Sorting voltage data from pin A0 to 3 variables (ranked)

Question

I don't have any code for this yet but I would like some ideas on coding it. I have a directional antenna that is rotating at a slow speed and a ham radio connected to the antenna. I have an output port on the radio that will put a voltage out from 0 to 5 volts for signal strength. I also have the rotational degree data that is captured. The question I have is do I try to do a long if then else statement to capture the 3 highest voltages and directions as variables for later processing or is there a better way. An example would go a long way as well.

Answer 1

It needs a bit more work but I would suggest using arrays to store the signal and positions something like this.. From (G7WJD) EXPIRED!

#define signalPin A0
#define degreePin A1
int signalStrength;
// STORE DATA IN ARRAY
// 0 [strength, direction]
// 1 [strength, direction]
// 2 [strength, direction]
int signals[3][3]; 
int degree;
bool positionSavedFlag = false;
void setup() {

}

void loop() {
 signalStrength = analogRead(signalPin);
 degree = analogRead(degreePin);
 // comapare with previous data
 for (int x = 0; x < 3; x++) {
  // have we saved data for this position before?
  if (degree == signals[x][1]) {
    // yes
    positionSavedFlag = true;
    // is it stronger than previous signal at this position
    if (signalStrength > signals[x][0]) {
      // yes so save / update it
      signals[x][0] = signalStrength;
    }
  }
 }
 // now since position not already stored , store it

 }
