Hi there,
Is it possible to trigger an if statement with a button, if it's possible please help. On my design project I want the the set of code to exist if only I press the button and if the button is not pressed it should not be executed, please help I have 4 days left to present my project and it's incomplete. Here is the code that I want to control with the push button:
if(int(flowRate) > 4)
{
digitalWrite(SolePin, High);
led.setCursor(1, 0);
led.print(''Warning'');
}
I want this action to happen if the button is pressed, please help, 
Buttons are normally just open or closed, so a HIGH or LOW value is returned.
If you have this in setup:
void setup(){
pinMode(buttonPin, INPUT_PULLUP); // button connects pin to GND when pressed
} // end setup
Then in loop you can do this:
void loop(){
if (digitalRead(buttonPin) == LOW){
// button is pressed, do something
}
else { // button is HIGH
// button is not pressed, do something else
}
} // end loop
Don't forget you also need to debounce the button (or have a long enough delay between reads) that you don't get hit with multiple button presses when you push the button and the contacts bounce (as most buttons do).
Thank you guys,
I presented my problem incorrectly, What I needed is that, is it possible to have a if statement that has two conditional statements on it, ie, if(a==0; B==0) { // code to be executed if both A and B conditions are true}, The first condition will be based on the button and the second one will be on the my system.

They already answered the question. 
I think that with OR it should be something like "||" instead of the "&&" but I'm new to arduino IDE so I'm not sure.
Hope that helps.
Replied to your other thread with the same Question.
