I am working on my guitar pedal and I need to figure out what size of a resistor I need to step down the 9 volt power supply in order to light up three LEDs that are run as follows:
All three anode leads are run in series to one another
All three cathode leads are run in series to one another as well.
Is that configuration correct? If so, what value of resistor do I need? The specs ons the LEDs are as follows:
First LED: Purple 20 m/A, 3-3.2V
Second LED: Pink, 20 m/A, 3-3.2V
Third LED: White, 20 m/A, 3-3.2V
Thank you!!!
