Text with digital pins

[jbolfiil]

I am trying to display text based on that status of a couple of digital pins… I am having more trouble than I thought I would have. How do you check the digital pin?

if(digitalRead(pinNumber))

{

tv.print(50, 50, "text");

}

else

{

tv.print(50, 50, "something else");

}

I have tried this but the there is no change in the text when I tie 5V or ground to that pin. Yes, I am also doing “pinMode(pinNumber, INPUT)” in the void Setup(). I have looked up the information on digital pins on the Arduino website a lot but I still can’t understand…
What am I doing wrong?

Also, what is a good base code to start with? I downloaded some of the project but I don’t know what is necessary and not necessary with the registers, timers, etc.

Like I said, all I want to do is to display minimal, non-moving text depending on the digital pins so any help regarding that is appreciated!

Initialize with:

pinMode(pinNumber, INPUT_PULLUP);

This will tie the pin to 5V with a pullup resistor. To activate ground the pin and it will read LOW.

read with:

if (digitalRead(pinNumber) == HIGH) {

tv.print(50, 50, "text");

} else {

tv.print(50, 50, "something else");

}
