Hi, yesterday my esp8266 failed me. After checking everything, I discovered that it failed in the “Adafruit_BMP085.h” library.
I replaced the library with “SFE_BMP180.h” and now it works correctly.
I have marked the lines of the BMP180, in case the error returned, for eliminate them easily.
I have also added V4 for see input voltage, just like on the screen.
I’m sorry I took so long to give a solution.
