[@anekinoo7]

I could barely understand you with the music playing.

[@davidwest3664]

i had to watch with CC

[@captaindrywall]

yea why the music on the pretty much crappy audio anyway

[@samuelsantanam]

One question: Why you not use the NodeMCu for send IR ?

[@Snsee]

I second that question

[@DoraFurlong]

For those who try this project and Alexa/Dot does not recognize your devices, you may need to go into board manager and install the ESP8266 2.3 version rather than the newest version.

[@figyuanewb4726]

Thank you for this comment, it really helped me a lot.

[@crazytacowizerd6299]

Ik this might be your perfered way but you dont need to use the arduino you can use the nodemcu by its self just put the IR transmitter directly to one of the GPIO pins

[@nuwang1]

crazytacowizerd yeah was wondering why he didnt just do that??

[@crazytacowizerd6299]

nuwan goonewardena me too

[@Smartskaft2]

Is there a reason why you chose the ATtiny85? I accidentally ordered the 45 (4KB flash memory instead of 8KB), do you know how large the compressed file you flashed yours with was? Thanks for the video! It has a good flow and I think you explained it on a good level. Not too detailed but still bringing the vital information to the table. Nice work!

[@zahor0269]

Im sure it can based on how you used it, but just to ask, can this be used to change the inputs and adjust the volume up and down?

[@noahreynoldsriding3452]

this is pretty cool Greg. god to see that your doing good on this channel

[@Dontra761989]

Love your video drop more I like the pictures and the break down of module and fully how to set up with every step

[@nuwang1]

Nice work man... Currently trying to do something similar but with just the esp8266... What problems did u run into trying to do that? Plz elaborate if u can... Thank uuu

[@nuwang1]

I mean without the arduino.. And run the ir codes from the esp8266 itself

[@jocelynwotring4802]

Love to see the schematics or instruction on the bootloader shield and how you program the ATtiny in a future video. Thanks for another great video.

[@leglessinoz]

Could one use an Arduino Mini instead of a Uno or is there not enough program space?

[@ktarinisingh7614]

Could it be possible to do the same thing using ESP-01 ESP8266 Serial WIFI Wireless (which comes with Arduino UNO Kit)?

[@RiFT1986]

Your voice sounds wayyyy too low relative to the music my dude, but good video otherwise.

[@khaledfwzy32]

thanks Gernsom very great project...sorry i am old man with age 50 year but interested with electronics project..where can i find the Alexa and it is working with and kind of contorting project with arduino

[@Grensom]

Thank you! I listed all the materials needed for this project in the description.

[@HacksterIo]

Love it! Any chance you can do a write-up? You may also want to consider entering our Alexa and Arduino Smart Home Challenge as well!

[@Grensom]

Thanks, Just did: www.hackster.io/grensom/use-alexa-to-control-your-tv-916ca6

[@arnprasad]

Your github page says it no longer works and points to another part where IR transmitters not used..what gives?

[@maykelfarronay]

I keep getting an error "invalid library found in C:\....." you seem have gotten the same issue when uploading IR-Alexa to arduino, I can see it at 5:43 how did you fix that error?

[@Mevangeli]

When I plug the Wifi module into the pc, the blue light blinks once, it does not stay on like yours and therefore I am unable to upload the sketch. Any ideas?

[@pjuzer]

Where can i get complete Library for IR ? Please share the link

[@willbethard3946]

I'm getting an error 'class fauxmoESP' has no member named 'onMessage' when trying to upload this sketch, any ideas on what to do? thanks

[@andrewgaming4941]

same , and i don t now what to do...

[@moepes]

If its still important to you: change: fauxmo.onMessage(callback); to: fauxmo.setPort(80); // required for gen3 devices fauxmo.enable(true); fauxmo.onSetState(callback); and this: void callback(uint8_t device_id, const char * device_name, bool state) { Serial.printf("[MAIN] %s state: %s ", device_name, state ? "ON" : "OFF"); to: void callback(unsigned char device_id, const char * device_name, bool state, unsigned char value) { Serial.printf("[MAIN] Device #%d (%s) state: %s value: %d ", device_id, device_name, state ? "ON" : "OFF", value);

[@Ran1906]

Hi! Im new in all Arduino stuff, can you tell me, can I use Arduino Nano for this?

