Hi All, I hope I can get some help from someone here as I am a novice with electronic circuits. THe project i am working on requires a micro water pump that uses 1.5v/150mA to power. I need to run this on a battery pack and it needs to run for about 14 days. Since there are no battery packs that will run the pump for that long, I was thinking of putting it on a timer to cycle the pump on and off.
I have a few questions (they may seem kinda dumb, but I dont know much about circuits.
1) The pump runs at 1.5v / 150mA. Most battery packs are not at that voltage. WHat should I do to get the right voltage.
2) Is there any standard circuits that I can build or make that will cycle on and off (1 hour on / 4 hours off)?
3) Would a timer ciircuit use up alot of the battery capacity?
THanks for the Help
