how to control 555 resisters with PIC

[skimask]

thanks for the info

If you really wanted to get crazy, you could easily drive an R/C aircraft servo to turn a rotary switch connected to a bank of capacitors (ya know, ka-chunk, ka-chunk, ka-chunk) and another servo to drive a linear pot. Drive servo's is easy with a PIC also. At least you'd have something mechanically silly to watch, something a tad bit over engineered.
