Hi.
I have tried making this circuit but my led just keeps lighting.
I have re-built it several times, thinking i made some mistake connecting it, but same isue led is just on.
I tried with different 555, bc337 and 2n2222 but no luck, any ideas what i might have connected wrong?
Thanks /K
Update, I found the issue by replacing R4 100k ohm with a 1m pot, value needed for circuit to work was 1.3M ohm
