I'm using the voice recognition modulator v3 to learn voice command. I understand the process of controling a single variable (like turning on and off an LED) But I can't seem to understand the code to control multiple variables. This is the code they provided.
How can I modify this to turn an LED on and off separately. Meaning 6 inputs. Like me saying red LED on, Red LED Off, Grren LED On, Green LED OFF, All On, All Off.
