Arduino Documentation sucks, ChatGPT couldn't understand my issue, Google just doesn't care. You are a savior my friend.

Man, you're great. Merry Christmas and thank you. It's nice to see someone that wants to help :)

Great tutorial! I think the traffic light included with the Ultimate kit can potentially damage your Arduino pins because the included 330 Ohm resistors are too weak and they can allow currents higher than the 8 mA the Arduino Uno R4 can safely give through a pin. I think adding an extra in series resistors is the safe approach when using the traffic light include with the kit, one 220 Ohm resistor for each pin should do it. What do you think ?

Cảm ơn bạn đã chia sẻ video chi tiết rõ ràng rất bổ ít ❤❤❤

Very clear outstanding

There is no power source that comes for the breadboard. It comes with a 9v battery but the only connector is to the Arduino itself. I'd have to snip off the batter connector and strip the wires to work with the breadboard. But then I have no 9v source for the arduino.

Kind of a bummer that the kit I bought points me to this tutorial but the kit has no resistors or LEDs. The video must use the 3 in 1 kit where I just got the regular ultimate sensor kit. "Ultimate" makes me think "ultimate" but I guess there's an "ultimater" kit available.

Thanks

Can I use esp32 cam?

Wow! I came here to learn how to use millis so that I could run the 4-digit, 7 segment display along with other modules. I learned so much more than I anticipated ; simple little things that I hadn't even thought of, such as using a for loop to assign all pins of the same type. I'm using an ESP32 and my pin numbers are not in order, but I can just use an array and loop through the elements to do the assigning. There were several other things I learned. You've earned my sub; and I really enjoy your style of delivery.

We definitely need a state machine.🤓

Looking for the solution to the challenge of lesson 6. I cannot figure out how to get that done. Thanks.

The official Arduino doc wasn't this helpful and thorough. Keep it up!

How difficult would it be to port to use the EspressIF environment (Eclipse+IDF Plugin) ? I have an ESP32-C3 board, and installed the Espressif Framework.. not sure how easy Arduino is.. but after much trial and error I am single stepping thru a hello world project working in IDF! Now, I'd like to setup the ESP32 as both a webserver (station mode) and Access Point mode (hotspot), such that the ESP32 data broadcasts its data using WebSockets to any connected clients/browsers.. although , I understand AJAX is also popular (javascript can use XMLHttpRequest to fetch /data every second and update a portion of the page (R"rawliteral).

Awesome bro

Galing Bro!

well done! will you address the use of wifi? please do so! thanks in advance!!!

ledcSetup function no longer supported,so what to replace it with???

This is very good

Strange and amazing. I found this the day I failed at adding millis function to second task. After days if researching how to multi task without delay I found only videos with millis function being added to one task. Today, i tried to add to second task and failed. Now this video pops up. They got the algorithm down to even the process of users learning a system

Much appreciated... Thank you for a well structured tutorial.

This is something I have been trying to learn but little time. Most of the time, I can read the code, sometimes I get lost. One problem I am having is reading analog values in the ESP32 web server mode. I seen it done in android and firebase but not in the webserver.

may i ask this uno r4 and ide will work on microsoft surface 11 pro (snapdragon x plus)?

So there's also a library where the code is already program and all you have to do is copy and paste it? and then just do some tweaks if you need to adjust this and that? I love your contents btw! Once i'm back in the US, will definitely try some projects from your content.

I wish i learn how to code when i was still young. i just love projects like this. i'm trying my best to learn Python little by little right now so i can learn how to atleast read the codes and follow other content creators instruction like this one. are you Filipino Sir?

Can you pl give us an Arduino projects to monitoring the storage tank water level...??

Super well done! I hope lots of people find your videos so you keep making more. Thank you.

Sir do u have repositiory on github or something for the code ?

Thank you for you excellent ARRAY study.

Hi, is this course complete? Or will there be more in this series?

Thank you

Baket po hindi ako maka connect sa firebase sabe po sakin na kulang dw yung mga credentials ko nilagay ko nmn po yung api key and link sa database pero kulang daw mga credentials ko

please provide code sir

Can you tell me where the SSD1036_SWITCHCAPVCC is defined? I have this error

Hi Joed, Excellent tutorial and extremely satisfied with your channel. However I have uploaded the code and the serial monitor states that http started. However the website 192.168.1.1 was being used by my router. I change to 192.168.1.2 no success also tried 192.168.1.3, 192.168.2.1 and last 192.168.1.121 no success on all of them. Can you please give me an answer what address I will use. I also copied the address to the subnet to all of the addresses. Thanks

Now with this what about a RTC for desplaying? Thanks.

Hello, thank so much for this video but i wanted some help. Can i just make the code on arduino ide app then store the data on firebase and at the same time represent this data of iot cloud or any web or mobile app? if so can you give me advice me how to do it.

Hi Joed, I could'nt get this to work. I'm getting a message a compilation error "expected primary-expression before "=" token. Sorry I'm just new to this coding.

Thank you for your very informative tutorial. I have been trying my ESP32 to work but I could not find any you tube channel content that can control this ESP32 . Your the only one that works tried your episode 1 it's excellent. Now I'll this one and let you know if it works for me. But I'm confident that it will work. Thank you again

where is the answer of your activities tho?

Hi I really like this playlist because I'm working on a project with Arduino Uno R4 and Adafuit io, I really hope you continue with these videos soon.

Good evening sir what library should i use on wifi and firebase library using Arduino Uno R4 Wifi? Thank you Sir.

Ohhh, free wifi! Don't think it'll reach all the way to Europe though. :p

Thanks for the video. Note that I think you should have made it clearer that the 'LOW' mode of invoking the ISR blocks completely all the rest of the loop() code during the complete time the button is pressed, which makes it almost useless in real life. Instead of making long example where you merely illustrate by example how the library method works, I think it would be more helpfull, especially to beginner coders out there, if you explained how we should use the ISR in a real-life situation. In other words, we want to learn from your experience more that just what are the library options.

Thankyou so much it is really helps me . Keep it up

Nice. Thanks JOED

I'm going to view and like every video starting with this one and subscribe to your channel. It's not much but your videos should get more reach. Thank you for sharing your time and knowledge with us!

Sir magkano po ang sunfounder na kit?

Thankyou ❤
