LED sensor device

[WolfieTats]

Two sensors are mounted on a half-white rotating disk as in the figure. Sensor output is 5V for white and 0V for dark. Specify the digital element or elements to put in the black box so that the LED is ON for clockwise rotation. (hint: include a D flip-flop)

If I do the homework do I get an A?

I suggest you become familiar with what is called a Quadrature Decoder.

I'll let you know if you did get an A when they grade this thing. Thanks!
