=Serial.parseFloat();
Serial.println(change);
delay(1000);
}
Please help me to understand this
