Need help with programming on Blynk

Hello everyone

I have a problem with programming an esp32 with the app blynk.

So i have a setup with plc input signals of 24V that are connected with relais that convert the signal to 5V outputs for my esp 32.

I'm trying to program inside arduino. When an plc input is 1, that a led on the app Blynk wil turn on so that i know that the input was pushed. This with 16 inputs of the plc that are connected to 16 pins on my esp 32 with 5V DC. So i have 16 leds on the app blynk that can turn on.

I already started with the guide on the website of Blynk itself. But i can't find anything as an example of how i have to program that the led will turn on inside the app if the input valeu is 5VDC or 1

I hope this explanation of my start of this project is a bit clear to you guys and that someone here can help me :smiley:

thanks :)))

Just use your favorite search engine to look for examples. e.g. https://examples.blynk.cc/?board=ESP8266&shield=ESP8266%20WiFi&example=Widgets%2FLED%2FLED_StatusOfButton

The only issue may be to ensure that they're recent - I think Blynk has gone through a substantial revision since I last used it.
