8. Interface an IR proximity sensor module to the FPGA-bot using jumpers connected to the Cyclone male header socket. Attach the module in front of the header socket using foam tape. Alternate driving the left and right IR LEDs at 100Hz. Check for an IR sensor return and develop two signals, LEFT and RIGHT to indicate if the IR sensor return is from the left or right IR LED. The IR LEDs may need to be adjusted or shielded with some heat shrink tubing so that the floor does not reflect IR to the sensor. Use the LEFT and RIGHT signals to drive the decimal points on two LEDs to help adjust the sensor. It may be necessary to filter the IR returns using a counter with a return/no return threshold for reliable operation. Using a clock faster than 100Hz, for example 10kHz, only set LEFT or RIGHT if the return was present for several clock cycles.
