Simple Solar Circuit Component Question
I've built a simple circuit that uses a transistor to switch from charging 2AA batteries during the day to discharging the batteries to power 3 white LEDs at night. (2AA batteries at 2x 1.2v is obviously not enough voltage to illuminate the LEDs which require 3-3.3v)
In order to fully power the 3 LEDs, I plan to add a third AA. (as shown in diagram in link) How would I change the components, specifically R1 and R2, to handle this increased voltage and fully illuminate the lights. Also, are there any other pressing concerns that would effect the brightness that I should fix and how? This should work right? thanks for the help! http://electronics.stackexchange.com/questions/178570/automatic-solar-light-far-too-dim-help-with-increasing-brightness |
