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. #esp32 #nodemcu #esp8266 #TDS

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.

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?

@SMEDehradun Жыл бұрын

We use the usb for 2 purpose basically- one for uploading the program & another is to provide power. Right. And once we upload the program to out any board, then that program stored in the memory of that board. We don’t need to upload it again and again. Once program uploading done, then just provide the power to your board and it will work all the time as per your code.

Once you upload the program to NodeMCU, it’s permanently stored it in NodeMCU. Once you power the NodeMCU, it will be automatically connect to blynk. If not, then there can be power problem in your circuit. Verify your connection & program again.
