How to install wifi board ESPxx series to Arduino IDE, Sir.

[a_rahul_krishnan]

Sir im getting this error:

user_interface.h: No such file or directory

[SMEDehradun]

Hello Guys,
I have made few changes in the NodeMCU code to connect with New Blynk. you can download from the video description.
Also added the programming Code for ESP32 As well. link is available in the video description.

Sir I brought a tds sensor from xcluma. But after placing it in brine solution, it is showing a value of 0ppm. Sir what should I do and is there any way to calibrate it. If so please help me, I have mini project tomorrow

[SMEDehradun]

hello guys,
if anyone want to add Gauge or Graph in the blynk for any analog or float data, then follow below instructions:
To add Graphical chart in blynk, then you can select the superchart. For that, you need to go to blynk mobile dahsboard, then go to the blynk widget by clicking on + sign. scroll below and you will get the super chart. click on that. it will be added to your template dashboard. now click on it and in the property, you will get the datastream. we can add only 1 chart on free version. click on the sign that is lookalike music visual adjuster. once clicked, you will get the option to select datastream. select the virtual pin of
tds value and its done. back to dashboard and you can get your values on super chart.

Same process, you can follow for the Gauge.

Thank you so much brother, very nice video

[india_poco_x]

Sir how to display in dashboard whether the water is good or excellent or poor and turn on water purifier (use dc motor to demonstrate)

[india_poco_x]

❌The nodemcu has 3v output will it work,
What resistor I have to use sir? ❌

[sejalvetkar]

Sir, are the connections same for node mcu?

[ratulyajee]

Can I continuous monitor tds on bylnk and when the tds will go high then it will send a led blink

[sayanaxavier]

Is the code given in the description for esp 32 module

[rayenkhaled]

Hi sir, why are you connect the pin of the TDS sensor with 5 volt and you just put 3.3 as voltage ref in the code ? please i need help !

[nurulnajihabintiabdulsamad]

Sir, at the end of the video, shows that we need to connect the USB cable to nuttyfi and connect it to the computer's USB right. So why do we need to that? or it is because we want to power up the nuttyfi?

After this, , if we want to check the temp. or pH again, do we need to connect the sensor to the coding or we can just only use the blynk apps? and how to check it? do we need to connect it with the coding again?

[animist_studios]

sir
extern "C" {
#include "user_interface.h"


void app_loop();
}
Compilation error: user_interface.h: No such file or directory this error occured in this part of the code

[sejalvetkar]

Hi, Will it work with 3V, because the node mcu only contains 3V pin

[bradleyjim]

Hi sir, do I need to use any resistor for both TDS and Temperature sensor if I want to connect it with my esp32 board?

[someshdeshmukh-yefi]

Sir
In the programme TempRead function is not decleared

[joshuaolivo]

Hello sir Good day I'm done with my connection using NodeMCU. In your circuit there is a resistor.. Do I need to use resistor also using NodeMCU in replacement to NuttyFi? Thanks for your response

[shafaanuar]

Hello Sir, can i connect pH sensor and soil moisture sensor to A0 pin at nodemcu? I mean 2 sensors using the same pin which is A0, can i?

[amulya_minnie]

Sir, I didn't find the code for esp8266 and when I run the code it's showing as tempread is not defined in the scope. What should I do sir ?
