so im a little noob i whant to build a machine that can make filament for my 3d printer and i am gone to use an heatcatrige 12 v 40watt
im gona use an RFP30N06LE mosfet is it possible to control the power true the mosfet from an arduino whith pwm signal??
Yes, but you will also need some kind of temperature sensor for feedback so your arduino code can adjust the PWM output value to maintain your desired temperature. This usually also involves using a PID function in your sketch to form a complete temperature controller.
i got the sensor the same as for the 3d printer just needed to know if i could control the mosfet whith pwm
just needed to know if i could control the mosfet whith pwm
Yes you can.

That MOSFET will dissipate about 0.5W so make sure it has a small heatsink. Better
MOSFETs are available that don't need heatsinking at that current level - choose one
with 0.02 ohm or less Rds(on) at Vgs=5V
150 ohm gate resistor and a 10k from the pin to ground are normally used.
