I have put alot of time into this laser project and im now stuck and looking for help. i finally got everything to work on my breadboard with a LED, but my new pot i bought will NOT turn the LED off at all. i can dim it, but not turn it off. when i used a mystery pot i aquired off a toy helicopter it worked fine, but i dont know the specs of it. if someone could look at my setup and tell me if it will be ok for a red or even a blue ray i will GREATLY appreciate it! as i am a 'newbee'.
here is what i have
25 ohm rheostat pot
47k ohm resistors
LM317T
47uF capacitor
1N4001 silicone diode
i tried to follow DDL's tutorial and he recomends a 100 ohm pot i had a 10K pot but i dont think it works anymore and I wonder if my new 25 Ohm pot will work, common sense tells me there is no way 25 ohm will work when 100 ohm is recomended, but i hope you all know something i don't. Thank you for taking a look at my post, any help is much appreciated!!!!
