Hello, I hope I'm posting this into the right section, if not you can move it to wherever.
I want to know if when constructing a dark activated circuit like the one below:
Does the circuit always draws current from the batteries?
What can I do to prevent it from drawing current from the batteries during the day? if at all possible? or draw as less power as I can and how do I calculate how much power I'm drawing?
The picture isn't mine, I'm going to follow the diagram tho, but I came here for suggestions and to understand how to calculate the power consumption of the circuit during the day.
Thanks in advance, Sagi.
