I need to loop through different Pins in an Uno board, specifically over Pin # 3,5,6,9,10,11. (The PWM ones). I know how to loop over consecutive Pins:
for (int thisPin = 2; thisPin <= 11; thisPin++)
{
pinMode(thisPin, OUTPUT);
}
I do not know how to create a list of just the Pins I want and loop though it.
Arduino nowadays even knows the c++ foreach version of loops
int pins[] = {3,5,6,9,10,11};
void setup(){
for(int pin: pins){
pinMode(pin, OUTPUT);
}
}
Just as an addendum to @Roman 's correct answer.
Create an array of the pins you want to work with and loop through that like this:
int pin[] = {3,5,6,9,10,11};
void setup() {
//gets length of array
int len = sizeof(pin)/sizeof(pin[0]);
for(int i=0; i<len; i++){
pinMode(pin[i], OUTPUT);
}
}
You can choose to use len variable to make it easier to add or remove elements from the array as you're working with the code, or just set the size manually in the for loop
