Hello
Ive some problems with the 555 Timer. I'm trying to get an defined pulswidth signal out of a current signal.
My problem is the circuit should work with 0.25 to 1 Hz on the current signal. I've got it running at 1 Hz but if i try to go lower the timer starts to get crazy.
im a really noob in stuff like that and happy with every little help 
i hope someone can help me 
thank you
