Hey people
I'm making some small battery-powered circuits using AVRs and other kinds of logic, and I was wondering: How would you get 5V from standard batteries?
I've been thinking about 3xLR44 to achieve 4.5V, but I think that may just be a little low.
Also I thought about using a simple 7805 with some combination of batteries, like 3xCR3032, but I can't help thinking that there must be a better (and more clever) way.
The circuit in question consists of a single processor and three 7-segments, so the power consumption is limited. No more than ~200mA peak.
Feel free to educate me![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Thanks in advance.
