I wanna make some sketch to generate number to represent sensor value, with range from high (900) to low (670), that number decrease with range between 1-10 and with some delay of switching number with range from 5-15 seconds:

void setup() {
  Serial.begin(9600);
}

void number(){
  int sensor=0;                 //variabel sensor
  int a=random(0, 10);          //range pengurang nilai sensor
  int delay=random(5000, 15000); //range delay perubahan nilai
  for(sensor=900; sensor>=670;sensor-=a){ //iterasi nilai sensor dg range 670-900
    Serial.println(sensor);delay(delay);}
}

void loop() {
number();
}

with output:

• 900 (delay 7 sec)
• 894 (delay 3 sec)
• 988 (delay 5 sec)
• 979 (delay 9 sec)

The sketch above was work as well, but i still can't using variable "sensor" result after iteration "for" in void loop. I hope you can help me, thanks.
