Yes 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?

Umesh Lokhande•9/26/24, 2:28 PM

what 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!

aymen ammari•9/27/24, 10:12 AM

Yes, 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.

Other solution are welcome!

Umesh Lokhande•9/28/24, 7:46 AM

To 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!
