Hi all,
Here is my code to measure light with TelosB. The program should write the
light value to serial port. It does but it only outpus 4037... I know that I
have to convert this number, but the thing is the sensor is not working at all,
I mean if I cover the light sensor and make it dark, my program still outputs
4037 to terminal. Can you please check my program?
