Smile LM317 Driver but using a 200Ohm pot...

heres the schematic i built 5 minz ago

and i got all components at home but i didnt find a 100ohm pot so i used a 200 ohm pot instead... Is that ok? Will it work or can i "make" the potentiometer to 100 ohm by putting like a resistor somewhere i we heard.
The diode is a Red 16x DVD combo drive burner. and the voltage i will be using is 9v (not that it matters but anyway)
Thanks Anyway!!!
(cant test it yet cause i havent got my aixiz module yet :3)

Default Re: LM317 Driver but using a 200Ohm pot...

Okay after a few hours of searching other sites i found this on this forum... i got 50ohm potentiometers too so thats no problem... Will it work better with a 50ohm than a 200 ohm pot?

A potentiometer covers the resistance range from zero (dead short) up to the listed value, so a 200 ohm pot will work just fine. If you only use half of the adjustment range it is identical to a 100Ohm pot.
