Hi all.
I've got a doubt about the adjustment of duty cycle for an astable multivibrator using 555.
If you have a circuit for a timer with 1kHz please send it.
Thank you

Re: Astable operation

hi

here's the final circuit with all the calculations already done
it should give you a square wave of duty cycle equal 0.6
you easily change the duty cyle but it will affect the frequency
let me know if it works for you

make sure the value of T(on) and T(off) equal to each other by properly fixing R1 R2 and C
