Hi i have a project.i use sparkfun blynk board esp 8266. This project shows how many buttons are pressed!. i have a issue with stability.One day. It says right number about how many buttons are pressed.One day it says wrong number about how many buttons are pressed.Is soldering the solution to the problem? what are other solutions? Reducing the number of cables is also a solution?
what i use
SparkFun Blynk Board - ESP8266
Resistor 10k ohm
Li-Ion Battery 3.7 volt 1050mAh

What you have is a current divider, not voltage!
