I have been sort of heading that way for the last few weeks. Mainly due to
the cost, and the fact that I usually use the Light Sensor with the IR as
sonar, and I was thinking that I might get better distance with a passive
(CdS) sensor.
My latest robot is very wide and very short ( 5" x 20"), so I want to
implement two IR Sonars, one each side so it can tell which way to turn when
approaching a wall.
