Hi.
I'm trying to design a 555 timer circuit powered by +12V and outputs +5V pulses with variable frequency and variable duty cycle.
It should have :
Clock Range Switch : x1 or x10 setting
Clock Rate Knob : 0.1 Hz - 10 Hz (x1)
1 Hz - 100 Hz (x10)
Duty Cycle Knob : 10% -90%
The duty cycle range can be wider if possible. Those % values above are just the bare minimum.
Here is a picture of how far I got. Not sure if this is right or getting close. Could someone please help me with the values and needed new components?
Thanks so much! Happy Holidays!
