I just came across this video. Awesome video and explanation. I am working on building a variable bench power supply with a computer interface. I would like to display/change the values both on the power supply and also on the computer screen. I’m looking forward to watching your current and any new videos. Keep up the great work!
Dear Ahmed, Nice work as always. Plz make a video on a project... DHT sensor connected with UNO and Esp mudule can read it and can show both temp and humidity to blynk server. Regards
@@robojax thanks for response. Blynk is very useful and very friendly. I used it in my many projects... I am planning to use STM32 microcontroller and esp8266 for one of my Chicken egg Hetchery project but issue is to interfacing esp8266 with it or UNO...
I just check it it is a scam. Pay for simple connection? really? I am working on platform that offers free. snipboard.io/vuWIO5.jpg will never promote this. Students should learn at least with 5 devices and 10 to 20 projects should be absolutely free.
why people pay for "blynk"? I am amazed. It should be free. Unless I find something that offer some basic FREE features, I will not sure or try to use this kind of service.
Hello Ahmet, verry interesting ! Can you please explain me, how can i measure and display positive and negative Voltage. I looking for a solution to measure +12Volt to -12Volt ? Do you can help me please?
The first thing you need to do is level-translate the input voltage so that -12V corresponds to 0V at the ADC input, and that +12V corresponds to 3.3V at ADC input. In reality, you should include -13V to +13V as a range in order to see the voltage slightly above 12V. First you need to split the 3.3V in half, and use that half point as 0V. Then you need a resistive voltage divider to drop 13V to 1.65V. Finally, you need to reflect that in the code, so that the code would make 0V into -13V, 1.65V into 0V, and 3.3V into +13V and appropriately space or multiply any of the voltages in between. I know the analog part, but I don't know how to do it in the code yet.
Hello, thank you for the great video, I think everyone is playing catch up with these ESP32 boards, abit different from the regular Arduino setup. My question is, I'm using the ESP32 wrover-dev. That has a 3.3&5v output. Can 5v be used for a pot if the voltage level is changed in the code? And what pin is best for output, to actually actuate with the pot? Thank you much.
hello, to read pot, I have shown all pins that are available to be used in this same video. Here is full introduction video to ESP32 ua-cam.com/video/--Fj8QDlGuQ/v-deo.html where I have shown pins for power supply and all specs. I have not make any video on analog output yet.
Thanks for video. You have made explanations that will make the esp32 pins, which are difficult to understand, more understandable. I have a question; If analog pins are used, that is; If pins A0, A1, A2, A3, A4 are full, which other pins can we use for analog input?
Sir, I asked ... I once bought a module so I used esp 32 dev kit ... now I noticed that the V in was 12 Voltdc ... as far as I know the standard is 3.3 / 5 volts ... So how about that, the one using 12 Volts and it turns out to be durable until now ... what is the standard voltage?

AMAZINGGGGGGGGGGGGGGGGGGGGGGGGGGGG PROOOO KEEEEEEEP GOOOOOOOOOOOOOOOO
Can you do a video on how to program the basics of Wesmos D1 R32? Like turning an led on or off etc.
Just search my channel. I have it. Here is how to Gina d a video in a channel ua-cam.com/video/OhkUceBWcHs/v-deo.html
Dear Ahmed,
Nice work as always.
Plz make a video on a project...
DHT sensor connected with UNO and Esp mudule can read it and can show both temp and humidity to blynk server.

Thank you Ehtesham. I never heard of blynk. Just checked it. How do you use it? it is not free.
@@robojax thanks for response.
Blynk is very useful and very friendly. I used it in my many projects...
I am planning to use STM32 microcontroller and esp8266 for one of my Chicken egg Hetchery project but issue is to interfacing esp8266 with it or UNO...

I m having nodemcu..
I have input from level transmitter 1-5V need to convert 0 - 100% water level from blynk app morning gauge please do the needful
why people pay for "blynk"? I am amazed. It should be free. Unless I find something that offer some basic FREE features, I will not sure or try to use this kind of service.
@@robojax - what do you use / reccomend in place of Blynk?
I don't know. I've spent 1000s of hours of my time offering this for free. I have to see.
Reading is not accurately, if we measure 0V to 15V using this method.
Please make video using
ads1115, esp32, and LCD16*2
For DC monitoring.
it is 12bits and for most applications it is very accurate.
How to read 5v sensor with esp32?
what is "5v sensor"? this is the video to read 5V.

hi. no pinMode in setup?
Please watch introduction to this module. Search my channel
Is it possible to use analogRead in any analog pin in esp32
(unlike ledcWrite)
I belive I have mentioned which pins can be use for analog reading.
Super merci,possible de faire la même montage coupler avec un OLED ?
Je vous en prie. J'ai une vidéo sur OLED avec ESP32 ua-cam.com/video/dk-01OpKYuQ/v-deo.html. Mais je vais faire une vidéo séparée sur ce
@@robojax Merci!
