You could do it "The Arduino Way". :slight_smile:

#include <MemoryFree.h>
void setup() {
  Serial.begin(9600);
}
void loop() {
  for (int n = 0; n <=100; n++) {
    int u = 20*n;
    int v = 30*n;
    Serial.print(n, DEC);
    Serial.print(", ");
    Serial.print(u, DEC);
    Serial.print(", ");
    Serial.print(v, DEC);
    Serial.print(", ");
    Serial.println(freeMemory(), DEC);

    delay(500);
  }
  Serial.println("Done");  
}
