Strange ADC behavior

[haldemir55]

Hi Karawin
I have a such strange problem with ADC of the Esp8266:
I finished all project steps and i got audio. When i connect add-on switches after 30 or 40 seconds the voltage on adc input drop suddenly to ~0.4.and waveing between 0.1 to 0.4. And it accept this value to do what it must to do. Increase volume and chage the station. When i reset it do same things.
Have you any suggestion.
And can you change for me the order of the switches such as:
STOP - > START
START -> NEXT
VOL+ -> PREV
PREV -> STOP
VOL- -> VOL+
NXT -> VOL-
Thanx
