Frustration eh....Is there a different circuit I could use that would serve the same purpose?
That was the first thing I triedSounds like your battery is about dead.
I don't see pin 12 going to the paralleled inverters.Sorry, it is a buzzer not a speaker. I removed it anyway, just hooked up the LED but its the same, just staying on permanently. Whether the sensor is connected to the breadboard or not is having no effect on the LED. Is there a different circuit I could use that would serve the same purpose?

Very easy just download the free software from http://fritzing.org/home/ draw your schematic in fritzing and it will then produce your layout on a breadboard easy.Hi there,
I'm pretty new to electronics and am having a bit of trouble trying convert the attached schematic diagram onto a breadboard to test. The main issue I'm having is understanding linking up the IC, is there a way of simplifying the circuit diagram?
Thanks
I built your circuit. I ran it from 12 V instead of 9 V and I don't have your sensor. When I touch the point where the sensor goes with my meter the LED blinks once. Is that what it is supposed to do, or is it supposed to blink continually? On power on I get one blink. It does the same thing at 5 V.Hi there,
