Re: IR sensor trouble

The only way the pattern stops is when we unplug the beacon. Is this normal output?
The sensors are very sensitive to light coming in from all sides of the package not just the front. This allows it to "see" reflections from everywhere. Try putting electrical tape around the sides and back of the sensor and try again. You have crossed the wires, right? The sensor is not pin to pin to a PWM cable.
