Hello! I am really quite new to this field and am completely out of my element. I am trying to run five digital RGB LED strands from a single arduino uno. And I am having problems - needless to say.
Before making a complete wire mess, I did run the strand test and it has always been successful. It still is, I have just make a bigger mess of the wires since then. Currently, I have three of the five RGB LEDs wired together as a single unit and the other two wired together to act as a single unit as well. I guess, from five
5 strands
/ \ divided
3 2 and
/ \ soldered
1 1 to make 2 units
...if that even makes a lick of sense. Anyways. That's what I did and how they currently are. I did it because I wanted 3 of them to act together and the other 2 to work together independent of the other three.
Which now brings me to my problem. I have wired this mess up and now I am not entirely sure if I did it right.
So I have three of the send in port ~11, three of the receive in port 13, two of the send in port ~9 and two of the receive in port 8. And because I don't know any better all five strands are common ground and all five strands are hooked up to the 5V port. (The whole unit is attached to a 9V battery, if that is relevant) Is this set up right at all?
I have been successful in getting the three unit to light up and the two unit when I switch ports but I can't get all five to run the test run. Also, I currently have the three strand unit lit and the two strand unit's first RGB LED is completely freaking out. It goes either red or if I touch it, the unit starts blinking madly.
If there is anyone who can help, I would be really happy! I need help with the programming. I am so new to this, its kind of sad. I am a musician by trade, so I am completely lost.
