Generate pseudo Gaussian random numbers for pwm pins

True, but using summation, it is trivial to generate a reasonable approximation to a Gaussian distribution from the uniform distribution.

void setup() {
  // put your setup code here, to run once:
Serial.begin(115200);
}

void loop() {
int rg=0;
  // generate pseudo-Gaussian distribution with mean 0.0 and spread of +/- 1.0
for (int i=0; i<10; i++) rg+=random(1001);
Serial.println((rg-5000)/5000.0);
}

FYI this comes from the : Central limit theorem - Wikipedia
