Thank You sir, but somehow I was able to solve that previous issue, Now I am struggling to change menu option using array
My project is Car PARKING MANAGEMENT SYSTEM WITH BOOKING
SO I need to do this
{Blynk.setProperty(V20, "labels", slot1>0?"slot1":"" , slot2>0?"slot2":"" , slot3>0?"slot3":"" , slot4>0?"slot4":"" ); }
But problem is how to pass a empty/NO/NULL value to menu.
by passing “” it shows item3 in menu widget
Here slot1,slot2 etc contains either 0 or 255 data via IR sensor like below
