    I am using an FreeNove ESP32-WROVER-Dev board because that is what I have. I set the echo pin to 18 and trigpin to 19. I left pinmode on 34. I am also using the Board= "ESP32 Wrover Module" no idea if that is right... I don't even have any idea how you could know what is right. There is no option for Com port = 8, like you have. I have only one option: Port = COM1. When I plugged the esp32-wrover-dev micro USB to my computer and pushed the upload button I get "Compilation Error: BlynkEdgent.h: No such file or directory" any ideas?

    I'm trying to transfer the distance I get from hc-sr04 sensors to thingspeak using Nodemcu. Only when measuring distance the sensors work very well but when I write the code to transfer the data to thingspeak or firebase the sensors work very slowly. What could be the reason for this? how can i fix it

    • @SMEDehradun

      It may be due to the code you are sending to Thingspeak or firebase.
      You can make a separate function to send data to thinkspeak or firebase. & call it once it in 10 or 15 second. But measure the distance every second. Then you will get regular data from ultrasonic sensor

      @@yashshrikantjayale2807 Good night,
      I think I found the error, I just checked and had the same problem as you, correcting the error is simple, just copy the text, in the second command line which blynk provides, remove the word TEMPLATE , and replace by DEVICE:
      Blink gives you:
      #define BLYNK_TEMPLATE_ID "TM00000_0_000F"
      #define BLYNK_TEMPLATE_NAME "ProgName"
      The program requests:
      #define BLYNK_TEMPLATE_ID "TM00000_W_000F"
      #define BLYNK_DEVICE_NAME "ProgName"
      After that I managed to get it to work, hope I helped.
