Hello friends how are you?
I want to ask you about if I can make a push button that control by 4 pins in board thank you…
If you mean a button widget to control four pins then yes.
Attach your widget button to a virtual pin then in the corresponding BLYNK_WRITE(vPin)
function you control your pins using digitalWrite
commands.
Don’t forget to define your pins as ouputs in void setup using pinMode
statements.
Pete.
