6 button arcade .ino

Projects Programming
1

G'Day All,

As a project with my kids we have made up one of the Ikea table arcade machines.

However, we have opted for 6 buttons and 1 joystick.

In the above website it gives us the .ino file for 4 arcade buttons.. but we want to use the 6.

Can anyone supply me with an updated code so that the 6 buttons work?

Below is the current code that works fine with 4 buttons and I have attached the current .ino file.

Any help greatly appreciated.

Cheers

Nich and kids!!!

Can anyone supply me with an updated code so that the 6 buttons work?

You can. It's really simple. You can't expect us to, since you have not defined where the extra switches (NOT buttons) are connected.

  pinMode(0, INPUT_PULLUP); //Joystick Up 
  pinMode(1, INPUT_PULLUP); //Joystick Down

pinMode() is NOT used for analog pins. They are input only.

int coin = digitalRead(8);

Which pin would THAT be?

You can choose two additional pins and replicate the existing button code for each of them. The missing piece is figuring out what key number you pass to keyboard.press and release. Further, on that topic, do you have to change the code on the Pi to accept it?
