Esp8266 serial port arduino serial#
I did not have a Serial USB to TTL converter so I opted to just use an Arduino and Serial mirror the commands. You could also buy a Serial USB to TTL converter and use a command based serial program like Putty to send these commands. This will also allow us to change some of it’s setting and get it connected to your Home WiFi.
Esp8266 serial port arduino software#
In this tutorial we will only demonstrate that it is functioning by Serial mirroring the Arduino IDE Serial port to a Software Serial port connected to the ESP8266. You can use the ESP8266 in a couple ways. It was perfect because it fits in a standard Breadboard, making one side rail 3.3V and the other side rail 5.0V.

I used the 3.3V supply in the Elegoo 37 Sensor kit. Use a 3.3V power supply with at least 500 mA of current. The 3.3V supply in the standard Arduino also doesn’t supply enough current to power the ESP8266 during its peak transients. DO NOT use the Arduino 5V as this will damage the ESP8266 permanently. Like the Photon, the ESP8266 is a 3.3V device so you must use 3.3V to power it. The ESP8266 will also teach you a lot more than the Photon as a lot of what the Photon is doing in the background with it’s integration with Particle, you get to learn how to do this yourself. You can make your ESP8266 a personal server or put it in AP mode to act as a WiFi access point. you have more freedom with how you use the ESP8266 to fit the needs of whatever your project is.

You aren’t trapped into using someone else’s cloud, or IDE, like Particle, and you don’t need the “support” enabled in order to use it. The ESP8266 is completely open unlike the Particle Photon. If you are on a tight budget or need to make a lot of something, learning the ESP8266 will be well worth your time. The price of the ESP8266 is just unbeatable on the magnitude of 1/4 the cost of some of the other solutions. With the ESP8266 being much more difficult to get started with, why even use the ESP8266? Well there are two really big benefits to the ESP8266 which depending on the project could outweigh almost any other IoT device like the Photon. For this tutorial I hope to bring this information to one place to get you up and running faster using an Arduino to setup and make sure the ESP8266 is working. The documentation is hard to find and a lot of Google searches return examples that either skip steps or are just wrong. However, as the Particle Photon was very simple to get setup and running with all of its support, the ESP8266 is leaps and bounds harder making the ESP8266 definitely not for beginners. The ESP8266, like the Photon, is a a WiFi enabled microcontroller module that can be used as a solution to any IoT project. This one of the many ESP8266 boards out there. After getting a lot of feedback from the community we got our hands on Riaspire ESP8266 WiFi board.

A couple weeks ago we looked at an Internet of Things solution, the Particle Photon.
