How Do I Make This More Concise?

earthvirgo10 · June 2, 2021, 7:17pm

I am a massive noob and I did an LED lightshow for a school project. I was wondering if there was a way to make it more concise because the endless high, low, high, low gets boring after a while. I did not make the randomizer at the bottom, I collaborated with my teacher on that.

// Starter Code
// 
void setup()
{
  pinMode(2, OUTPUT); //LED 1 is at pin 2
  pinMode(3, OUTPUT); //LED 2 is at pin 3
  pinMode(4, OUTPUT); //LED 1 is at pin 2
  pinMode(5, OUTPUT); //LED 2 is at pin 3
  pinMode(6, OUTPUT); //LED 1 is at pin 2
  pinMode(7, OUTPUT); //LED 2 is at pin 3
  pinMode(8, OUTPUT); //LED 1 is at pin 2
  pinMode(9, OUTPUT); //LED 2 is at pin 3
  pinMode(10, OUTPUT); //LED 1 is at pin 2
  pinMode(11, OUTPUT); //LED 2 is at pin 3
  
  
 
}


//How you want the lights to flash goes here
void loop()
{//start flash

Pack each pattern into a single "int".
Use bitRead if your bit-twiddling skills aren't up to scratch

  pinMode(2, OUTPUT); //LED 1 is at pin 2

Maybe get your teacher to explain why this sort of thing is a bad idea.
