Arduino drive MOSFET

hy ,i have a project that i would like to finish.i worked an it for very long time.

its an led candle effect driven by arduino and MOSFET.

i have made a prototype of 3w led and it works.

but now i would like to make a 100w led strip for it to glow like candle.

is it even possible,and if it is what MOSFET fo i use and what tipe of Arduino is best for project,i used the smallest one for projects before.

any help wold be gratefuly appreciated

Put together a schematic of what you have built. Show all power sources.

For Low side switching, we'll use a logic level N channel MOSFET for the convenience. Logic Level MOSFETs operate within the range of 0-3.3 to 5 V range where we can easily operate using a microcontroller directly. See the operating Voltage (Vgs) is 3.84 V where it can be operated using even an Arduino.

Note the pull down resistor R3 is on the processor side of the Gate resistor R1. There are a lot of bad drawings showing the pull down resistor on the MOSFET gate, this forms a divider lowering the gate drive voltage.

How much current?

There are different kinds of LED strips... They are usually easier to use than individual "high power" LEDs (1W and up) because regular LEDs want a constant current source and strips are usually voltage-controlled (with current control/limiting built-in). But some are not dimmable. But you can make anything flicker, if that's what you want.
