Hi,  
welcome to the processing forum !

You have actually some errors in your code when using the `keypressed` function. It does not actually expect any parameters, and you get the key by either `keyCode` either `value` (only in keyPressed). Take a look there : [reference | p5.js](https://p5js.org/reference/#/p5/keyPressed)
