SOLVED: Any timer kills my sketch (ESP core version)

Create a new topic and use the category “Need help with my project”
Thoroughly read the text that pre-populates your post, and ensure that you provide ALL of the requested information and any additional information that may be relevant. This may include wiring diagrams or descriptions, serial monitor output (formatted the same was as code - see below), app screenshots, or background information about the purpose of the project.

Post your code, and once again follow the instructions in the pre-populated text about formatting. Unformatted code WILL be deleted.

Pete.
