}
}
but I not sure
BLYNK_READ(5) { // Usually, you will need to respond with a virtual pin value. Blynk.virtualWrite(5, some_value); }
how I can get the pin value number in this case 123456…
the proyect is count parts with a inductive sensor and display the numbers with blynk app
the pin reads state, the sensor this high and add a number in sequence 1.2.3.4.5
As mentioned, please edit your post so that your code is formatted correctly. It is very hard to read as is.
How fast do the parts appear? Sounds like a good use for an interrupt routine.
Here is an example semi based off the Push Notification Button example on the Sketch Builder. It is Untested so no guarantees it will work, as I don’t use interrupts all to often. Also be aware of switch bounce, depending on how the sensor works this may or may not be a problem.
