Modify LED fade in/out circuit?
Here is the breadboard of it. This works, so if the schematic is different, use this instead.
I want to modify it so that is uses a 5v power source. What resistor should I change and how many ohms shuld the new one be?
I also want to add a potentiometer so I can change the fade in/out speed. What resitor should I put it in place of?
Thanks for the help.
