Placing the average of serial readings over a period of time into a float...

in General Discussion • Other • 5 months ago

Is it possible to take, for instance, the serial readings over a period of 5 seconds and divide that by 5 to get the average... then stick that average number into a float?

Well, sure, it is totally possible.

It would look some thing like:

(Simulating reads avery second with a random number)

int time;
float[] reads = new float[5];
int last;
void setup(){
time = millis();
}
void draw(){
if (last == reads.length){
float total = 0.0;
for (int i = 0; i< reads.length; i++){
total = total + reads[i]; // adds all together
}
println("reads stored are : ");
println(reads);
print("that adds up to:");
println(total);
println("averaging : " + total/5f + "\n"); // average is done here
//reset position counter
last = 0;
}
// simulating input and adding to storage
if (millis() - time > 1000){
reads[last] = random(1);
time = millis();
// increment storage position
last++;
}
}
