IR trip wire with discreet components Answered
I am in need of help and I am going insane with this. Question is about a simple circuit with IR sensor/tripwire part and 555 timer which would keep the alarm buzzer on for thee seconds. No fancy stuff like arduino or relay or anything like that just LEDs, resistors, transistors, 555 timer and a buzzer.
I got the IR sensor part to work and the timer part to work, but when I try to combine them everything goes haywire and nothing works.
I have IR photo transistor TOPS-030 as the IR sensor. I am really starting to lose my mind with this and it has been three years since I started doing this project. I got diagnosed with undefined neurological disease (probably MS-disease) which has slowed my down even more. I worked on the circuit every now and then not every night during the past three years =)
I know this circuit is simple and it can be put together in a brief moment the thing that is driving me crazy is the fact that when I got something working then everything goes haywire. Doing very basic beginner instructable describing this circuit would be very helpful even to others not just me. It would also keep the knowledge of using discreet logic up in these micro controller days.
