This time I'm going to use the USB gamepad method as all I need are a few buttons to change a piece of music that's playing.
I'm making a giant Buzzer game using the Raspberry Pi for the logic and buzzing as well as playing different tunes in the background. When I press a button a can change the tunes. The Pi will be battery powered and I will be using a battery powered radio with an external input for for the audio as it will be set up in a school playground. I used the USB input previously for a stepper motor thing I made - Blog post with code and explanation for the gamepad and the stepper motors - http://winkleink.blogspot.co.uk/2013/04/raspberry-pi-unipolar-stepper-motors.html This all worked without a display. I just SSHed into the Raspberry Pi - ran the code and off it went.
