1-how to calculate and what calculations are needed to know how long batteries will last before replacement batteries.
2-and i was also wonder how transistor stage values were calculated
This what for a bike light circuit based around pic16f684 with a high power led
and a tip122 power transistor (3aa batteries)
was wondering if there was a equation or formula or working it out. any help?
