Just got my sparkfun stuff today, and while testing my Maxbotix LV EZ1, I can hear a faint clicking noise a few times a second. Also, the Analog values seem to be completely inaccurate. I think the accuracy may be with the Power supply (ATX computer psu). The clicking noise can only be heard when the sensor is pointed directly at my ear. The sample rate of this sensor is 20Hz, so I know it shouldn’t be the sampling device making the noise. Any experience with this strange problem?
Fixed, all it working 
I think the problem was, that during the calibration period, it was facing something too close, causing an issue. As for the clicking noise, it is normal, and does not bother me.
