I've got this schematic for a very small lighting setup for my basement. The goal is to have two fixtures that have red, green, and blue lights that can be controlled with knobs on a Separate controller, (one brightness knob for each color on each fixture) and also a set of white LEDs in each fixture that can be strobed at different speeds (one brightness knob and one speed knob). The plan is to use potentiometers for all the brightness and have the output of each go to 4 LEDs in parallel with a resistor for each one. For the strobe I was going to use a 555 astable circuit with a very small capacitor so it goes fast, then link the output to a transistor so to impose the on/off signal to the output of a brightness potentiometer.
Any help with why this wouldn't work, what pots to use, or how to hookup the transistor right would be great.
LEDs are rated to have a 200 ohm resistor at 9 volts, Thats all I know.
Here is a rough sketch of the schematic.
