Delving into arduino's for the first time having read an awful lot about various projects for a while - I've got some basic programming knowledge and some 15 year old gcse electronics knowledge, so bear with me if I'm overlooking basics or being a bit dim (no pun intended!)...
I'm making a sunrise alarm clock to help with the winter mornings - I have an UNO board, 12v led strip, 'borrowed' 12v 1A power supply from an old router and a guess at a circuit drawing (attached)
I've been having a bit of a read and it sounds like I might want a MOSFET rather than a transistor for the amount of current drawn - does this make sense?
Would there be any issues powering the UNO as laid out in the diagram? I.e. just run +ve and -ve to the board as well as off into the strip / switching component?
Sounds like 220ohm would be the value for the R switching the base if I was using a transistor ( the tip120 sounded like it was the weapon if choice, but I've just read a few other posts here with mosfets recommended...)
Any comments on my circuit or advice on components would be gladly received!
