I am attempting to control a 12V RGB LED strip (SMD 5050) from an Arduino Uno (and Nano), and have set up the following breadboard. When I power on the circuit with a 12v power adaptor, the led turns on to white, but doesn’t execute my sketch, which should fade from a color to another.
As I’m pretty new to this, have I made a blatant mistake? (Probably, as I seem to have fried my MacBook Air when I connected to both USB and power at the same time…)
Any feedback would be greatly appreciated
