So I am attempting to determine if the battery I choose can power the devices I need. This is my first day doing anything with ohms and current and such. So go easy.
45mA Bluetooth card
3.9mA GPS card
2.0mA IR Thermometer
Now the arduino mini only says that it has a max output of 150mA so I don't know how much it consumes. For this example I am disregarding it because if I am right then I have a ton to spare.
So based on my thought process I think I get 2000mAh/51mA = 39.2 hours?
