Picorder SCRIPT

# 5 Feb 2022
This is the picorder Python script I wrote for the "SciFi your Pi" challenge in 2015

Now 6 years later, I still retain the Picorder along with other projects I've developed and worked on over the years.
Being recognized as one of the "Final Four" in the international contest, let alone being selected
as a contestant is a great honor and privelege. Since then I've used the Raspberry Pi microcumper 
for many of my home projects including and internet radio, surveilliance camera,
touch screen pc browser, and more. Thanks again Element14 for the opportunity.
