davisbaumung Posted July 13, 2007 Report Share Posted July 13, 2007 Hello i have etched glass and now i want to put leds in the background of the piocture frames. I need to know how to hook the leds circuit up to a normal plug in, so that they dont have to run of batteries. i have an ac ac adaptor it says direct plug in class 2 transformer model 28 - a09- 200, input ac 120v 60Hz 3 w , output ac 9V 200mA and it looks like this http://www.montek.com/cart/files/thumbs/t_27547.jpg so i think the out put would be 9v right so what kind of resitor would i need for by project it will have like almost 20 leds all hooked together so any help wopuld be great and could i just have one resitor then all the other leds hook in seriers (or paralle) Quote Link to post Share on other sites
Phil Posted July 13, 2007 Report Share Posted July 13, 2007 That depends solely on the amount of current and voltage the LED is supposed to take. Read what it says and report back.Phil Quote Link to post Share on other sites

isteve Posted July 14, 2007 Report Share Posted July 14, 2007 (edited) You can't plug them into a wall socket. You want DC power, and put led's in series. Different color led's also need different voltages.I would guess with 9v supply you could make sets of 3 in series and connect all sets to power in parallel. But I would check with someone that knows what there talking about first. I'm just guessing. Edited July 14, 2007 by isteve Quote Link to post Share on other sites
