Schematics

Step 1

At first, you'll need one 250k Potentiometer. This Potentiometer is going to be used for varying the voltage for dc dimmer Board.

Step 2

Place the potentiometer during a certain place. and tin the three Points of the Potentiometer for better soldering for LED Dimmer. it'll increase the soldering strength.

Step 3

Here we are using IRFZ44N MOSFET. The IRFZ44N is an N-Channel Enhancement type MOSFET to that can Deliver high Output for an easy led dimmer circuit. This Circuit also works with other N-Channel Mosfets also. that's just about it and you'll use the Circuit for LED Dimming.

Step 4

Place the IRFZ44N is an N-Channel Enhancement type MOSFET during a certain place. and tin the three Points of the IRFZ44N for better soldering. it'll increase the soldering strength for DC BULB Dimmer Circuit.

Step 5

Now connect the Potentiometer and therefore the IRFZ44N with one another like as shown within the picture. The MOSFET's Gate pin are going to be connected with the center pin of the Potentiometer. and connect the drain pin with the corner pin of the Potentiometer.

Step 6

Here we are employing a single color 12V LED strip for pwm LED strip dimmer.

Step 7

Connect the LED Strip +ve wire with the Source Pin of the IRFZ44N Mosfet. and therefore the -ve Pin are going to be connected with the Potentiometer first Pin.

Step 8

This Red and therefore the Gray wire is for +ve and -ve respectively. we've to offer a minimum of 12v for running this board. during this way the Dimmer Circuit works.

Step 9

Here i'm employing a 12V switched-mode power supply (SMPS) for giving the 12v power to the strip Dimmer Circuit.
