This logic was translated into the following function (for columns): | |||
<pre> | <pre> | ||
//check is the retrieved tweet | |||
int findDirHor (String check) { | int findDirHor (String check) { | ||
if (check.indexOf("left") != std::string::npos && check.indexOf("right") != std::string::npos) { | if (check.indexOf("left") != std::string::npos && check.indexOf("right") != std::string::npos) { | ||
Serial.println("left and right"); | Serial.println("left and right"); | ||
return 0; | return 0; | ||
} if (check.indexOf("right") != std::string::npos) { | } if (check.indexOf("right") != std::string::npos) { | ||
Serial.println("right"); | Serial.println("right"); | ||

} | } | ||
</pre> | </pre> | ||
However, since the LEDs are declared in a 3x3 array, the indexes mustn't ever exceed 2 or go below 0. Therefore, the function for applying the index change was written taking these cases into consideration. | |||
<pre> | |||
//val is returned from the findDirHor() function | |||
void columnIndex (int val) { | |||
if (j == 0 && val == -1) { j = 2; | |||
} else if (j == 2 && val == 1) { j = 0; | |||
} else { j = j + val; | |||
}}</pre> |
