Serial terminal with esp8266

To start communication you need following :-

• serial terminal like realterm, termite, etc.
• USB to UART bridge module (like cp2102)
• esp8266 module

Now connect module with bridge as shown in image below. and plug in the USB in USB port in pc.

Now open device manager from control panel and note port number on which your bridge is connected. 

Now open serial terminal and select that com port and choose 9600 as baud rate( default baud of esp8266 ) & click open port. Now send AT to USB in return you will get OK in return. 

You have started communicating with esp8266 and from list of AT commands you can perform required task. Similar procedure can be adapted to communicate with other micro controllers intead you will not need bridge in doing so.

For any problem in setting up esp8266 please comment under. Hit like and share if you really enjoyed the post.

Getting started with Esp8266

Esp8266 is WiFi enabled microprocessor chip module , mainly used to add WiFi compatibility to your blog. There are two chips on module, first one is esp8266 (microprocessor datasheet ) and other is external serial rom ( this chip may vary with manufacturer ).There are many variants of esp8266 module available in market as shown below.

  Out of this variants esp8266-01 is most common in practice & advisable for beginners. There are 8 pins in module as shown in figure. The module works on 3.3V logic level. Every module is preloaded with AT firmware This firmware provides user to interface with module using UART serial protocols. Their are set of At commands( AT commands are nothing but commands like Linux commands) that allows you to interact with controller & perform tasks like connect to WiFi, send bytes to server, receive message from server, and other functions. list of AT commands can be found here. You can also upgrade AT firmware version or create your own firmware and load it with help of tools provided by expressif (manufacturer of esp8266) 

There are many ways to start working with module. Some of them are :-

1. Interfacing with serial terminal using USB to UART bridge & provide commands from terminal.
2. Using arduino ide to program esp8266 in arduino's library function.
3. Upload lua firmware and program esp8266 in lua script.

From the above ways using arduino ide is most popular way to work with esp. 

Welcome post

Hi guys! welcome to my first post about my electronics hacks. first i would like to acknowledge you with fact that electronics is nothing but subject of interest. It's not like , that you will get success every-time , instead you should have to try again to get success. More you fails , more you will learn about different facts.Here in this blog I will provide you some most interesting techniques on how to start programming any microcontroller and interface them with different modules, communication protocols and many more.
we will also discuss some modules (ie esp8266,hc-05,etc) and how they work. Also we will understand different attachments like sdcard,LCD,etc. Hope you will enjoy blog and appreciate my work.
