I have a schematic of a LASER alarm which can active when the laser beam braked by something. And remain on until reset button is pressed.
Here is the schematic...
But the there is a problem in the diagram.... I don't know what... May be in the switch connection or something else..
Please help me to fix this or any other idea to build the alarm ....
