Getting my ESP8266 working

I can not for the life of me get my ESP8266-01 working. I got it to do AT commands once and connected to my wifi. I would like it to get sensor data from my Arduino uno and send it to thingspeak. (Light levels and temp/humidity). I have searched hi and low and watched dozens of YouTube videos yet I can't find a good example to help me out. Does anyone have any good resources they are willing to share?

I looked at that library and couldn't figure it out. Need to look at it more. It's not fried I have very careful about voltage and always had it hooked to 3.3v I do have an external supply for it as well…

I'm starting to think that may be the best way to go. Can I use the same Arduino code?

Which ESP8266 do you have? When you talk about AT commands it looks as if your ESP8266 is a wifi module that is ment to be used by a differet MCU.

The ESP8266 is a compact wifi chip.

It is good if you can do AT commands, but you do not really have to do it. There are libraries available that hide all that stuff.

The easiest way to do what are trying to do is to use the Arduino IDE. Install ESP8266 libraries and off you go. Chances are you can simply adapt and add code to the WiFiClient example and connect to your home router to upload stuff on thingspeak.

On the gloomy side, if it was working and is not so now, well it is easy to fry! It is rated at 3.3 V and will easily get destroyed beyond 3.6 V. The inputs are not 5V tolerant. There are other 8266 based modules which provide 5V tolerant inputs for interfacing sensors etc.

OK, that is good. I used a nodemcu module to do the same thing a couple of years ago. It has all the I/O that you need so you do not need the UNO for this work. I had to use a little level shifter to accomodate 3.3 V and 5 V sensors.
