5V LI-ion battery level ind...View Instructable »
i was reading this, imagining you talking in irish accent
nevermind my previous comment. i m so nab i totally missed to consider kirchoff's laws.... i am designing the pcb now . message me anyone for a copy if you want it.
is there any way i can regulate the margins of voltage that the leds are working? meaning, when i put it on a simulator, it works for voltages 3.7V to 4V. is there any formula to calculate the R1 and R2 or any other resistors needed for a lower margin 2V to 4.8V?
