output pin 9 to Servo 1output pin 10 to Servos 2, 3, 4, and 5output pin 11 to servos 6 and 7would that work?
okay so because of the amount of servos I will need to have the servos attached to a separate power supply. So then I will have 2 power supplies: one for arduino and the other for the servos?
Depending on the servo and the LEDs. The LEDs are rated at 12V so you can drive them up to 12V. I would recommend a constant current driver to match the LEDs.This driver probably needs up to 12V supplied to it at 167mA per LED light (I think I remember reading 12V 2W). This 12V power supply can also power the Arduino. Arduino has a 5V regulator so it will take the 12V and regulate it to 5V for the arduino. You can also use the 12V supply to power some 5V regulated supply to power all the servos. You need to sum up all these current requirements to see what current rating that 12V supply needs. Although Arduino has 5V regulated supply, it outputs no more than 500mA (I'm guestimating) so you can't power all servos with arduino 5V pin.
You would need to read the sticker on the servo first. It tells you everything about how to power it. Post what you see on the sticker. You will likely need a 5V regulator if your servos run on 5V.
