5$ Arduino WiFi Module!? ESP8266 mini Tutorial/Review

Buy your ESP8266 here (affiliate links):

In this small Tutorial/Review I will show what the ESP8266 is, what this module can do and how to handle it the correct way.

i am a student so sometimes its hard to afford these type modules. but your videos inspire me to cut down my pocket money and have a good time with electronics. thank you so much.

first video in the context of tech presentation for a long time that really contains what the headline promised - and not a selfish video
that just says "ohh world - look at me"... thank you dude.

Arduino Wi-Fi module ... $5

Having Arnold Schwarzenegger talk you through it? ...  Priceless.

[gnormhurst]

Excellent explanation, very practical, and not long-winded like some of these 25 minute videos. To the point. Thank you!

hi, thank you for the video
I have a brobleme
when i connect it but it doesn't respond to any AT commands.

How would I be able to program this chip and control it via an mobile app? Im looking to for example create my own unlock system to unlock a back yard door via my custom mobile app. Basically control functions for it via an android phone. Please guide me. Thank You.

"$5 for wifi module..." *subscribes* "I put all the links to awesome projects in the description below..." *Subscribing intensifies*

Hi, i have experienced the endless resets on power-up. Do you have any suggestion for me (my ftdi supports 3.3v). I also tried a voltage division but the input voltage drop to 0.7v when i plug the esp-01. Thank you

is it possible to make a tiny wifi-based tracker (e.g. for a bicycle) with this and arduino nano or pro mini? This would obviously only work in a city with a prevalent wifi hotspots.

i've seen a lot of projects where they use such module to send the video stream from a camera to a raspberry pi. Is it possible to do the opposite ? I would like to configure my pi zero as a headless and have the wifi module receiving the video stream from the pi to drive a tiny TFT LCD screen I could wear on my face.

Nice tutorial, thanks! I do have a question: *before* you flashed the new v.0.92, when the 8266 still had 0.90, would it still respond to all the AT commands? I ask because I just got an ESP-01, which I tested at 115200 baud, etc. My module responds to only four commands: restore, reset, and AT+GMR. (It replies v.1.3.0.0) Any other command returns "ERROR." Is that normal, or is there possibly something wrong with my ESP-01? THANKS AGAIN!

Hi Scott, How do you switch 3.3 Vdc TXRX comunication from the wifi module to 5 Vdc TxRx from the arduino ? I have this problem with gyro module :(

[MatthewSwartIreland]

Hi Scott 

When I set up mine I am getting a driver issue have you got any ideas?

[stevetobias]

Make a weather station with a UV index that does a forecast lookup for your current location and also acts as a clock that has access to your Google calendar to remind you of upcoming appointments etc.
This would be handy to be able to plug into your car with a lithium battery to power it in sleep mode when the car ignition is off and a built in lithium charging module can charge the battery when you are on the road.

Hey Scott can I ask what's the difference bet the smd esp8266 vs the one you are using? I notice the smd esp does not have pins on it, please help thanks

[next]

just started. I would like to know how to determine how many pin with it's type and no. available on board on any kind of esp wifi board programmatically. Is there any program for this ?

[zihadmahmud]

Hi Sir,

I was thinking to change text in arduino matrix with smartphone connected to this wifi thing. is it possible?

[fanuchman]

Your video is so well done and professional compared to all the other videos I have seen. Thank you, and keep it up!

[Townie_au]

I have a weather station. The display connects to the weather station through a wireless link. However the display need to be connected to a PC through usb. There it has a program that needs to be running to sync the data to weatherunderground.com etc. I'm using windows server at the moment. Could I use something like this to connect to my wifi and sync it directly to the website and use the power from the usb?

I use an adapter. I tried to follow until 3:34 where i use the serial monitor then power up the board. However, nothing happened on the serial monitor. It is expected to display *Ready* right? What seems to be the problem
