Using Boe Bot IR parts with only 1 I/O pin per sensor

· I have developed a circuit that uses the parts provided for the IR in Boe Bot kits. My new robotic platform is called Mini Hightower and was designed for easy modifications and add ons. I used 2 555 timers to fake a TV remote·IR signal·to drive the IR LEDs and added a tuning pot for finer distance ajustment. Here is a video in action. Sorry about the schematic, I forgot to add a 100 ufd cap across the 5 volts on the board. It is needed for sure. The last pic was using the original parallax set up using 3 I/O per sensor.
