I am Justin Bancale and I am building a flight simulator that moves with the plane on the computer and it will be donated to a school and I need help with a schematic for a low pass filter that takes a 0-5v PWM signal from an Arduino Uno and changes it into a negative 12 to 12 volt analog signal I don't have a lot of money so I was wondering if you'd be willing to do it for free or for trade. I have a video card with 2 dvi ports, and an old 3rd party n64 controller (good for making portables). make an offer on 1 or both items best offer wins!!
Thanks
Justin
