Cheap and Easy WiFi (IoT) Tutorial Part 1

Cheap and Easy WiFi (IoT) Tutorial Part 1 - ESP8266 Setup/Intro

День тому

In this video I'll show you how to get started with the ESP8266; wiring it up, flashing FW, and establishing a TCP connection to a data server
so you can post/retrieve data to/from your microcontroller.
Don't forget about part 2 and 3!

Really want to take the time to say thanks for making this video. I only started playing with the ESP8266 (ESP-01) a few months ago and have had nothing but trouble with doing firmware flashes with the Espressif tool. This tutorial got me in touch with some new resources I wasn't aware of and hadn't been able to find on my own. I'm glad to report I've finally had my first successful exchange over serial with this guy via AT commands. Finally the hair-pulling can end and I can get to work on some projects I've had in mind. Cheers and thanks again!

patiently waiting for the rest of the series as I have been trying to get these little jewels working correctly for some time. Would love to see hardware/code that demonstrates a round trip request/response that is stable and repeatable. Thanks for all your videos! Good stuff.

Very interesting subject Kevin, very well presented. I keep in mind the little tips for my next videos focused mainly on the ATtiny 85 (and 84), I will start the ESP32 soon.

@oldbloke135 6 років тому

It's amazing to think that this video is less than three years old and now all that circuitry can be replaced with a Wemos D1 mini board smaller than an old SD card!

Kevin, Thanks for sharing this. When you said that NRF24L01 node mesh network could be replaced with ESP8266, did you accounted for superior power requirements of NRF over ESP? If I had all sensor nodes running from DC it would not be feasible solution. If you know the way to use ESP in low power mode please share. Thank you.

@barakweizman3353 6 років тому

@charithab2027 8 років тому

Hey Kevin ! That video was very helpful. I've just started working on esp 8266. I'll be using it as a wifi module for msp430f5529 to send and receive data. Also... may I say ... my god ... you sound like owen wilson :D

Great and clear instruction. I need help, I have 02 esp module which get stuck during play with some AT command now one of them is giving solid state blue led on all the time. I cam flush the firmware but after that AT command not working. 2nd module working fine but after 1st power off and on its not working sketch removed.

@samermansour2157 8 років тому

@jacquesvanderwesthuizen7287 8 років тому

Would you recommend this product for video transmission? You use UART for the AT commands and UART would be too slow for video transmission. How can one use the SPI interface to get frames from microcontroler to the module so that the module can transmit the video?

@gurpreetjaspal 8 років тому

Hi, Can i have 2 of them connected as clients that communicate using my router as AP. Just like all other wifi devices communicate currently at my home.

@hoboat33 8 років тому

Great video, small snag. Toward the end when I enter the "Get" statement the first comment back is "busy s..." then "Recv 110 bytes" then same status comments as yours but instead of getting the data I'm getting "10,CLOSED" the first time "20,CLOSED" the second time "30,CLOSED" the third time, etc. Where could I have fat fingered? Thanks.

@JesusTejerinaRivera 8 років тому

Hi, thanks for your videos. Please, could you make a video of how to transmit data (round trip) for I2C between an Arduino UNO and ESP8266-01 module (using your normal firmware AT)? Logically their respective outline and sketch. Thank you.

Hey kevin, you should check out the "spark photon" that's coming out this March. It looks like a really cheap way to connect projects to the IoT. Seems easier than what you were doing in this video maybe. Just thought I would share. :) can't wait for the rest of this series though!

@LuenWarneke 9 років тому

Hi. In this video (part 1), you show your 'demo interface' sending data to the Arduino. In part 2 you link to your brilliant, well written code, but in the code you only have get_youtube() and get_current_temp(). How would you post data to the board, like turning on a pin or sending configuration settings? Thank you.

Kevin, Thanks for sharing with the world!!! Silly question for anyone. It looks like the rx/tx on a Due is 3v3, therefore no signal conversion/buffering needed, correct?

yep! you should be good to go, might still want an external 3.3 supply for the ESP though

@TheMrFrontera 7 років тому

Do i still need a windows OS to flash the ESP8266? I noticed when flashing he was using Windows, then the rest of the time he was using OSX. If I can't do it with OSX, can i do it with linux on my raspberry pi?

Hi Keren, You seems like ESP expert and you can help me out. I am using esp8266 and arduino uno (chinese version) as serial converter but my esp isn't working even the led on esp isn't blinking. I have checked the esp_input voltage and found that to 2.8 volts. I am badly stuck, can you please suggest the way forward. Thanks.

@sailinstyle 6 років тому

So every time this thing power cycles it comes back non-functional until you give it those few commands? No way to make it remember these mode changes, and connect to a preset wifi ssid on power up? You'd have to have something connected to the module to script these commands out to it every power cycle? What am I missing here? These things should be completely autonomous once configured...

@manutube8080 9 років тому

Really like this new stuff. I just want to know two things, how do you power up your arduino and how much power does the whole project draws. thx

@billglass5160 3 роки тому

I can tell you that the ESP-01 module is a power hungry beast that can consume 150 mA at times. I'm presently monitoring a bunch of stuff & sending it to ThingSpeak with an Arduino Nano & ESP-01. My Nano can only provide 50 mA of 3.3V to the ESP-01. Overload until I added an AMS1117 3.3V regulator from my 5V external power.

Since this video is a couple of years old now, the latest AT firmware can be found at www.electrodragon.com/w/File:V2.0_AT_Firmware(ESP).zip And the flash tool that I got to work can be found at esp8266internetofthings.blogspot.in/2015/10/how-to-flash-at-commands-firmware-in.html Just remember that your GPIO pin needs to be pulled to GND during flashing and when the tool finishes, switch it back to VCC and press reset once before unplugging and continuing.

@PatnaikUC 9 років тому

The "SSID" and the "password" is compulsorily to be written in the program.Thus for every other wifi router one has to enter that SSID and password. It will be better that instead of the SSID and the password written in the program , a computer interface is made on a terminal where the SSID and the password for the WiFi router are entered and then only the ESP8266 is connected to the Arduino for the rest of the program to run for whatever output is required

@milindkhurd 9 років тому

Hello Kevin, can you please give more details how the 2N3904 works as a logic level shifter. Still a newbie. I ordered a few BSS138, I have few of 2N3904, cannot wait to connect my ESP8266-07. Can you also let me know why you connected the GPIO02 to 3.3v, any particular reason? I think to use the esp I need REST, CH_PD, GPIO0 to be high only. Please let me know. Thanks a lot for all the good videos you have been posting.

@johnvbanta 9 років тому

I am wondering the same question (how the 2N3904 level shifter works). Specifically not following why the emitter is hooked to the 5v arduino and collector to the RX pin on the ESP8266 - seems backwards to me. Also curious about why GPIO2 is getting 3.3v.

@Kevindarrah 9 років тому

john banta sounds like a good video idea. The same thing can be accomplished with an N-Channel MOSFET. This isn't something I can break down in a comment though... stay tuned

@mk6595 9 років тому

It's easy to break down: The base of the transistor keeps the collector-emitter junction always "on". But the Arduino TX pin either allows or doesn't allow current to flow. When the Arduino TX pin is high then no current flows through the transistor and the ESP8266 RX pin sees the 3.3V (high). When the Arduino TX pin is low then current flows through the transistor and the ESP8266 RX pin sees almost 0V (low).
