Ulm2003a datasheet pdf4/27/2023 ![]() ![]() ![]() Logic level transistors would be best due to the lower gate voltage something like the IRLZ44N but depending on whether the strips are common anode or common cathode you with have to use NPN/N-channel or PNP/P-channel transistors or Mosfets but you could use non logic level transistors by using 2 transistors like the BC337 from the mircocontroller to the Mosfet to enable you to turn them on fully and lower the heat dissipation by the transistors. if you need to have a scale of color and you need to change it fast the TLC59 series IC`s are a better choice than 595 shift registers from Texas instruments LED Driver ICs | Products for LED Drivers | Power Management | TI.com and you will get 8bit grey scale control of each colour which is 256 shades of each colour to mix with both through hole DIP and surface mount IC`s but what every you do I think you are going to need to use transistors. Hi sorry for being so late but here we go if you have not purchased anything yet then maybe look at something like NeoPixels : Adafruit Industries, Unique & fun DIY electronics and kits they are more expensive than normal led strips but much easier to control and if you look on ebay for addressable leds you will find cheaper alternatives but if you already have 12v strips you can lower the voltage by removing the resistors on the strips which will bring the voltage down to about 6v per color line but it is a lot of work. ![]()
