First, yes I've unplugged the power source.
Second, I'm an electronics newbie so please be patient.
Finally, I'm working on a project and I think I may have a short. But I'm not understanding why.
The project: An LED strip with a dimmer.
The problem: My breadboard was burnt and slightly melted along the positive and ground lines closest to the power source. Here is what the breadboard looks like:
Here is a diagram I wrote up (hope I got that right; it's my first attempt).
- LED = Neopixel RGBW 60 pixels/meter 1m strip
- MC = Arduino Pro Mini 3.3V
- AC = 120 V AC wall outlet
- DC = AC to DC power converter 5V
- C = 1000μF capacitor
- R = 390 Ohm resistor

Any help would be much appreciated!
