thank you bhaiya , multiple sensors ka data ko thingspeakserver par kaise send karenge bhaiya is par bhi video bana dijiye , aur vo data website par kaise show kar sakate hai
Okay sure, pakka video banyenge
I dont understand. Even when I follow everything you did step by step including code, The outcome is just "..........." in the serial monitor. Thingspeak does not record anything and nothing happens after it finished uploading the code into the nodemcu.
Have you changed the WiFi name and password
@@TechForFunOfficial Yes i have. As well as changing the API link/key towards my Thingspeak channel. All it does is just "......." Could this be a hardware problem? Because I have read that HC-SR04 needs 5V source but the Nodemcu only has a 3V pin and the VIn.
@woodenchopsticks9166 you can connect to vin pin
After a long time I finally got another sensor, nodemcu and an arduino. Safe to say It wont do anything if I plug it into the Vin or 3.3V. I used the arduino to supply the sonic. Everything else works fine though its just underpowered. Dont understand how you make yours work with 3 volts because nodemcu can only safely supply 3v. Unless u voltage amplify .
can u provide the code please
