Is it possible to pair the Nano and ESP-01 to remotely upload sketches via WIFI? I would like to install RGB strips or strings and their power/controller in a tough to reach place and am looking for ways to change the FastLed based sketches without climbing a ladder.
Don't.
Get a board with built-in wifi capabilty.
Thanks for your reply - I already have a handful of Nanos (non wifi of course) and have all but one slated for a variety of projects. I'd like to add wifi capability to it and take the time to learn how to integrate the two and do this, if it's feasible. If I fail, I can always purchase a wifi version in the Fall.
Have at it.
It's feasible. I have done it. I would not do it again, if I had another option.
Waste of my time.
I would rather spend my time learning about something that can be useful into the future instead of being stuck with something that is a kludge.
I appreciate your candor -
- why do you feel you wasted your time? Would you mind outlining what your project was and how successful you were?
I was successful. So what?
It is a waste of time, because I wouldn't use it on a project in the future.
one board instead of 2 boards = better option
Using an ESP8266-01 as a WiFi shield is a kludge which rarely works reliably.

If you need WiFi, just use a board with WiFi. My go-to board is the Wemos D1 Mini. If I need more I/O, the NodeMCU. There are Arduino boards with WiFi, but I have zero experience with them.
OK, you guys win. I can always use the spare Nano as a .... spare. I checked the node mcu esp2866 sold on Amazon and see it comes with breadboard pins and a stylish keychain.
With that said - I'll start browsing through the project hub and searching for something close to what I'd like to do. Do you smart folks have recommendations for tutorials or advice to offer as I start down that path?
Thanks!
Google is your friend. What is OTA Update - Programming NodeMCU ESP8266 Over-the-Air (OTA) using Arduino IDE

As I understand it, the NodeMCU does not in practice, have more I/O than the WeMOS D1 Mini.
It brings out some pins which are actually the interface for the Flash ROM which stores the program, so are not actually usable. Someone care to correct me on this?
If you want more I/O, you use I2C port expanders.
