good tutorial! I received my esp8266 December 22, 2014. A few comments so far: I made several mistakes with the voltage divider. And it is my profession. Beware. fortunally i did not kill them. My advice order a logic level converter with it for only around 2 euros. Remember TX on RX and RX ON TX. I also noticed that the new esp8266 already sets on a baudrate of 9600. Finally, the AT commands only work with capital letters. And the serial monitor should be at LF and CR are otherwise the ESP8266 is not communicating. Anyway all credits for great scott!

Why is there any dislike he teaching us stuff be thankful and drop a like on his video

[@yekutielbenheshel354]

I agree with you. Intentionally down-voting this video is despicable. I suppose some people inadvertently down-voted it because they were tired, distracted, or drunk; others were probably bitter, others were probably nasty, and others were probably evil.

[@thomaskeystone6613]

There are dislike bots that go onto many youtube videos and instantly dislike every one.

[@ashishgautam7889]

sometime it is faster to find your video in dislike list rather than in liked video.

[@microk7648]

What is the point in making a dis-like bot?

[@Error-nf8yy]

I agree but just looking around the internet will show you that there are sad people with low self worth who negatively comment and rate just about anything. Plus stupid bots created by want to be hackers. You could see a video of a puppy saving a bus full of women and children and some people will hate on it. I think those type of people also seem to post and rate a lot more often than normally balanced individuals. A ratio of 6000 to 60 is actually a very liked video.

[@fuazexfuaze5484]

Extremely clear and handy! Though, nowadays it's far more easier to use the ESP without Arduino, there are multiple ESP based devboards and you can program them with the Arduino IDE.

"I hooked everything up as I described it before". You show the circuit for 1s. Do you have a circuit schematics?

No

[@nathangek]

You should do another video on the ESP8266. Espressif (company behind ESP8266) release their SDK and now you can program the microcontroller on the ESP itself using the Arduino IDE. No need for any microcontroller besides the ESP8266 module anymore :)

[@irishRocker1]

I was just going to ask why exactly he bothered with the arduino when you can program the 8266 but i didnt know the SDK wasnt always available.

[@ArgeKumadan]

that's because extra hardware takes extra space and costs. all i want is control a relay via internet. why would i need an arduino if i have a esp wifi card?

[@misaalanshori]

I love how a wifi module is now a full general purpose microcontroller lol

[@startobytes]

Hi, could you make a Video about how to use the Nrf24l01 with a button and a Led at the recever.

[@stevetobias4890]

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.

[@Jobobaboss]

this seems impossible. But i think about two moths ago, i had never remotely expected that i was able to do what i did now with the arduino. Making advanced menu screens, multitasking, using libraries and such. So don't give up. Giving up is not winning, and winning is not giving up. We and y'all can do this. It takes a little patience and frustrations, and maybe you get depressed sometimes, but that's ok. It's part of the process of learning, part of life. ;-) Arduino's are amazing! And thanks GreatScott! for your content!

[@8bits-pt]

There is an easier way to solder the female pin headers on the PCB, just slide the pins all the way to the longer side then stick them in the holes from the the top side of the PCB and solder them on the copper side.

[@halollisimo]

hey Scott, great vid! did u know you could just cut those onboard female connectors at 1:50 with side cutters instead of a hacksaw so you wouldn't get much plastic dust? same applies to cutting pcb - pair of tin cutters does the job w/o lots of residual dust. it isn't precise for fancy cuts but it is faster and cleaner that way imo

[@mbigras]

@GreatScott! Man I loved this video thank you so much :) just letting you know I think it would be really cool if you could do a demo video where you hook this up to a home appliance and power the home appliance on via a command sent over wifi, please please it would be so cool!!

[@greatscottlab]

I included the module in my 7 segment internet display project

[@mbigras]

right on thanks man, I'll check it out :)

[@KennethScharf]

The ftdi chip can be wired for 3v operation, no level conversion needed! Connect its 3v regulated output to the vio (io power input) pin. You may have to cut and jumper your FTDI board, adafruit ones can be rejumpered.

[@atm2042]

you should remove the plastic to solder the pins, afterwards you can place the plastic again

[@FakirCB]

+atm2042 That way he would never get the pins straight. I would personally rather use stripboard instead of a perfboard and an SMD version of the socket, which would make it a bit more comfortable, but either way is fine.

[@cankayabek949]

in situations like 2:00, i completely extend the pins in the black plastic, and insert pins through other side, to avoid touching the plastic with soldering iron

This is great, you should really have more subscribers for the quality tutorials that you offer. Keep up the good work. Could you make an extended tutorial for programming this with an Arduino.

[@fugit185]

Be aware that most (all whom I have asked) ESP8266 sellers in Aliexpress sell 30mm wide board which doesn't fit to 400 holes/tie points Breadboard, it is too wide. In amazon the still sell 26mm model. So be aware!

[@MrTalhakamran2006]

GreatScott! Please create a ESP8266 plugged with humidity sensor to check the humidity of soil and then turning water on/off based on humidity. Very practical and will definitely help a lot of folks out there.

[@freakqnc]

1:08 awesome! That's what I have been looking for! No more adding an arduino or (or RPi) to control a switch, pump, temp sensor, actuator etc. Simply get the ESP8266 IP and control its GPIO pins directly from a single page... Ideally one could connect to multiple modules at the same time to control a pool of ESP8266 modules at once rather than having to access them one by one by typing their respective IPs in the browser and load the control UI for just one module each time wanting to control a module. Can't wait for that to happen, then IoT will really take off! :)

[@SrgjanLDTeam]

this is awesome, i just ordered for just 2.95.. can you believe that :D i cant wait for it to arrive :D

[@briank3321]

Srg you probably ordered from ALI express, I bet your still waiting for it :))

[@SrgjanLDTeam]

@@briank3321 Nahh, I passed an exam with that one.

[@slincolne]

When soldering short runs of headers, sometimes it is better to put the pins in the long way, solder, and then push the plastic down. When I do this I place the finished adapter on a breadboard, and press the adapter down firmly to push the plastic up to the PCB. Saves mess and burnt fingers :-)

[@theKongston]

If you are having problems, swap tx and rx, your board might have the “wrong” or “right” markings

Thanks for the video. Concise and addresses the 3V signal voltage issue nicely.

[@crysis2killer]

HI, I would like to say that when connecting the ESP2866 in the arduino, check maybe it's supposed to be "Both NL & CR" in the Serial Monitor, I tried to use it with the Carriage return and it didn't work as you have shown in the video, so if anybody has a problem with that, try using the Both NL & CR option there...

[@darminaxel5809]

[@Sidabra24]

Nice video, Scot. Most FTDI serial breakout boards have 3.3V outputs. And, of course, most of them will have it labeled as 3.3V. I see yours is labeled simply as VCC, but I think it's actually 3.3V not 5V.

do something breaking out some of the other GPIO pins. I have a project that might not need them ... how about a temperature reporting unit, battery powered, that uses a Dallas Onewire thermometer? Optional, recharge circuit with solar cell. Another addon option, a data logging for 24 hours if no contact via WIFI. ... Whew... all just using this processor possibly with the -03 version instead.

[@majdinj]

I might be stupid, but why not to use 3 silicon diodes in series in order to step down 5v input to 3.2v? As we know the forward voltage of the regular silicon diode is about 0.6v, so putting 3 of them in series at the input side will reduce the input voltage by 1.8v 5v - 1.8v = 3.2v This will supply 3.2v with FULL input CURRENT limit. Sound legit, but is it possible?????
