This mailing list doesn't do attachments that might be deemed
viruses. The file suffixes on the black list is completely out of my
control.<br>
In addition, the total msg size limit is 100k. So when the digest
came through with the attachment it was blocked in moderation. But
that prevent the attachment from being snatched. <br>

style="font-size:11.0pt;font-family:"Calibri","sans-serif";color:#1f497d">Just
a follow-up on my efforts to measure current using the
ACS712 Hall Effect sensor. I decided to buy a 5 amp
model to experiment with, thinking the 20 or 30 would
be a little dangerous just for testing. I received it
from Amazon via UPS and the package appeared to have
been run over with what looked like tire marks and the
pins were bent down and over to the side but not
touching. So, I made a rig to do some testing at first
with a lamp with no success and then DC with no
success. Today, while I was looking for more wire I
found one of my wife’s old hair dryers with 1200 watt
rating. If I turn it on low in “air” mode it produces
over 4 amps – perfect. As soon as I connected and
turned it on the amps on the Serial Monitor jumped to
a little over 4 amps. I couldn’t believe it so I got
my clamp-on and surprise it also read a little less
than 5 amps. It’s an old analog so it may be a little
off on the low end. Side note: I accidentally ran the
dryer way above 5 amps and the reading went erratic
all over the place, but came right back. That ACS712
is a tough and forgiving little piece of hardware to
be smashed and overcurrented and be okay. </span></p>

I added a little code to the code I borrowed from one
of the Arduino forums and did a screen shot of the
code and the output on the SM. I’m attaching the
screen shot so if anyone wants to please comment on
any of it I would be most appreciative. </span></p>