[@Satyajit_Dey]

Yes you can

[@vkanth2]

Other than turning the TV on or off can it do other functions such as changing channels or volume? WIthout that I don't see much practical use.

[@nuwang1]

Vijay Kanth well obviously... U can do whatever u want.. Im trying to make one that controls everything, rv ac cable

[@vkanth2]

nuwan goonewardena If you get that working I'd want to know!!

[@jacobstech1777]

Hi. Can we use Alexa pi instead of Alexa?

[@G2675-v7m]

Que programa usas para programar a alexa para que encienda el tv?

[@superucranian]

Do you need a smart hub to do his or does the arduino act as one?

[@Grensom]

You do not need a smart hub, the Wi-Fi Module acts as your multiple devices and the Arduino sends out the IR Signals

[@shanesomerville2334]

Any chance you could do a tutorial for this but with a raspberry-pi-zero and google home?

[@Grensom]

I was thinking about doing something with the Google Home soon, yes!

[@mike8th411]

Shane if u wanna use google home get a chromecast its only $35 or $60 if u want the 4k model . The chromecast will work amazingly and u can also do more things

[@Muscat17]

Hi, Great project, I was wondering y do u need to use a Arduino UNO, are you not able to combine the code all onto the ESP8266? I am current trying to get this project working, but keep getting this compiling error. Build options changed, rebuilding all In file included from C:\Users\andre\OneDrive\Documents\New folder (2)\ESP8266\ESP8266-Wemo-master\ESP8266-Alexa\ESP8266-Alexa.ino:3:0: C:\Users\andre\OneDrive\Documents\Arduino\libraries\xoseperez-fauxmoesp-50cbcf3087fd\src/fauxmoESP.h:106:9: error: 'WiFiEventHandler' does not name a type WiFiEventHandler _handler; ^ exit status 1 Error compiling for board NodeMCU 1.0 (ESP-12E Module).

[@abdullahzafar870]

Great Job man wish you will have a great and a successful life✌

[@Tony770jr]

Nice project. However, the background music is too loud. Also, the Node MCU should be able to run the IR LED without the AT Tiny..

[@Dpfpv1]

Can you do the same thing with windows 10 machine and not Alexa ?

[@csquared9660]

Why can't the IR LED be driven directly from the NodeMCU?

[@Grensom]

I tried that at first, but the protocol I used to make the NodeMCU into a "WEMO" device made it difficult to also send the signals I wanted using the IR Sensor. I am looking into this more to find a more efficient way of doing this as you mentioned. I definitely agree that would make this project better! Thanks

[@SvetiMFNikola]

It's possible to work also with KZbin?

[@tonyrollin402]

Hi what would you charge to build one for me ?

[@youssefmosalam4638]

This video is perfect But could i use esp8826 only?

[@ioanniskoutroulis5866]

Great job my friend... I have done the same thing but I have connected an arduino mega instead and the IR controls also my home A/C...The only problem it's the range of the 3 IR led ( I'm using 3 for better range ) but I have found a solution for this with a 3 Watt IR Led Sensor witch I have bought from ebay..

[@ClarkeAfterDark]

great video...but you have to work on dipping the music down when you are talking. Its really hard to hear you.

[@waylem]

good content. Any chance you can do it without the music?

[@Jarramirez1]

The code for the Arduino uno would be the same for the ATtiny85?

[@Jarramirez1]

Did you use the 100 ohms resistor when you used the ATtiny85?

