How to select functions randomly in my program

[Jack_Meadows]

I have very basic programming experience (as you will see) and I want to be able to select from a list of functions in my program randomly or create a program that will randomly select one of four digital outputs and randomly change delays.

The project is a 4-Channel Christmas Light Controller using 4 digital outputs from an UNO board to trigger 4 Crydom Solid State Relays.

Here is the code:

void setup() {
  pinMode(9, OUTPUT);
  pinMode(10, OUTPUT);
  pinMode(11, OUTPUT);
  pinMode(12, OUTPUT);

  Chase();      //List of functions
  Alternate1();
  OneOfFour();
  AllOnOff();
  FlipFlop();
  ChaseSlow();
  TwoOfFour();
  ReverseChase();
  Jitter();
  Twinkle();
  AllOn();
  Chase2();
  TwoStep();
}
void loop() {
  for (int i = 0; i, i <= 255; i++) { // Run program 255 times
    AllOn();
    Chase2();
    TwoStep();
    Jitter();
    Jitter();
    ChaseSlow();
    ChaseSlow();
    AllOn();
    FlipFlop();
    Twinkle();
    Chase();
    Chase();
    AllOn();
    Jitter();
    ReverseChase();
    ReverseChase();
    AllOn();
    Chase2();
    TwoStep();
    Twinkle();
    Alternate1();
    Alternate1();
    AllOn();
    Chase();
    Chase();
    OneOfFour();
    Jitter();
    OneOfFour();
    Twinkle();
    Chase2();
    AllOnOff();
    AllOnOff();
    TwoStep();
    AllOn();
    FlipFlop();
    FlipFlop();
    FlipFlop();
    Jitter();
    Jitter();
    AllOn();
    ChaseSlow();
    ChaseSlow();
    TwoOfFour();
    TwoOfFour();
    Twinkle();
    ReverseChase();
    ReverseChase();
    ReverseChase();
    AllOn();
    FlipFlop();
    Chase();
    Chase();
    ReverseChase();
    Chase();
    ReverseChase();
    Jitter();
    Twinkle();
    AllOn();
    TwoStep();
  }
}
void AllOn() {

  //digitalWrite(9, LOW); // 0000
  digitalWrite(10, LOW);
  digitalWrite(11, LOW);
  //digitalWrite(12, LOW);
  delay(50);
  //digitalWrite(9, LOW); // 0110
  digitalWrite(10, HIGH);
  digitalWrite(11, HIGH);
  //digitalWrite(12, LOW);
  delay(50);
  //digitalWrite(9, LOW); // 0000
  digitalWrite(10, LOW);
  digitalWrite(11, LOW);
  //digitalWrite(12, LOW);
  delay(50);
  //digitalWrite(9, LOW); // 0110
  digitalWrite(10, HIGH);
  digitalWrite(11, HIGH);
  //digitalWrite(12, LOW);
  delay(50);
  digitalWrite(9, HIGH); // 1111
  digitalWrite(10, HIGH);
  digitalWrite(11, HIGH);
  digitalWrite(12, HIGH);
  delay(2000);
}

The functions select variable patterns of output and delays which creates changing visual patterns. My goal is to create a program that will randomly select from the list of functions (or eliminate functions altogether) and possibly even randomize the delays so that the visual patterns are constantly changing without repeating. Crazy.

So I need some ideas of how to accomplish this. I looked at RANDOM and RANDOMSEED and I believe creating an ARRAY may be part of the answer.

The controller works great as is and as time allows I'll post the project.

Thank you for your time.

[J-M-L]

create an array of pointers to your functions
pick a random number within the bounds of the array
call the function at that index

something like this

// Declare your functions
void Chase();
void Alternate1();
void OneOfFour();
void AllOnOff();
void FlipFlop();
void ChaseSlow();
void TwoOfFour();
void ReverseChase();
void Jitter();
void Twinkle();
void AllOn();
void Chase2();
void TwoStep();

typedef void (*FunctionPtr)();

FunctionPtr functions[] = {
    AllOn,
    AllOnOff,
    Alternate1,
    Chase,
    Chase2,
    ChaseSlow,
    FlipFlop,
    Jitter,
    OneOfFour,
    ReverseChase,
    Twinkle,
    TwoOfFour,
    TwoStep
};
size_t functionsCnt = sizeof functions / sizeof *functions;

