the values does change when using a multimeter so the LDR is working.
I will try a smaller resistance to see if that helps.

i tryed using 3 different resistances and no result i think i am cursed!!

well actualy the manuel
well actualy the manuel calls for a 10K resistor not 100K, should I still fallow your testing methode?
its in the difference
The input pin is in between two resistors. one is fixed and the LDR is variable. They work as a voltage divider. If the two resistors are equal, the input pin should receive half the voltage of V+.
If V+ is the same voltage (say 5V) as the picaxe is receiving and the input pin is in between two equal resistors , you should read a value of 127 or 128.
Now change one of the resistors and the voltage is no longer divided equally and you should receive a different reading on the input.
You wont fry anything if you use 10K or 100K. If you connect the input directly to the ground you get a reading of 0 (zero) connect is directly to the V+ with any resistor (dont leave it out) you get a reading of 255.
if you still get a reading of 225 on the input pin when you connect the pin directly to ground then you are reading the wrong pin or the picaxe is broken.
Can you show a picture of
Can you show a picture of your connections to the board?
any updater on this? im
any updater on this? im planning to use the ldr on edge detection
Personally I never got it
Personally I never got it working, but you should try it for yourself.
