Step 8Check and Test
Check
Look over your solder joints carefully. Fix any that look weak or disconnected. Some solder may have leaked onto the fuzz (you can pick it off if you want), just make sure you haven't created any unwanted connections.
Test
Plug the strip into a breadboard to test the LEDs. I used a spare Arduino with a simple Blink sketch. With the extra wire on the end, it's easy to plug these into GND and a PWM pin.
Fix
If you have an LED that isn't working, look over your connections. Check for bad solder joints. If everything looks fine you may need to replace the LED. It's not a big deal. Clip the leads and insert a fresh one. Re-solder all connections, check and test until all LEDs are working.