// define the functions
void AllOn() {}
void AllOnOff() {}
void Alternate1() {}
void Chase() {}
void Chase2() {}
void ChaseSlow() {}
void FlipFlop() {}
void Jitter() {}
void OneOfFour() {}
void ReverseChase() {}
void Twinkle() {}
void TwoOfFour() {}
void TwoStep() {}



// your main code
void setup() {
    Serial.begin(115200);
}

void loop() {
    size_t randomIndex = random(0, functionsCnt);
    functions[randomIndex](); // <=== this is where you call the random function
}

typed here so mind mistakes

Have a nice day and enjoy coding in C++.

[Jack_Meadows]

Thank you for the fast response. I'll study your code and give it a go. This will be a great learning experience for me since I seem to learn best from real world examples.

Cheers,
Jack

[Jack_Meadows]

Wow! I can see from your response that once you get to be an experienced coder you can "see" the global picture quickly. Please send me the code of your brain! I'll take the time to study and look up all of the references in your code and give it a try.

Cheers,
Jack

[J-M-L]

@Jack_Meadows

you can "see" the global picture quickly.

But you will have just random stuff no longer the patterns you were seeing. So he picked this suggestion very literally

@Jack_Meadows

or eliminate functions altogether) and possibly even randomize the delays so that the visual patterns are constantly changing without repeating

[Jack_Meadows]

Got it. I'll try both methods soon. The UNO board is currently installed in the controller outdoors and I'll need to extract it. I should purchase another board to go along with my simple breadboard simulator.

Jack

[LarryD]

@Jack_Meadows

I should purchase another board to go along with my simple breadboard simulator.

I should purchase another board several boards to go along with my simple breadboard simulator.

[camsysca]

@Jack_Meadows

simple breadboard simulator.

Pretty much falls by the wayside, when you look at Wokwi. Not so simple still demands a breadboard, but blinky blinky, well, go Wokwi!

list of functions in my program randomly

void funcA() {
  Serial.print(" funcA ");
}
void funcB() {
  Serial.print(" funcB ");
}
void funcC() {
  Serial.print(" funcC ");
}
void funcD() {

// declare type of pointer to array of functions
void (*ptr_funcArray[4])() = {funcA, funcB, funcC, funcD};

void setup() {
  Serial.begin(9600);
  randomSeed(analogRead(A0)); // for a more random value
}

void loop() {
  for (int i = 0; i < 4; i++) {
    (*ptr_funcArray[random(4)])(); // call the function from the array
    delay(1000);
  }
  Serial.println();
}

[2112]

@Jack_Meadows

I should purchase another board

Consider a Nano and breakout board for final implementation

Amazon.com: HiLetgo 3pcs Nano V3.0 3.0 Controller Terminal Adapter Expansion...

[J-M-L]

That’s basically the code from my answer #2

An improvement would be to ensure the same animation does not get selected twice in a row for example - many ways to do that

[Jack_Meadows]

Thank you all for your replies. I printed out your code responses and put them in sketches so I can study them along with the Arduino Reference and learn how to follow the code. I'll order another board so I can set up a test without having to retrieve my existing board from the outdoor controller. I'm sure to have further questions in the near future.

One again, thanks to all of you for your time.

[xfpd]

@J-M-L

ensure the same animation does not get selected twice in a row

The original sketch is a series of animations, many times duplicate, often repeating. The nature of randomness includes repetition. Uniform distribution is artificial. Ask any electron. : )

[J-M-L]

Sure
It was a suggestion

[xfpd]

And a good suggestion... I enjoy random light shows.

[Jack_Meadows]

Thank you, more food for thought.

Jack

[Jack_Meadows]

Hello J-M-L,

Your sketch has been edited with the functions defined and everything compiled without errors. I printed out your sketch and made notes after looking up some of the language references and also ordered another UNO board so I can set up a test set without having to break into the light controller.

More soon....

[J-M-L]

well done !

(I try not to print any more, it kills trees )

[xfpd]

@J-M-L - Your random-function-calling-function works...

@Jack_Meadows - Your code... revised

Using @J-M-L code in post 2... used "helper" functions to reduce duplication and replaced digitalWrite(LEDx, y); with direct PORTB writes.
