I breadboarded the digital noise module. It works good and has
fascinated me for the last few days. Just a couple questions:
The 2 digital outs are a little too hot for me (11-12V).I'd like to
chop them down to 5V...or maybe 10V...or 7.5V. I figured out one way
to get the outs down to about 6 volts. From the cathode of the LED is
a 2.2K to ground then a 10K (instead of 1K) to the out jack, and a
15K connected from out point to ground. I asking if I can do this in
a simpler (more proper) way? I'm fearfull my output impedence is too
high. Should I be changing resistor values somewhere else in the
circuit instead?
second question is in my next post to make archive searching easier.
Thanks,
Peng
