Advice/limiting voltage swing to Stamp

Hi Derryck,
Suggest you use 1N914 or 1N4148 signal diodes to clamp the incoming signal to
within limits mentioned in earlier email. Configuration of diodes is
straight forward. "J" is the junction of the two diodes, the 10 K ohm
resistor and the input to the Basic Stamp. The 10K ohm resistor could be
easily increased depending on what the limits of loading are on the singal
source.
+5 volts

Diode 1

input signal
10Kohms----J
input to Stamp
cath
Diode 2
anode

Even though the 'drawing" is a bit crude, I trust that you can decypher the
connections. If, not, please contact again. Hope this works for you and
would like to hear about the results. Am interested in your use of Basic
Stamps as I intend to use them soon for various applications.
Regards, Burt
