Hi
In the Attachments There is a light alarm circuit but there is a problem in these circuit:
When a person cut the light (pass through the laser beam) the alarm will work only if there is no light, in my case these will take less than a second thus I will not hear the alarm, so how can I let it work until I disconnect it in myself.
Thanks...
