 ===Commanding===
+The logic used to convert the tweets into commands is illustrated below. The existence or lack of each word in the tweet was checked in order to return a index-changing value.
 [[File:LEDcommand_flowchart.png]]
+As an example for the columns:
+<pre>
+int findDirHor (String check) {
+  if (check.indexOf("left") != std::string::npos && check.indexOf("right") != std::string::npos) {
+    Serial.println("left and right");
+    return 0;]
+  } if (check.indexOf("right") != std::string::npos) {
+    Serial.println("right");
+    return 1;
+  } else if (check.indexOf("left") != std::string::npos) {
+    Serial.println("left");
+    return -1;
+  }
+  Serial.println("nor left nor right");
+  return 0;
+}
+</pre>
