At first you will need one 250k potentiometer.
This is an instructable that teaches you how to use a potentiometer to dim an led.
This is how the circuit works.
Connect the other end of led to ground in series with a resistance.
Resistance can be in range of 120 ohm to 4 7 k ohm.
This potentiometer will be used for varying the voltage for dc dimmer circuit.
Make the circuit and upload the sketch in your ardunio uno.
Control your leds or led strip by using your own led dimmer circuit diy with potentiometer.
When the potentiometer is turned all the way to the side where it has a resistance of near 0ω the led shines the brightest because the circuit has the least amount of resistance at this point so it produces the greatest amount of current which is fed into the led.
After watching this tutorial you can control or adjust your led b.
