I am doing a project which involves around 20 Piranha LEDS. I am really stuck as I can't work out how they will go in the circuit, I know this may sound simple but it is really bugging me! There will be an 8pin picaxe chip going to a ULN2803( which I believe is a small integrated circuit with 8 transistors) which is then going to power the LEDS. I have worked out that the piranha LED has 3 colours and the resistors are red - closest to 72ohm, green/blue - closest to 80 ohm. Any help would be appreciated. Thanks.
