If the drum is working then there is nothing wrong with it... but you can also have an array stored with values then move that value to your output word
For an example, the trainers I sell have a Pot and Meter, I move the input from the pot to the output on the meter... so if someone moves the pot to 25% then the meter also moves to 25%, so if you are using this for learning try getting a analog input also, then try doing the same
