I have a simple problem. How do you clear the text in a Text Input widget such that the HINT text re-appears.
I tried writing a “” but that does nothing e.g.
I tried putting in a space i.e " " e,g,.
Blynk.virtualWrite(V1, " "); but the HINT does not re-appear as their is a space int he INPUT.
Anyone know any tricks - nothing I can see in the docs ?
