I'm doing a little series of flashing LEDS, sort of like the knight rider examples you see everywhere.
Anyway, I'm trying to make sure I've got clean code - and from what I understand of C, this is valid. However also from what I understand, the Arduino uses it's own form of C, so certain things are bound to be a bit different.
Here's the code I'm having trouble with.
#include<vector>
#include<string>
int leds[] = { 12, 11, 10, 9, 8 };
int tempo = 300;
void setup() {
for (int i = 0; i <= leds.size(); i++ {
pinMode(leds[i], OUTPUT);
}
}
And the error...
17: error: vector: No such file or directory In function 'void setup()':
Bad error line: -3
In order for leds.size() to work, I need to include the vector and string libraries I've read. However, those aren't found when I compile the code. I'm not exactly sure where to go from here as C is relatively new to me.
That code is exactly what you would want if you were working in actual C (although you forgot to close you ")" in your for loop) however arduino C is different. It does not use the standard C libraries so take out the include statements.
The arduino uses a command called Sizeof to do this sort of thing:
I didn’t post the loop because I had that working fine. The code I had originally worked, I just wanted to make it as clean as I knew how to. I hate hardcoding things when simple loops will do them for me - makes it much easier to add things later on so there’s not so much copy/paste. Plus I get more room for other things that way.
