IR Detection

What resistors would you recomend for IR Detection with a BOE BOT?· I have a 4.7 K OHM resistor, but it is too strong, my BOE BOT gets stuck everywhere it goes, because it detects things over half a foot away...Anyways, I wonder which resistor seems to be the best?

    There is no resistor connected to the detector; the resistor you're using is for the IR LED. You can increase the size of that resistor to decrease the range, or you could "detune" the circuit by adjusting the modulation frequency.
