To avoid situations you have stated in your second and third comments, any idea how I should modify the circuit.One way I can think of would be to adjust the 47K pot so that its resistance is little more than the LDR. By increasing the value of the pot , I can also make the alarm less sensitive...
R8 is a 47k pot and R9 is an LDR. I made those changes in the above figure(wrote them in black) but seems like they weren't saved.Extremely sorry about that, I have posted the correct figure. Also output goes from low to high
We have to make a miniproject as part of my engineering course. I chose the above burglar alarm. I thought that there were some mistakes and I have made some changes (therefore some things are written in black). I did be grateful if you guys could confirm whether the circuit will work...
