Hi,
I’m having trouble trying to adjust the pots for the AD and R parameters. Can someone with a knowledge of the 555 timer help me out?

Are you in doubt that the schematic is correct, or your implementation of this schematic? Maybe if you describe the problem you are experiencing, someone can help.
