Play with IKEA DIODER and Arduino
Hi everybody !
I have an Ikea DIODER that I want to drive with my arduino UNO.
I'm quite noob with electronics and i'm looking for some help ;)
When I opened one of the for lamp, I saw 4 spots marked R, G, B and M (or W?). If I test voltage between the M spot and another one, I can read "14V".
So, I'll have to use the original power supply of the dioder because arduino can only deliver 5V max, am I right ?
My main interrogation is, how will I use the 0 -> 5V (with analogWrite() on pmw port) to get 0 -> 14V to power lamps.
I thougth to use some NPN transistor but I'm not sure this will be a great idea...
If some of you guys have some tips for me, you will make my day !
PS : as french guy, I'm sorry in advance for my bad english... :s
