I wanted to ask one question, The virtual pins you used in the app, how is the blynk app able to auto connect to the variables that hold the actual data of temperature and humidity in the esp board? Maybe some code you edited in the IDE and didnt mention?
Hi there, the code i uploaded did not do this! Thanks for pointing this out, I have added a link to a corrected sketch, hopefully this answers your question
Ok, thanks for the quick reply! Now it makes sense. "Blynk.virtualWrite(V4, t);" is what i was looking for :) thanks alot, now i can proceed to my project!
hello, sir need help with Blynk app here, I connect my two sensors which is temperature and ph sensor to esp32 dev board. the problem is my blynk app keeps telling me the value is 1 until 999 and so on for both sensor. but when i click on serial monitor at arduino ide the reading is ok. what is the problem? is it because of coding? please help me sir because i need to submit my work ASAP. i am using Blynk.virtualWrite(V5, millis() / 1000); for temp Blynk.virtualWrite(V56 millis() / 1000); for ph
What are you printing in the serial monitor? I imagine it's something to do with Blynk converting to a string, try writing a pre-formatted string to Blynk.
@@cabuu4122 yeah, i figured it out a couple of week ago. its my declaration at Blynk.virtualWrite(V5, millis() / 1000); it should be Blynk.virtualWrite(V5, temp);
hello sir, can u make tutorial with esp32 with pH sensor and monitor using blynk? oh yeah! one more, esp32 and TTGO esp32(built in LoRa) can use the same coding?
