How do you manage the power to those devices? resistors? regulators?
November 22, 2010
Ok, some of you may notice this is relate to the quadbot I am building now. Those LED strip just an example, not really going to put it on my bot to make it low-cheap toy looking. As a begennier I really do confuse about these electronic stuff.
Here are the questions:
- There are spots 1. 2. 3. in picture(postive red wire). What should I use to manage the power from 11.1v battery? I know there are lots of resisters or regulators like 7805, 7809 etc. Which I should use to insure I don't burn anything here?
- How if 11.1V or 5200mAh 30C battery is too heavy for robot and I decide to use 7.4v or 2000mAh battery? Is there a formula that I can calculate what batter I should use?
- You may notice I have a switch in positive wire. Should I seprate into 2 or 3 switchs for each device? Should I have switch on positive or negative or doesn't matter?
- Some folks here told me each servo I have in picture probably take 1amp per each. Does that means I need to keep servo shield has 12amp current? Is that means if I have 4 servos are moving at same time and the rest of 8amp are going to each active servo which cause 1.2amp current running into active servos? or it still only draw 1amp?
- Sorry if I don't describe clear enough in any where or bad English, I will try to make it clear as possible in the future post.
Yep! very beginner stuff but it really confused me how to make a proper power management. Thanks for anyone who could kindly point out these questions or links.
