Hi, pink_scarf. Welcome to ETO!I need to construct a burglar alarm with an IR sensor and LDR for an electronics project.
I can make 2 separate circuits or combine them as one. However I need a circuit diagram to start building it.Please help me.
hi Brevor,Sorry thats still not very clear, I imagine the IR emitter and receiver would be a "beam break" type of alarm.
But what is the LDR for ?
