I was just wondering how to fix my code, actually it's super easy now, thank you very much

Can you please show me how to use the "numeric input" function to input a setpoint via the Blynk app. There are no tutorials videos online for that feature.

Also, if i use the "numeric input" feature, would I be able to input a setpoint temperature for example 25 degrees celcius, instead of having to input a numeric value within the range of 0 to 255?

Is there a way to make the LED bigger? Your entire label is not visible in the Blynk app, and mine is not either. Buttons can be stretched, and wish I could do that with LEDs to make label visible.
