Hello Sir, Can you please tell if I have to install drivers etc for my ESP 32 Wroom (30 pin) and if yess which?

[hithushmohanaraja]

Hi.is 5v enough to operate the sensor? The reading is always zero when i did this.

[kalyanidwivedi]

I am getting this error while compiling using NodeMCU ESP8266 board

"Error compiling for board NodeMCU 1.0 (ESP-12E Module)"

[ded]

does the phone need to be connected to the same wifi?

[sreeharip]

I need to sense water level using esp8266...can i use this code

[kenechukwumodebelu]

Could we use Bluetooth connection to measure instead of WIFI?

[mohamedhassen]

Hi, the code is giving an error as follow:
'BLYNK_DEVICE_NAME' was not declared in this scope

[robertburgess]

I ran the code an this error appears:
A fatal error occurred: Unable to verify flash chip connection (Packet content transfer stopped (received 6 bytes)).
Failed uploading: uploading error: exit status 2

Sir, I included the blynk library in the arduino IDE but instead of it, shows the error - BlynkEdgent.h:No such file or directory . Please help

[_SurajYadav-lrfl]

hello sir my readings of ultrasonic sensor is showing 0cm I don't know what's wrong with my project. when I'm using same Ultrasonic sensor with arduino it is working but in case of node mcu it is only showing 0 cm . even my node mcu is successfully connected to wifi and send data to thingspeak website, please sir help me I'm not able to recognize my mistake

[edwinbenny]

Sir the wifi isn't showing
I have done everything earlier but now i couldn't find the wifi from the esp32

[andystevens]

How accurate is the distance measurement? Have you checked it with a distance tape/ruler?

[satyamjha]

Hi, the code is giving an error as follow:
#include "BlynkEdgent.h"

compilation terminated.

exit status 1

Compilation error: BlynkEdgent.h: No such file or directory I have made sure that i installed the library you showed in the video, even then its not working correctly pls help.

[nilimakashbaruah]

I am getting error in the code . Is the code correct.?

[nba]

sir how to change the ssid I cannot find where it is if use blynkedgent

[gururajesh]

Code for Esp8266 is not opening when downloaded, can you do something

[chinmayitutorials]

sir i'm getting the error i.e blynkEdgent.h no such file exists. i also installed new version blynk library

[nishatvasker]

Sir can you please provide ESP8266 code for this project

[kenishida]

Hi sir, i wanna ask is it possible to run using 1 board of esp8266 with 2 difference sensor like IR and Ultrasonic sensor.? does the board detect those 2 sensors if i run in 1 board which is esp8266.

[farukozgur]

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
