Hey guys, I got the arduino uno with the project kit that came with a lot of components and a project book so I can learn the scripting for all this. I have almost finished the book so I have learned a lot. But I am still very much a beginner. I bought this because of a specific project I'm working on which will end with 7 servos and many LEDs (maybe 15 LEDs and 2 premade LED boards that I got here http://dx.com/p/2w-9-smd-led-126-lumen-6500k-white-dome-light-dc-12v-51001
). Here's my thought, I will only need 9 LED's to be controlled by the Arduino (on when a specific servo is one position and off when it is not). All the other LEDs can just stay on constantly; so can I just plug up power directly to the constant LEDs but have the same on/off switch for the arduino? I just don't want to have a bunch of on/off switches. As for the servos: there will only be 3 different actions.
Servo # 1: program 1
Servo # 2, 3, 4 ,5: program 2
Servo # 6, 7: program 3
Can I just put the same command wire connected to all the same servos with the same command to save outputs? For Example:
output pin 9 to Servo 1
output pin 10 to Servos 2, 3, 4, and 5
output pin 11 to servos 6 and 7
would that work?
Thanks for your help!
