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)

NOnly one hour until our event: Getting Started: Choosing the Right IoT Hardware Platform to Jumpstart Your Design
We’ll explore the top development boards and help you choose the best one for your next design.
We’ll cover the pros and cons of platforms like:
- BeagleBoard/Bone
- Arduino Portfolio
- Raspberry Pi
- Espressif
- Adafruit Ecosystems

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!

MHello @Ming,
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,

all this time, i was thinking on how will i fool a Host to think that rpi is a peripheral

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.

In this guide you'll learn how to use WiFiManager with the ESP8266 board. WiFiManager allows you to connect your ESP8266 to different Access Points (AP) without having to hard-code and upload new code to your board. Additionally, you can also add custom parameters (variables) and manage multiple SSID connections.

AI have a project connected to the ESP32. The TDS sensor in it does not give correct values. It gives values of approximately 450 ppm for a liquid with a value of 940 ppm. What is the solution?
MDid you calibrate it?
AHow do I calibrate it, knowing that I entered the temperature value by connecting the max6675 sensor and used the code on this site for the tds sensor meter?

XHello, web dev here! I'm looking into learning about embedded programming and have decided that a simple RTOS from scratch would be my project. I have no interest in doing anything useful with the final product, the moment I get 80% - 95% of learning value I plan stopping and learning mech-eng. I have a RP 4 that would make for a good final boss but I don't know what to buy as a tutorial and any other equipment?
B@Xar like you need ideas ??
XYeah like what microprocessor and other stuff to buy
Bbut you don't have the project idea
XThe idea was to build an RTOS from scratch
MIf you really want to save money, you could try qemu
XGood to know, I do have a budget of $100 or so.
MQemu is free
MBut if you want a feel of real world hardware,
100$ is a decent to buy variety good amount.
You could start with a any STM32 NUCLEO Board
Preferrebly the stm32f0 or f4
There are cheaper alternatives like esp32

Zthey just took 20 yrs to land rtos features in linux, if you plan on building an RTOS its best to focus on micro controllers
