5V for the atmega

The atmega microcontroller needs 5V to operate. The power source of the remote is a lipo-accu which outputs a charge dependend voltage between 3,7V an 4,2V.

The stepUp circuit needs to be designed

The power-consumption of the stepup converter needs to be measured to get to know if its necessary to disable the stepup converter in adition to save some power.

Done grafik

Debugging needs to be done, need some more information about power consumption of just the stepUp converter

Maybe some kind of mosfet needs to be placed between the battery and the step up converter to disable it (possibility to reset the processor with a software switch)

killSwitch added
