Hello, I'm a newbie,
I've done some simple projects. But there is one that I can't get to work.
I want it to be solved before I can go on with my hobby.
It's this one : http://www.instructables.com/id/Flashing-LED-using-555-Timer/?ALLSTEPS
I built it exactly like that, but the LED isn't blinking, no , it gives off light continuously.
The power supply is a lego train adapter.
I've used the search function, this guy had the same problem : http://forum.allaboutcircuits.com/showthread.php?t=46620
But my power supply is ok. Now, I read the sticky about decoupling caps.
But it should work as described on that instructables site, right ?
I used an NE555P and jumper wires (longer than on that site), all ordered from ebay.
I tested the capacitor on the voltage. It simply reads a continous value : 1.4 V.
What could possibly be wrong ? Are my IC's ok ? (Because I couldn't get a 4011 IC to work either, which I used in a project with multiple NAND-gates)
