I also brought the Radio Shack LEDs on clearance this past spring and promptly forgot about them. Then I started searching for useful information realizing that Radio Shack no longer provides support for the flipping things. The good news is that you can find the original Radio Shack instructions and code here: GitHub - RadioShackCorp/2760339-Tricolor-LED-Strip: Support files and example sketch for RadioShack Tricolor LED Strip (SKU 2760339) . I downloaded and followed the instructions on how to physically connect the LED Strip to an Arduino Uno R3 I also uploaded the sketch provided and then connected the Arduino to a 12volt /1 amp Power supply as the instructions detailed after disconnecting the Uno from my computer. The LEDs worked as advertised. I didn't have to do any special wiring with transistors or MOSFETs or splitters. To be fair it took a looooong time to find the flipping code and the other solutions that most people have found do work ; I'm just stubborn about things that should work as advertised without having to jury rig so much to get it to work. Also be aware that the sketch is doing low level bit banging to the strip and it is also doing port manipulation on the Arduino so be very careful how you modify the code because you can end up bricking your Arduino. Enjoy and Good Luck
