This is my first LED project and I am new to the circuitry world in general. I wired up 28 LEDs into in a painting. Spec sheet is in images; I am using yellow, red, and orange. I am using a 5V 1.2A power source. I wired them all up in line and used a 150 Ohm resistor in between each one. I just tested the end points and it doesn't light up, which sucks because now I have to figure out how to fix this. I would love any ideas to troubleshoot.
I am pretty sure they are all connected from a neg to pos each time to make the current flow. I suppose it is possible I did not? However, how the heck would I know now that I have cut some of and can't tell which is which? I knew due to one being longer than the other? Any ideas on how to test it? I used solder to make everything stay together, and from what I understand that would carry the current as well.
The work doesn't look pretty haha, but I don't care as it is on the back.
