Hi,
I'm really new to electronics, soldering, etc. - started about 3 wks ago. I'm building an airport for my 2 sons ages (almost) 3 and (almost) 5. I want to have 4 LED's to illuminate gate signs, 2 hobby motors that control rotating radars, and another set of alternating/blinking LED's for the top of the control tower. Ideally, I'd like them to be on one circuit running off one rechargeable battery, like a LiPo used for R/C aircraft, so we don't have to keep buying batteries.
Please see the attached schematic, this is what I came up with:
1. 4 x 2.2V, 20mA LEDs connected in parallel
2. 2 x 3.0V, 30RPM hobby motors connected in parallel, I could not figure out the current draw from the motors, I tried with a multimeter but the numbers were fluctuating all over the place.
3. 1 x 555 blinky from MAKE magazine (http://blog.makezine.com/projects/555-timer-blinky/), which is running off 4.5V (3xAAA), but not sure of voltage drop of this subcircuit or the current draw,
--1, 2, & 3 above are in parallel with each other (please see schematic)
So my questions are:
Will this work with what I have there?
Is there too much resistance to prevent current from flowing to the 4LED's?
Do i need more or less voltage from my battery?
Could I use a LiPo battery for this, if so, how do I decide which one is best (they're described in mAh, which I don't really know what to do with?
I know I could probably find answers somewhere, but I dont have alot of time for proper research so thanks for tolerating my questions, and many thanks in advance for any advice/help!
