Hi! I'm new in the Arduino world and I'm trying to build a midi controller but I'm having some issues. I'm following this video
and using the same code. the guy there uses an old phone keypad as one of the components. From my understanding most keypads are wired with a wire coming from each column and each line but the keypad that y got is wired different so when I connec only some of the keys work. So my question is how should I connect it to the Arduino (I'm using a mega) for it to work? Or should I change something in the code?
I'll leave a picture of the phone and the keypad I'm using where you can see how it's wired
And here is the part of the code regarding the keypad theMIDInator/readKeyPad.ino at master · SwitchAndLever/theMIDInator · GitHub
