 how to make 12v fan dimmer easy at home

In this project we learn how to make how to make simple 12v fan dimmer easy at home. using this circuit you can control all type of 12v dc motors speed as your demand. 

how to make 12v dc fan dimmer

for making this project we need some components.

Components:

  • 1RFZ44N Mosfet 1
  • 10K Variable Resistor 1
  • Heat Sink 1
  • Old fan dimmer casing
  • Soldering Wire
  • Soldering Iron
Now follow simple steps and make same.
  • 10k variable resistor has 3 pin. connect 2nd pin of variable resistor with 1st pin of mosfet,
    circuit diagram of 12v dc fan dimmer

  • Now 2nd pin of mosfet connect with 3rd pin of variable resistor,
  • 3rd pin of mosfet use for positive output,
  • And 1st pin of variable resistor use for negative output,
  • 1st pin of variable resistor also use for negative input.
  • And 2nd pin of mosfet use for positive input.
  • irfz44n 1st pin is ground, 2nd drain, and 3rd is source

in this project we use only 2 components with very easy and simple circuit diagram. its hold maximum 12v 2amp. for long life work you need to use large heatsink.
