Hi All! I'm using an ADC0838 to convert an analog voltage to a signal I can read into the BS2. I can't tell if my problem is with a the program (attached) or with my connections. When I debug the output from the chip, all I get is a full byte in decimal form (255). Something isn't right because I am varying the voltage…

I was just using the pieces I have. What kind of op amp would I need? This is the same op amp I'm using when I got the ADC to work while using a pot instead of the photocell as my power supply.
