So! I got a relay from Radioshack which requires a 9v 500ma to function. I'm using a 9v battery but it only lasts around 24 hours and I need it to last 5x that long on a battery. So I'm guessing I need a bigger battery but how would I not overload the relay? It goes without saying I don't know much about electronics
Is there a genius here that could help me with this? a shopping list would be awesome
