I bought a pack of 40 Gikfun 4 Color 5mm LEDs 5mm kit For Arduino from the link below.
I'm searching for the tutorials on how to make the LED change colors and keep running into a problem. The tutorials all have LEDs with 4 pins when mine (pictured in link above) only have 2.
I'm still very new to Arduino programming and wanted to find a tutorial to help guide me on how to use these. Thanks in advance for the help.
