How to do one function while button pressed and another function while not pressed?

in General Discussion • Other • 1 year ago

Hi,

I am making some software for my project. I got an RC car witch is controlled by an arduino, and I need some software to controll it, and a tip I got from a friend was processing. But, I have no idea how to make this code. So I ask for help.

What I need is;
When a button is pressed on the keyboard, example "w" one function starts. But when I release the button, a another function starts. In the arduino code I got one function for forward and one for stop forward. So when I press the button, the forward function starts, and when I release the button, the stop forward starts. Hope you understand.

So, what should I do?

Best regards,
The Crusher

That's fairly simple, it involves an if statement.
Inside draw():

if(keyPressed && key == "w") {
forward();
} else {
backward();
}

Hi,

Thanks for your reply. Looks really simple! I have never used processing before, but it looks like I am going to use it for now.
Is it possible to make it send a key while the key is pressed and another key when it is not? Like when pressed, it sends the key a to the arduino wireless and when it is not pressed it sends b? If so, I can make the processing code controll the arduino code.
