Hi everyone. i have an assignment to give a 10 min speech on a job that i would like to have in the future for school. of course im gonna give it on being an electronics engineer :lol: . so i got the idea to design and build a little beam alarm system so i can show the steps, calculations, etc., some of the things that would be involved in being an EE.
here is the circuit that i have designed. The voltage divider part works. And the delay for the buzzer to stay on for a couple seconds also works. I tested both of those parts seperately.
It doesn't work though. Where am I going wrong? and please don't point me to another circuit, remember, i'm trying to design this myself :lol: thank you very much!
