Greetings Everyone,
I have a little project  I'm undertaking (personal knowledge if you will). I haven't ventured into circuit boards, circuits, and electronics before, I'm actually more of a programming person, but with extra time and idle hands  so why not.
I've included a little diagram of what I'd like to accomplish. Where I'm getting confused is the conversion between multiple things. When I look at small 2" speaker. It is 500mW to max 1W. So to me this indicates for the speaker to produce sound it requires a minimum of 500 milliwatts and tolerates up to 1 watt (500 mW variance). Also an LED bulbs is rated at 2W for 250 lumens. Then also is strip LED lights, with a ratting of 14.4 watts per meter so divide by 3 (average) for 4.4 watts per foot. SO if I add it all up I'm looking for 1w + 2w + 8.8w + indicators + circuit board = 12w (loose estimate).
So then I go look at batteries. I see 2aH which is 2 amp hours (? please confirm ?). So then if a wire has a tolerance of 1.0v to 1.9v and its carrying current through the circuit board to the given attachments which require X amount of watts to work? how does amp hours in battery power translate across to watts to turn the bulb on? Further how does one determine how long before the battery is dead? Assuming that draw for all items is constant?
IF someone can point in the right direction so i can discover the pieces of the puzzle  really appreciate it  hints / tips and advice also very much appreciated.
Best Wishes. .
