It sounds like you’re half way there. The program is loaded and working fine. So you problem is mostl likely in a connection or component. When plugging into usb power make sure you use a power only usb outlet. The arduino shares the tax/RC pins with other I/o pins. The reed switch is supposed to go to the 5v on the board. The video is a little confusing at that part and I need to correct it. Do you have 5v going to LED 2 and 3? The slide switch turns off led 2 and 3. So it might be a easy as that. But check for power and make sure that the digital in on each led is going the right direction. The arrows should point down the length of the strip. I’ve soldered a few of these LEDs and have never cooked one.
