30 -32 inch led 5050 light strips

i am going to try to use an arduino to control the colors and intensity of 30-32 inch 5050 rgb light strips

i want to have just three colors displayed white ,blue and red i would like to be able to fade these also from 0% off to 100% full intensity. what i have read so far says i need 3 mosfets on each strip to drive the individual channels of leds the 32 inch strips will be daisy chained together for each individual color and order i want them in on the display

these are the rgb light strips i have purchased http://www.ebay.com/itm/231310011144?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649

the white and blue strips of leds will total out to approx 72 watts each at 12v per string of almost 5 meters each times 4 strips the red led strips of leds will come out to approx 72 watts total on a single 5 meter total length this comes to a total of 15 mosfets if my thinking is correct.

now for the questions 1-will i be able to use just 3 pins on the arduino to control the whole array of lights or will more pins be required to do this . 2- will these mosfets be good enough to do the job? http://www.ebay.com/itm/321464190015


If all the strips are daisy-chained, all the same colour, just 3 outputs needed.

No, those mosfets are no good. Find some logic-level mosfets.


hi Paul

thanks for the reply on the ladyada site they suggest a STP16NF06 mosfet is that the one i would need or could you possibly recommend what i need

thanks for the advise James

AOI516 from digikey.com. Here's a board with 32 of them I offer to control LED strips and a youtube clip fading strips up & down http://youtu.be/hAVf1D1L-7c http://www.crossroadsfencing.com/BobuinoRev17/

Are you sure that's the exact model they gave you? I think it should have been STP16NF06*L*. The "L" tells you it has a logic level gate. Alternatively the one Crossroads gave you.
