arduino powered by 3.7 volt battery? Answered
Can an Atmega328 chip +oscillator run off of 3.7 volts without a regulator to be used for 7 channel pulse width modulation with mosfets to drive the leds?
I'm desiring to power it with an 18650 battery. (which charges to 4.2 volts and drains to 2.75 volts)
if not, how could i do it?
