dhenry:
maybe someone can tell me if im connecting anything wrong ???
You do not need an arduino to try this:
- power -> led's anode -> led's cathode -> drain;
- source -> ground;
now, connect gate to power, the leds should light up; then connect gate to ground, the leds should be completely off.
everything works fine if the arduino uno is not there
update;
now i have pluged the arduino GND into the source and thr led strip does what is suppose to do. dont quite inderstand why... thanks for all the help now into the fun part programming would come back if i have any questions
Thank you very much to CrossRoads and everyone else that helped
