[QUOTE="HomeY, post: 1065164, member: 68365"] [ATTACH=full]145987[/ATTACH] Look at this image ;) My PSU has dual output. 1, 2 & 3 is Input from 230V, where 1 = Live wire, 2 = Neutral, 3 = GND 4/5 = -V, 6/7 = +V The Black wire from PIN 4 goes to the GND from Arduino (tried PIN 3, doesn't matter) The White wire from the LED strip (GND) goes to pin 5 on the PSU The Red wire from the LED strip (+5V) goes to pin 7 on the PSU When i connect the white wire from the LED strip to PIN3, i don't get voltage on the LED strip. GND / -V should be the same. [/QUOTE]
