Hello All,
I am having a problem with using analogRead() and Wifi at the same time. I have measured that Vcc is changing from 3.25 (no wifi) to 3.29 (with wifi) while supplying Vin with 6V.
The fluctuation of seems to influence analogRead() by a lot. I tried setting analogReference(AR_EXTERNAL) and connecting it to Vcc but is has no influence.
Anyone seeing this before, any suggestions?
Thanks
Markus
