PUSH BUTTON

Hello,

i am new to arduino, i am interested to modify push button program for single button to 3 button.

Example,

in original program we can on/off led or load by single button, but in my case i want to control light/load

by three button, if i press 3 button same time than only led should on.

please give me some idea.

Well for a start we don't know what "push button program" you're talking about, so you should post that first

If (!buttonA && !buttonB && !buttonC)
Do whatever you want to do

Assuming input is tied to 5v and switch goes to gnd.

This means "if all 3 switches are low" do whatever.
