i just told
rd1 = 1;
rd2 = 1;

 

[khangzing]

That's why I asking why the 2 pin need to set to 1?and can u give an example about the offset?

 

[Venkadesh_M]

for example

you are placing the reflector in 1 m
you are getting i value 100 means it is more than the offset(80) and the output will be some pin high
and if you placed some where else and getting 70 means the output will be different..

 

[khangzing]

If 70 output will be?so more than offset or less than is better?

If not working varying is better.............
