Esp 01 Wifi Module Arduino

Now we are going to see how to program esp 01 module using an arduino uno with few very simple steps.

Esp 01 wifi module arduino.

The internet of things iot has just been made a whole lot cheaper and easier. Now you can manipulate inputs and outputs via wi fi using the arduino uno and the esp 01 module in the esp8266 series. Esp8266 module is of low cost and comes pre programmed with an at command set firmware meaning you can simply hook this up to your arduino device and get about as much wifi ability as a wifi shield offers this module has a powerful on board processing and storage capability that allows it to be integrated with the sensors and other application through its gpios. The esp8266 wifi module is a complete wi fi network where you can easily connect as a serving wi fi adapter wireless internet access interface to any microcontroller based design on its simple connectivity through serial communication or uart interface.

It was created as arduino wifi module but it s more power than an arduino than now if you must do a little module to control a relay or some simple digital datalogger it s the best solution. The esp8266 is a really useful cheap wifi module for controlling devices over the internet. The esp8266 esp 01 is a wi fi module that allows microcontrollers access to a wi fi network. In a previous story we saw how to flash firmware on esp8266 esp 01 module.

You can find news or update about this board here. Programming esp8266 esp 01 with arduino gpl3 esp8266 is an impressive low cost wifi module suitable for adding wifi functionality project. Download and install blynk libraries to your arduino ide its very important before programming search on youtube you can find easily. Adding this module to your arduino uno will open you to more and exciting projects.

If you have any questions about this tutorial do not hesitate to post a comment shoot us an email or post it in our forum. It can work with a micro controller like the arduino or it can be programmed to work on its own. The esp 01 module needs a 3 3v supply. This module is a self contained soc system on a chip that doesn t necessarily need a microcontroller to manipulate inputs and outputs as you would normally do with an arduino for example because the esp 01 acts as a small computer.

We can get the 3 3v for example from arduino uno board or using ams1117 3v3 voltage regulator which steps down 5v into 3 3v or directly from 3 3v source.
