Nice. Thanks JOED

Sir Good Evening po ano gagamitin na library sa uno r4 wifi to connect to firebase and wifi? Thank you po.

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 ❤

I need to retrieve data from firebase to Esp32. The authentication works and posting data works but I need to read data for signed in user

Great work sir thanks

Sir, please make tutorials series about this robotics car..

Very helpful video. If you have problems by compiling the scetch please mind that the LEDC declaration / API was changed in the latest version (ledcSetup and ledcAttachPin is now ledcAttach).

Excellent tutorial!

Thankyou very much! I, it seems, did according to your project about 5 years ago and now i found it again, but already on a new controller and it already works!

Sir ,can you post the complete code ? thanks you very much ! great video

Hello, student here! May i know the code. We'll use it for our project. Thanks. It will help Alot!

this was explained so well! thank you!

Thank you so much, this video was very helpful and really well put together. Maraming Salamat Po!

SIR i have encountered this in serial MOnitor "Failed to send data to Firebase. token is not ready (revoked or expired)" badly needed thanks

Thank you for the excellent tutorial and clear explanation!

Can you maybe do this for an app with flutter?

Seems like a block of code is put out there, then everyone does it exactly the same. I would use a different approach. Simply use one variable such as Blink Blink=millis()+Millisecond interval you desire. millis()+1000=every second. then just check if millis()>Blink IF yes then check if pin is high or low and take appropriate action with your IF ELSE, if high set low and if low set it high. Then just put Blink=millis()+1000 just before exiting your if statement when you checked if millis() was > Blink.

Thank you very much, it works now Was trying for around 8 hours, with different libraries and clients, and none of them worked, but finally, in the end, this works

I've been binging your videos. They are really nice and informative. May we also have a tutorial about RTOS? Along with interrupts, I think this is also a very good and must see for beginners like us since we are stuck in a somewhat "linear" flow of our programs for our projects. I'm subscribing, hoping to see more content from you especially other micro controllers like STM32 and ESP32 even tackle other peripherals/lines like CAN and DMA. Thanks for the video!

Alright, you've earned a subscriber! I like that your actually explaining the code instead of just saying "copy and paste this" like so many UA-camrs.

How we can reset millis(), after 50 days it will be overflow !!!

اللي جي من عند محمود مجدي يجي هنا 😂😂😂❤ واللي مش فاهم يفعل الترجمه على الفيد

Good Day sir , Ask lang po kung same method rin po kaya siya sa Raspberry Pi 4 ?? Thanks in advance po

Any car Crank and cam signal how to make code explain please

How to make car Crank and cam sensor signal timerone use explain please

Thank you for this knowledgeable content.

I received my SunFounder Ultimate Sensor Kit the other day and my Photoresistor Module only has 3 pins (VCC, Ground & DO). Can I get an updated sigmatic and code to use?

I really enjoy your teaching style. I have myself and my students using these tutorials for learning how to use sensors, LEDs, motors, sound and pneumatics for animatronics. You do an amazing job as a teacher. Thank you so much.

Your esp32 always showed as offline. At what point did you bring it online. Thanks.

Vest tutorial, thank you. i will comtinui your tutorialsl. I also bought tlhe kit 2 weeks ago. so i cane scros you tutorials.

I'm using atmega and stepper driver for nema42. The problème I'm facing is big interférences wich disturbs arduino. Inputs become random even i use an external pullup resistor of 10k. The project works perfectly when the motor is off. How to fix EMI in this case. Note that in my project, i'm using two motors, a stepper nema42 and a 0.5kw 3 phase motor.

Thanks for your well explained videos. Do you have any videos on handling and parsing serial communication?

you're a very good teacher, and this was an enjoyable and educational video!

Thank you

Thank you for the video sir, but what can i add to my code to see the ledcSetup() function so I can be able to compile and upload my code on the ide?

Awesome

You are awesome in explaining the concepts

Hello, thank you for this beautiful video. I'm a novice and I'm stuck doing the exercise. in the example the on and off time of the LED is the same, if I code the same principle for another LED, the first LED also lights up even though it should not. the off time of the first LED must be longer than the on time so that the second LED can light up in turn, and I don't know which line of code to intervene. where is the answer to the solution and sorry for my broken english. thank you

hello sir, my oled is SH1106,SSD1306 lib are not compatible

In my case, every time that I read a value from firebase a lot of times, the esp3 gets frozen for 1 min. Why does this happen?

Hi, need help. When I’m connecting my R4 Wi-Fi to my laptop, power and L Led are lighting up but windows is not detecting board and not assigned any com port. I’m using latest IDE and installed R4 board in it. What to do?

لطفا به من بگو برای رفع خطای پریویو چیکارکنم لطفا

Excellent description of Analog and Digital sensors. I tried using "bmp.readTemperature(true);" for the BMP280 sensor to get the Fahrenheit reading (like we used "dht11.readTemperature(true);" for the DHT 11 sensor), but it didn't work. Oh well, thought I'd give it a shot. I've enjoyed both this series and the "Arduino UNO R4 Minima" lessons. I look forward to the next lesson(s). Thank you!

I appreciate the thorough explanations. Thank you.

This has been very helpful. Thank you.

This was a very helpful lesson. Thank you.
