Hi Alec_t,
I used the monostable circuit, I used this circuit:
https://www.utm.edu/staff/leeb/mono555.gif
Resistor is potentiometer 500K and capacitors are 15nF, then I can supply 20Hz 50% duty and adjust with the potentiometer. Sometimes I got strange behavieur at motor and then I saw that if I didn´t supply the PWM signal from the signal generator, the 555 output itself 50% 50Hz signal. When I supply 5V at input then the IC doesn´t output anything.
Thanks everybody.
