AShould I send the code as well? Maybe the error is from it.
UOk cool. This is ESp-01 Module uses ESP8266Ex. To make this work you first have to make sure your ESP-01 responds to AT commands https://youtu.be/MPyShmRcgD0 and then using Tx, Rx on Arduino you can make it talk to IoT Server. Have you tested AT commands with your module to ensure its working? It's advisable ensure module works before you connect ESP-01 to Arduino or any board.
AYes, I tried it. I sent it AT and it sent me OK. I connected it to the Internet via AT+CWJAP and it connected to the Internet.
UGreat, are you planning to make an arduino to talk to blynk using ESP-01's Wi-Fi connectivity? I have once tested normal webserver hosted on Arduino using ESP-01. I suggest to stay with Arduino Uno to keep things simple than Mega. I remeber i spent countless hours in connections. These serial connections and power will drive crazy because you may need to add some additional passive components to make it work otherwise even code is right it will make ur life difficult. But for sure there are several videos on YT to help.
AYes I am planning to connect the project to the phone via blynk app with esp-01. Ok I have an Arduino Uno and I tried esp-01 on it and it worked. Now what should I do?
Uwhat else then not working? you just said it working with arduino uno? if your goal is to port with Mega then just change serial and try it will work for sure as it worked with Uno. Create Blynk account --> Create Template --> maybe you'll get some device credentials from cloud that you've to insert in code. Please read docs. Best wishes!

ASo I can install the project in a place and connect it to Wi-Fi via the web or an application without changing the code or writing the network name and password in the code
MYou could make the wifi board to act as a AP mode, host a webpage, using that scan the network, onces selected, change to STA moded, which will let it connect to the wifi network
AIs there a video or article about this? I want to read more, knowing that I only know how to program ESP32, ESP8266, and Arduino boards.

but this is possible in ESP32

AIs there a way to make the esp32 a wifi shield for the arduino uno and connect them in blynk?
AKnowing that I want the esp32 to work as a wifi AP
AYes, you can use the ESP32 as a Wi-Fi shield for the Arduino Uno to connect to Blynk. You'd need to use the ESP32 in a serial communication setup with the Arduino, allowing the Arduino to handle logic while the ESP32 manages Wi-Fi connectivity. The connection typically involves using the SoftwareSerial library on the Arduino to communicate with the ESP32 over RX/TX pins.
APlease is there a blog or video that explains this in detail so I can look at it?
Show to encrypt a code?(i will use my encrypted code to run the project and it will be public)

MHello @MCU, MPU & Firmware ,
Has anyone got a good guide for USB UAC 2?
Has anyone got a good guide for USB UAC 2?
MI have to create a sort of Audiorelay from my phone to a linux machine
My thought process was create a device with 2 USB port with UAC2 support where the 1 of the USB input gets connected to other port Output and vise versa
Other solution are welcome!

Do you know a way to make linux act as a USB Audio Device/peripheral for a USB Host? From which we can access the IO Audio stream from Host using gstreamer/pyaudio?

AI have a project on Arduino Uno with ESP-01 that I connected to Blynk. When changing the password and the name of the Wi-Fi network, I need to change the code... I want this to be done via the web. What should I do?
MOh,
This seems to be exactly what i wanted as a soln
I have rpi 4, WIll test this out and let you know,

MU could a webserver from which u can input your desired passwd, save that as a variable
Then reset the AP mode and then begin AP mode with new passwd variable

I am thinking more from a perspective if i want to produce such products in scale and volumes. I will not be able to sell it as-is. Each and every device has to have the n/w credentials hard coded. We will not be able to make it as a product, wherein you buy the programmed device and the user just plugs in and get started after setting their ow...

AI want to design an iot water quantity monitoring by esp32 that contains TDS, Turbidity, temperature, ph and water flow sensors. What parts and connections do you recommend and what additional parts do I need to build a complete system like this?
AWhat is the best IOT platform to do this project on?
UTo keep things simple in the beginning I'd suggest use ESP32 to interface sensors and manage WiFi capabilities. There are enough analog and digital pins to handle h/w interfaces. For sensor selection, you may need to research online to ensure that they serve the purpose (compare power consumption, nature of analog output, cost, handling complexity to achieve accuracy/calibration). As fas as IoT platform goes stay with Blynk which offers a web dashboard and mobile apps with multi-user access. There are also plenty of videos on YT to help you get started. Best wishes!

AI have a project connected to Arduino Uno with ESP-01 for Wi-Fi and it is controlled via the Blynk platform. I want to write the Wi-Fi network name and password externally via webserver and not inside the code. Is there a method, video, article, research or someone who can help me with this? I am in dire need of help.
