Hi,
my Wixel will run on rechargeable batteries. For this reason I’d like to somehow watch the input voltage. When the input line will be too low, I will do some precautions. The adc library for wixel can measure the 3v3 port and this is, if I get this correctly the output port. How can I correctly wire, to measure the input power level. And what needs to be taken in account, if the circuit is independent of wixel(I suspect the condirion for adc to measure the voltage is that the measured circuit will need to have common ground with wixel)
The small add-on. The internal thermometer is measuring outside(enviromental) temperature or the value is somehow biased with the board thermo radiation? Can I use it to measure “room” temperature?
Thanks for answer
Martin
