555 timer

[tooobiCH]

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

Hi

Can you please specify which signals you receive, and what you would be expecting for lower frequencies?

When you modify the frequency, you just change the frequency of I1?
