Cheap WiFi modules

FYI for those of us that remember teletype which required a CR & LF in any order, these devices do not work that way.
You MUST send CR LF (10,13) in the correct order to work consistently. 13,10 will *sometimes* work, but not always.

Nothing worse than discovering a critical typo after the time to edit has expired. I've corrected it in the quote. Bottom line, use 10,13 in that order.

I think this site might be interesting for the IoT:

After registration you get a free channel for your data to be stored, graphed or used as you want.

True. People have done amazing things with the ESP8266, and uploading to Thingspeak. Also absolves you from having to learn HTML, I guess.

For those yet to discover these, there have been a slew of development utilities for the ESP8266.

And, folks have ported LUA (remember CHDK for Canon point-and-shoots?!), a scripting language to the ESP. The benefit being to be able to use the microcontroller on the module directly to store and execute simple programs. And with its own IO, one wouldnt even need a pic for simple applications.

My favourites are ESPLORER (multi-purpose, works with stock firmware and LUA) and LuaLoader (only for LUA).

These are available from Amazon (some via Prime with free shipping) for about $8. Now, to see if I can talk some dialect of Basic to them.

I bought 5 of these modules for $13.45 plus $2.25 shipping on ebay. I can't wait to start playing with these modules.

Greetings, Dave!

There is indeed a basic-of-sorts, a scripting language called LUA thats already been ported to the ESP8266.

Makes things much easier, and other folks have developed IDEs to be able to upload/load LUA files directly on the module.

In fact LUA is getting so popular, they have a separate sub-form for LUA at www.esp8266.com

If this generates more interest, I'll post all the LUA related URLs in my record.
