Step by step process on how to use ESP8266 12e with Arduino UNO

Projects General Guidance

I have a project which is a line follower robot and then we are to add a special function to it so I decided to incorporate an ESP12e with it and control it wirelessly with an android app.

I have been trying to do some AT commands with it but it doesn't respond. Can anyone tell me how to properly do it? I am also not familiar with flashing, if there's a need to do it can you also please tell me how. And how I can write the arduino code to control it through wifi.

I've been trying to look for ways on how to make this work but I still haven't gotten any luck.

Can anyone please help me?

IMHO, it's much easier to program the ESP using the Arduino Core, and then send the commands (e.g. move forward) to the Uno over Serial (or SPI).
AT commands are just really cumbersome and very inefficient.

Take a look at this guide I wrote to get started with the ESP, I explained how to hook it up and how to program it.

Make sure you use a level shifter between the UNO and the ESP, because the 5V signals from the UNO will damage/kill the ESP.

Man do I feel dumb. After reading the last post I had an epiphany... All this time I was just thinking it was just a signal. I read the last post once & thought. Well, ok, just use the 3v to the ESP. Then I read it again. SIGNAL, he said SIGNAL. Now I get it! Not just the power but the signal is 5v as well. Hence the shifter. Wow. Slap forehead and move on! :confused:

Thanks!

Thanks so much man. At least I now have a source which is very understandable for a beginner like me.
