Ive been using Arduino for a technology class my high school provides. Im fairly new too Arduino and programming in general. Im trying to program the IR Remote to send the signals to the LCD display and display baseball home and away scores. The goal is that when I press the VOL+ button, it adds 1 to the home score, and when the VOL- is press, it does the same to the away team. So far, the code adds one point to both teams. the other problem is that it happens when any button is pressed. If I could receive some outside help from someone who knows Arduino, that would be very helpful.

Can you clarify what you mean by the "Whoops!"?

Oops . Means you did something wrong/silly

How do you compare two values in C ?
