Sampling analog data

Sampling sata is particularly useful for analog sensors such as an LDR or a thermistor. Another good example is one of the MQ gas sensors that can be bought.

You can change the amount of samples to take and the interval which is in millioseconds

int sampleData(int analogPin, int samples = 10, int sampleInterval = 100) 
int sampleData[samples];
int val = 0;
for (int i = 0; i<samples; i++) 
sampleData[i] = analogRead(analogPin);
val = val + sampleData[i];
val = (val / samples);
return map(val, 550, 1023, 100, 0);