[@Grensom]

Yes, the code is the same except you might need to reconfigure the pins you use. Other than that you have to upload ArduinoasISP sketch to Arduino, build sketch to connect Arduino to ATtiny, then can upload code to ATtiny from the Arduino - Also yes you need the 100 ohm resistor in series with the IR Transmitter always, on my perf board it was on the bottom so you couldn't see it

[@OWSKIB]

Is it able to turn on any Netflix show?

[@kissfann2247]

What am i a scientist.Dam

[@gianmora1866]

Is this possible with Google home?

[@varionpereira8889]

When is the video for Google home coming ??

[@TechAirHub]

Can I control this using my phone's Google assistant

[@adrianpicos4447]

Could you do google home version please

[@kabak6623]

Mate music is too loud! I loosing content because of it.

[@LiliBcreation]

Cut the music behind you .. can't hear you properly :(

[@adrianpizzaro9709]

can i used Raspberry pi?

[@grandmav]

Too complicated. I want to tell Alexa to connect to my tv and done.

[@ezekieladams3944]

did not understand but it was cool

[@karissa4327]

So your basically telling me I have to tear apart my house to get some little tiny thing to connect my dot to my tv and lights. 🤦🏻‍♀️😂

[@matthewfavreau6893]

For some reason I am unable to get hex codes

[@biljacob]

where 2 buy plz

[@ARTTM143]

Bill Jacobson can I buy him?

[@gustavoovando3360]

Amozan

[@dpinvidic]

As stated, music is too loud..and distracting....you project is cool enough

[@kngpin48]

The music is way too loud...too many steps...just offer us something we can buy

[@keshavtiwari1632]

Why don't you teach IOT in MIT or work at google? 😐

[@ahmedsaker3781]

can you make it work with siri

[@nuwang1]

alexa wont detect the device greg... what do i do :( :(

[@Grensom]

When you uploaded the program to the ESP, did you make sure you changed the credentials to the same wifi you Alexa was on? Also did it say Upload was completed successfully?

[@nuwangoonewardena1205]

sorry this is my other account.. yes it showed the success message, connected to my wifi

[@nuwangoonewardena1205]

Is there a skill that i have to add to alexa before it detects the device? I have already added my yeelights, do u think thats causing some interference?

[@nuwang1]

Yo man help me out. This aint working

[@ashoktvm]

why is the music there?

[@mostinwilliams1310]

That is way too much my friend what about arrow up arrow down... Switch HDMI... Activate KZbin that is where arrow direction control and okay comes in handy...

[@ianjaeger]

Great content... but lose the background music.

[@someperson4712]

LOL!!! I had to comment as soon as I saw that he is using the same remote as me!!! Finally I might get helo

[@joking_oregon1]

SomePerson47 alot of people use the same remote

[@dwaynecrichlow5532]

Alexa! Turn down his damn music.

[@kevinzhong755]

You are great

[@benexmartsmarthome402]

Well this is excellent.But would you can try one of our products,I belive it could be so nice.

[@deniseholloway]

MUSIC IS WAY TO LOUD! tfs

[@joking_oregon1]

I velcroed my remotes to my wall

[@TheVideoZombie]

shut the music off man :D

[@gamerboy-pq3qc]

Do google nest

[@joey77jl]

Next time don't have a background song.

[@mvoakes8405]

yes, I agree Music very annoying

[@richardwalker4015]

Who else though this was a simple connection????😤

[@gamerboy-pq3qc]

Do google one

[@rafaelcid]

the music along the video is pretty annoying

[@markjacksmarkjacks]

The music is super annoying.

[@josephmanley2781]

dont play music on vids like this.

[@Tc-tb2iu]

Stop the music ffs

[@loveshchauhan5660]

We r not TONY STARK bro make it simple

[@joking_oregon1]

lovesh chauhan Dude you don't need to be Tony Stark to understand this , you don't even need to be Peter Parker to understand it.

[@alambe7275]

too much crazy!

[@brckhmptn]

Yh boi

[@annw-fitz4412]

WTF??

[@manuelcampos5169]

You're really cute :v
