Re: Strange IR sensor movement with default tracker code
you can tell if the sensor is working by putting a scope prob on the signal pin and pointing it at the beacon

or if you dont have a scope, some digital volt meters have a frequency function - when the sensor sees the signal it should register 100Hz

and if not, put it on DC volts - you should get a slightly lower voltage on the signal pin when it sees the beacon (because it pulses low for 10 or 20% of its duty cycle) that when it doesnt see it (flat 5V output).

at least this will give you some indication that your sensors are working
