Disconnection Problems with Wemos Board

servoRAIN7.attach(7); // Set left servo to digital pin 10
servoWIND9.attach(9); // Set right servo to digital pin 9
servoSUN8.attach(8); // Set right servo to digital pin 8

The pin numbers that you’re using here are GPIO numbers, They aren’t the same as the D numbers printed next to the pins on your Wemos D1 Mini.

If you take a look at this:

ESP8266 GPIO pins info, restrictions and features

hi blynkers! the esp8266 mcu is widely used in iot projects. however, most gpio pins on this mcu have special / multiple functionality and are not safe to use in all circumstances. these “features” are still not well documented and not explained in a friendly manner for newbies. i see lots of cases when the “issues” are simply caused by not knowing which pins to use in which case. [esp8266 pin features] here is a basic table for startup. i’ve collected the info from various sources on the i…

You’ll see that it says that GPIO 6-11 are reserved, and shouldn’t be used (there are no pins connected to them anyway).

Edited to add…
I’ve just re-read this and I’m now not clear what type of board you’re using. You tagged your post onto a thread about a NodeMCU board, and you’ve said that you’re using a Wemos D1. If that’s a D1 Mini then what IO’ve said above is correct.
If it’s one of those Arduino sized boards known as a D1 R1 then none of my comments are relevant.

Either way, I’ve split this to its own topic, as I’m not sure that the two issues are related.
