some years ago I tried to build up a multivibrator circuit and i
attached red LED so that i glowed around a frame the trouble is that
it worked nicely for some time then after some weeks when i turn it on
the LED would glow then start to dim then fade out totally.I used IC
555 for multivibrator with 9v DC supply got through a rectifier if any
one knows the answer please mail it to me at [email protected]
