Irbutton will never be less then 9 because you and it with 127. So your if will always be false.

so u r saying that i should and it with 65???
BTW it works with less than 9....

[cncmachineguy]

I'm sorry, I am completely wrong. Need more coffee. I was thinking OR.

[engineer7]

np.you had me thinking there for a moment
but my problem is the same just a pulse spike of 5 volts on button press i want to keep it permantently off or on when io press the button only once...

I'm not very familiar with AND/OR and masks yet, but I wouldn't be surprised if your program did just what you told it to do.

IF TMP>=500 says to turn on during pulse and then off as soon as pulse stops.

if tmp >= 500 then
Will never be as tmp is BYTE size

[cncmachineguy]

Every iteration of your loop turns the led off right after start. There's you problem.

Very good, a byte can count from 0 to 255.

That could give unpredictable results (except for the gurus that can most likely figure exactly how it will go screwy ); it may work, it may not.
