#63688
Hello,
I'm new to code programming, I could use some help. This is my first time posting to this forum. I Have a ESP-12E module that I'm having problems with. The Wire library seems to be the problem. I've posted my code and the error log. I would appreciate any help I could get. I have been working on this project for weeks, sometimes another set of eyes helps. Thanks in advance.
